Common Questions and Answers about Pacemaker of human heart

pacemaker

Avatar n tn perhaps the doctor said the body rejected the pacemaker. In either case it may have been a simple way of saying the pacemaker could not supported needed heart activity.
781550 tn?1236029747 I wrote to the Princess Alexander Hospital and they called me in for a thorough checkup of my pacemaker. It was regularly running my heart at 160 bpm. The penny dropped! There is a setting which detects when one is exercising. It senses vibration and increases the heart rate. However, vehicle vibrations can fool it. So if I got into a rough vehicle, my heart rate shot up. If it stays up for long enough, I get a heart attack. Solution - turn the setting off. All cured. Well, not quite.
Avatar m tn In other cases, people may have no symptoms but are at high risk for dangerously slow heart rates because of disturbances of the electrical system of the heart. A pacemaker may be recommended for these people before symptoms occur. There are no electrical disturbance shown with your post?! Because a wrong decision can be very serious I would hesitate to second quess a doctor's assessment.
Avatar m tn 2) Considering her need for a higher dosage and her occasional heart block, the combo of verapimil and a pacemaker is an appropriate next step. As I recall, a member of this board, scouser costa rica, has a pacemaker like your wife's doctor is recommending and it's working out well for him (he also takes amiodarone to decrease the frequency of afib episodes and to lower his heart rate when it does occur).. 3) There are two types of ablation to consider.
Avatar m tn the heart is working all alone, then the rate would increase, not decrease. I thought if a human heart for example was beating in a lab using only its built in pacemaker, it would run at around 100 bpm? The vagus nerve is responsible for the parasympathetic system, which slows the heart down. So if cut, your heart should speed up? Was it a Doctor who told you the nerve may have been damaged? The Vagus nerve also controls of lot of digestive functions, have you noticed any problems?
Avatar m tn After getting the pacemaker, my BP readings have been progressively worst week by week. Befor the pacemaker, for years my top (systolic) readings used to around 110 to max of around 160, and after the pacemaker, they even reached worst level of around 190, and yesterday scary level of 225. - Even though my family phys added Clonidine to previous BP-meds of Altace, HCTZ, and Cardura, my BP keeps moving higher an higehr each week... I never had so high numbers before the pacemaker.
Avatar n tn Remember that after an ablation that it can take months for your heart to get back into its normal pattern of beating. MVP is a very common afliction in the human race 25 to 30 percent of all of us have it. I don't know much about pacemakers but i would talk to my doc because it seems to me that the pacemakers job is to regulate your heart beat so he/she may need to re-set it....a simple thing non invasive.
675084 tn?1233087505 Can your pacemaker be set to make your heart beat a certain rate? My mom's Medtronic pacemaker would not allow her heart to beat under 70 beats per minute. She had a dual pacemaker. Ask your doctor if they can set your pacemaker.
Avatar n tn I ended up having every type of SVT except Wolf H Syndrome. My cardiologist was scared he would have to put a pacemaker in at the time and wants to go back in for another ablation 3-d mapping in 3 mths. My questions are: 1. Is it normal or common to have more than one type of SVT? 2. If I ended up with a pacemaker could I have more children? 3. What would the risk of future pregnancies be with and without the pacemaker??
Avatar m tn Unless your mother is in superior condition and will live many years I would not subject to the pacemaker. The pacemaker part is fine but not the defrib part of it. If she slips away that defrib unit will bring her back. As some one who is up in years I would not want that. A nice peace passing is what I would want. Warm regards.
424096 tn?1223931472 s slow empting my stomach i have had alot of test done and this is what it should i have. i have alot of health problems to. is it safe to have.and one dr. put me on zoloft what is it for? and zanex what are those for? i take alot of meds now . i think i am their guinie pig.
Avatar n tn I am a 30 yr old mother of 3 with a pacemaker. I have had the pacemaker for 3 years in July. It was originally placed because of a severe problem with fainting. My heart was stopping for nearly 50 seconds(documented) during these syncope episodes. The pacemaker has basically cured this problem. At my last visit they said it was working 25% of the time. Whatever that means. But now the pacemaker unit has shifted for the second time.
Avatar n tn And two, in the setting of this A fib and a slow heart rhythm, putting in a pacemaker may reduce the amount of atrial fibrillation you're having. But more importantly, the presence of a pacemaker will allow your doctor to put you on anti-arrhythmic medications safely. If you have a tendency for a very slow heart rhythm, if you were placed on and anti-arrhythmic medication, your heart rate may get so slow you could get dizzy or pass out.
Avatar f tn no. 84 is not high, it's only generally if it gets to over 100 at rest that tachycardia is diagnosed. As long as his heart rate is stable and there are no rhythm problems, then there is certainly no requirement for a pacemaker.
Avatar m tn A pacemaker is a small device that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm. A pacemaker may also be used to treat fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy. A pacemaker implant is more for assurance of good, normal heartbeat than a remedy for heart failure.
Avatar n tn Jon is correct. You can't judge the complete population of pacemaker devices on the probability of run of specific models that may have had a manufacturing problem. It appears to be a recall or heads up for any probable problems.... A malfunction of a device is 1.4 per 1000. One out every 50 devices manufactured is defective is ridiculous...should be ashamed to post the comment.:) The pacemaker should not even be an issue.
Avatar f tn From what I understand, first degree heart block is a delayed transmission, without missed beats, of an impulse from the atria to the ventricles because of an impairment of the conduction (electrical) system and is generally benign. ie usually doesn't progress to complete block as is sometimes the case in 2nd block. What did your doctor say about the type II episodes?
754107 tn?1233668478 hi i also have heart block stage 2 with a pacemaker fitted i was diagnosed 2 years ago at the age of 32 i also found out last month that i have svt too .
Avatar f tn How do you know that you have low heart rate before you wear the holter monitor? What type of problem you noticed before you realize this problem? Usually younger and more active person experience low heart rate at rest.
Avatar f tn I'm wondering what actually limits the size of the pacemaker? Is it the battery size? I often wonder why a more biological connected pacemaker hasn't been developed yet. A tiny circuit on the heart which uses the origin of the signal in the right atrium, then uses delay circuits and switches to allow current to pass through to different parts of the heart. No battery, just components using resistance etc.
Avatar m tn It is called the Triboelectric phenomena and are rarely considered in the differential diagnosis of pacemaker interference or artifacts in the standard electrocardiogram. Static electricity or triboelectric phenomena occur more commonly during very cold weather and very low relative humidity. Triboelectric signals are usually wider and more irregular than pacemaker stimuli and often recognizable as artifacts.
Avatar n tn Although your BP is low, it is not terribly, horribly out of line, and even though your heart rate is quite slow, I have several friends with your heart rate, and they lead perfectly normal lives. So here are two or three questions: 1. Except when you are about to faint, how do you usually feel? Are you tired, weak, and short of breath much of the time? If so, that argues for a pacemaker.
Avatar f tn My blood pressure has been running low around 80/60 and heart rate 93 I get a dizzy feeling when this happens and my heart feels like it is going to pop out of my chest. Could this because they have my pacemaker set so high, before the pacemaker my heart rate was in the 40's.
