It messed <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> bottem part <span style = 'background-color: #dae8f4'>of</span> my leg up and I have permanent bad blood flow <span style = 'background-color: #dae8f4'>in</span> it now.That night I had it done I had a complete heart block and lived passed it! I guess I am just scared and not sure about the whole thing again?????? If any one els has had it done please write me back please! Ablation of the heart and thinking about the second time around!!!!!!
UPON A RECENT ECHO AND EKG, I WAS TOLD THAT <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> RIGHT SIDE <span style = 'background-color: #dae8f4'>of</span> MY <span style = 'background-color: #dae8f4'>heart</span> IS ENLARGED, ALSO SHOW SIGNS <span style = 'background-color: #dae8f4'>of</span> VALVULAR DISEASE. theY <span style = 'background-color: #dae8f4'>are</span> SAYIinG THAT 3 of the 4 VALVES are SHOWinG SIGNS of DISEASE.( DEFECTIVE). I ALSO HAVE M.V.P., AND A heart MURMUR. I ALSO HAVE COMPLETE BLOCKAGE, in the UPPER CHAMBER. I WAS LED TO BELIEVE THAT I NEED SURGERY TO CORRECT the WHOLE TO STOP the RIGHT SIDE of MY heart FROM GETTinG ANY LARGER.
At first I thought he was really listening, but now I think it's just his opinion of <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> drug companies <span style = 'background-color: #dae8f4'>are</span> just getting <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> way. Believe me I've taken just about all <span style = 'background-color: #dae8f4'>of</span> them <span style = 'background-color: #dae8f4'>in</span> 17 years time. I thought Tirosint was going to be well suited for me since I seem to not retain many meds, because it was a gel cap and not many fillers, but I think it might have been a mistake to leave the synthroid and not increase it instead.
A bursa is a tiny fluid-filled sac that functions as a gliding surface to reduce friction between tissues <span style = 'background-color: #dae8f4'>of</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> body. there <span style = 'background-color: #dae8f4'>are</span> 160 bursae <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> body. <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees. the shoulder is the most mobile joint in the body. When a person reaches overhead, the tendons that move the shoulder must glide almost two inches past a bone surface.
Generally, PAF which has a PV origin, is treatable with RF ablation, and these days, <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> techniques target isolation <span style = 'background-color: #dae8f4'>of</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> foci (electrically active <span style = 'background-color: #dae8f4'>cells</span>) <span style = 'background-color: #dae8f4'>located</span> in those pulmonary veins...with no, NO, pacemaker requirement. the pacemaker is needed when the ablation is aimed at the AV node (central natural pacemaker) in order to stop your heart from beating too rapidly and erratically. I'm sure your doc was referring to the RF ablation of the foci in your PVs.
My sinuses burn and feel like they <span style = 'background-color: #dae8f4'>are</span> cold and I have a headache <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> middle <span style = 'background-color: #dae8f4'>of</span> my forehead.. It is hard to explain but it is a miserable feeling.. I was recently on penicillin for a bladder infection and my mouth was so sore I could not eat. I am wondering if certain meds trigger this re-action. I am 71 years old and have had a few allergies and sinus problems, but otherwise in good health..I wish you all the very best and hope we can find something to stop this...
A very fast heart rate does not provide enough time for the heart's chamber to adequately fill and as a consequence the system may not get enough blood/oxygen and that includes <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span>. Ischemia (lack <span style = 'background-color: #dae8f4'>of</span> blood flow) to <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span> <span style = 'background-color: #dae8f4'>cells</span> can/will impair contractions leading to heart failure. Also a heart rate sustained above 100 bpm at rest stresses the heart and can cause heart enlargement and impair contractions resulting in heart failure and it can cause arrhythmia (irregular beats).
I get sharp, scary numb pricks <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> right side <span style = 'background-color: #dae8f4'>of</span> my neck as well. I too sit <span style = 'background-color: #dae8f4'>in</span> front <span style = 'background-color: #dae8f4'>of</span> a computer for 9 hrs a day. it is really starting to scare me....hoping it isn't something dangerous. I suffer from anxiety as well....curious how many of you do as well?? Please anyone let me know if you find out the problem, solution or medical diagnosis!!

This region controls movement in the groin, toes, and some parts of the legs there are two types of spinal cord injuries: complete and partial. If a spinal cord injury is complete, there is no function below the point of injury.
So, their potential to be pacing the heart is the highest of any other cells. But, any cell <span style = 'background-color: #dae8f4'>in</span> your <span style = 'background-color: #dae8f4'>heart</span> can become <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> dominant pacer. <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> case <span style = 'background-color: #dae8f4'>of</span> PVCs, <span style = 'background-color: #dae8f4'>cells</span> <span style = 'background-color: #dae8f4'>in</span> your ventricles have fired and caused the ventricles to beat prematurely. I could get into a long discussion on why that feels the way it does but I won't for the sake of me not typing this all day. What's so cool here is that the heart has many many built in fail-safes in case the SA node fails to pace the heart.
the most popular source is a focus, ie, a bundle of electrically active cardiac cells typically <span style = 'background-color: #dae8f4'>located</span> at <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> pulmonary vein connections behind <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span>. Foci can be found <span style = 'background-color: #dae8f4'>in</span> other locations as well. Foci are stimulated into stronger action directly or indirectly by a variety of chemicals, which include adrenaline and caffeine. in addition, the general tone of the nervous system can influence how well the foci disrupt the normal beat.
the main research I'm following with great interest is <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> growing <span style = 'background-color: #dae8f4'>of</span> a new patients <span style = 'background-color: #dae8f4'>heart</span> <span style = 'background-color: #dae8f4'>in</span> a lab using their own stem <span style = 'background-color: #dae8f4'>cells</span>. Working hearts for mice and rabbits have been grown fully functional, but this research seems to be slowing down. I think their main concern is ensuring a modified stem cell won't suddenly turn rogue, becoming cancerous. However, I think in the next few years, we will see the first human trials.
there is a quarrel, and often my sympaticotonia wins. <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> cosequence is then tachycardia or varying <span style = 'background-color: #dae8f4'>heart</span> rate. <span style = 'background-color: #dae8f4'>in</span> 2010 I used Multaq at <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> end <span style = 'background-color: #dae8f4'>of</span> the AF period. the sinus rhythm could be returned with multaq and electric cardioversion together. Maybe it could have succeeded even without Multaq. I was waiting for cholecystectomia. My liver enzyme (ALAT) increased for some time, but it could not surely be attributed to Multaq. It could also be due to cholelithiasis.
I myself developed a two day headache from <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> procedure (not to mention <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> loss <span style = 'background-color: #dae8f4'>of</span> trust <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> mental health field). A line from the David G Myers General Psychology 101 manual states: (I am stating the reference to the best of my recollection) "...does a man watching a violent erotic film lead him to give electric shock to a woman... which of course is not the same as slapping a face..." Could ECT be a means of therapy for abusers who have taken their power too far?
From what my ep told me about cryo he liked to use it to test <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> bad spot initially <span style = 'background-color: #dae8f4'>in</span> case there was a chance <span style = 'background-color: #dae8f4'>of</span> a block so he could stop and <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span> could recover but if the spot was safe he would use the RF to be more effective. Though according to my report my spot was far enough away when he discovered where it was he probably had no reason to worry and just used the RF right off the bat.
My research shows in 2-year Catheter Ablation studies, rather than 94% success, 72% were a success, 13% had recurrent <span style = 'background-color: #dae8f4'>of</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> same SVT, and 15% had SVT <span style = 'background-color: #dae8f4'>in</span> a new area <span style = 'background-color: #dae8f4'>of</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span> which needed new Ablations permanently scarring these new areas. Couple this with 1% complications like perforations or AV Node block needing a pacemaker and I am going to try swimming and lifestyle change before considering Ablation Surgery.
Even if you get ventricular arrhythmias, <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> chances <span style = 'background-color: #dae8f4'>of</span> VFIB <span style = 'background-color: #dae8f4'>are</span> still quite low (since <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span> has a couple <span style = 'background-color: #dae8f4'>of</span> <span style = 'background-color: #dae8f4'>pacemaker</span> systems to insure constant beating). Folks that die of VFIB generally have some structural issues with the heart (for example, ischemia which affects the blood supply to the ventricle muscle) I hope this puts things into perspective. I get mostly atrial arrhythmias (PACs and once in a while a short run of AF), and I play soccer and train at a very stressful level.
PVCs <span style = 'background-color: #dae8f4'>in</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> presence <span style = 'background-color: #dae8f4'>of</span> a normal <span style = 'background-color: #dae8f4'>heart</span> <span style = 'background-color: #dae8f4'>are</span> normal. I have had a lot <span style = 'background-color: #dae8f4'>of</span> PVS since a very young age and totally ignore them. Try to cut out caffeine etc and maybe that would help. there are lots of arrhythmias that are life threatening that need research and intervention. Benign PVCs are not one of them. I guess I view these in the context of all that can and do occur and this is really not something to pay much attention to once everything is ruled out.
so, we all end up with hearts that contain electrical cardiac tissue embedded <span style = 'background-color: #dae8f4'>in</span> areas <span style = 'background-color: #dae8f4'>of</span> <span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'><span style = 'background-color: #dae8f4'>the</span></span></span> <span style = 'background-color: #dae8f4'>heart</span> where only structural <span style = 'background-color: #dae8f4'>cells</span> <span style = 'background-color: #dae8f4'>are</span> really needed. Since this arrangement does not affect our ability to procreate, we have evolved with these islands (foci) in place. Most of the time, they are isolated and really don't affect anything. in some folks, unluckily, they may be located near enough to the normal lines of conduction to produce arrhythmias from early on.
