Avatar n tn Please can someone explain why a patient with a pacemaker kept her paced rhythm of 70 bpm with a fever 39.3 to 40 degrees C? I thought pacemakers could vary the rate to meet metabolic requirements. Thank you.
Avatar n tn - the physique does not suffer from any handicap.(let us understand by there that all the cells of the body achieve their respective functions suitably). - the sensitive is not seat of any no null feeling - the psychic is governed by an activity neither too slow rapid nor Triple neutrality can be broken by various incidents which occur daily (accidents, irradiation, intoxication, contamination… etc.).
Avatar n tn You have suffered a great injustice, and I'm sorry for your experience. I do not know what the black substance was, or what the results of exposure may be. However, the skipped beats may be caused simply by confusion in the heart muscle itself. Your heart cells are all capable of contracting and causing the heart to beat. Usually, this job is segregated to specific cells that most people refer to as the "natrual pacemaker.
Avatar f tn IVC is very dilated and does not collapse with respiration. estimated pulmonary sytem PR of at least 50mmhg. what does this mean? does it mean that there is no treatment for it? if there is what type of treatment there is. .
255722 tn?1452546541 The spread of electricity throughout the heart muscle is possible because all heart muscle cells, not just pacemaker cells, are excitable. Usually, the heart muscle cells keep time more slowly than normal pacemaker cells. This allows the pacemaker cells within the SA node to be in control of generating and pacing the heartbeat.
Avatar n tn Hi, am doing some research. please can you explain why an 89yr old with pacemaker kept her 70bpm pulse with a fever of 40 deg.C. Also what were the metabolic implications for her? Many thanks.
Avatar m tn Anti oxidants help neutralize the free radicals that are generated as a part of the anaerobic respiration and these free radicals damage the cells. So anti oxidants like fruits, green Tea would help neutralize the free radicals. 5. Metabolism CO2 is a by product of metabolic activities . So doing exercises ( and NOT hyperventilating while doing those ) , and non sedentary activities will definitely help metabolism and further healthy growth in body cells. 6.
Avatar m tn In large and medium size vessels and in the kidney, endothelial dysfunction leads to enhanced growth and vasoconstriction of vascular smooth muscle cells and mesangial cells, respectively. These changes in the cells of smooth muscle lineage play a key role in the development of both atherosclerosis and glomerulosclerosis.
1580703 tn?1651904887 The peripheral system does not get the right impulses for respiration and hence the stoppage of respiration. As a result the person is aroused from sleep. For central apneas therapy is by treating the underlying cause and again SV BiPAP, could also be effective as it is pressure support ventilation. With improvement in oxygenation the other symptoms may resolve. Discuss these options with your doctor when you happen to meet him next time. Hope this helped and do keep us posted.
696415 tn?1228229959 The sinoatrial node (SA node) is a group of cells positioned on the wall of the right atrium, near the entrance of the superior vena cava. Cells in the SA node will naturally discharge at about 70-80 times per minute. Because the sinoatrial node is responsible for the rest of the heart's electrical activity, it is sometimes called the primary pacemaker, the natural pacemaker.
Avatar n tn The spread of electricity throughout the heart muscle is possible because all heart muscle cells, not just pacemaker cells, are excitable. Usually, the heart muscle cells keep time more slowly than normal pacemaker cells. This allows the pacemaker cells within the SA node to be in control of generating and pacing the heartbeat.

Avatar n tn By the way...I noticed the ??? near the "natural pacemaker" portion of your post. Thought I'd take a minute to help you understand. The sinus atrial node is a clump of cells in your heart that put out an electrical current that causes the rest of your cells in the atrial center of your heart to contract. The electrical current continues into the ventricular node and causes the bottom of the heart to contract immediately after that.
Avatar m tn Yes, the condition can infect the heart's natural pacemaker. The heart's "natural" pacemaker is called the sinoatrial (SA) node or sinus node. It's a small mass of specialized cells in the top of the heart's right atrium (upper chamber). It makes the electrical impulses that cause your heart to beat.
Avatar m tn I had gall bladder removed a few months ago, and I remember pain with each respiration. The pain at night was intense ( I did not realize at that time that the fat in meals was causing the pain during digestion) . Of course this is just a mere input. I hope that you are feeling better soon.
Avatar n tn If the cells are dead, a cath would not be of any help. If the cells are hibernating due to low blood flow to the area, medication can increase the blood flow to the area....angina with stress and rest normal blood flow. Your symptoms, if any, would be the issue to correct. If you are having chest pain (angina) with exertion and rest relieves the chest pain that would be stable angina and medication can be effective.
Avatar m tn ve had it myself. This is beyond normal changes in rhythm that occurs with respiration. Something to keep an eye on and report to your physician.
Avatar n tn I started to get episodes of AF set of by bending down exercise ,drinking etc now it is controled by tablets but I still cant get back to full fitness ,i was a keen runner before but now I tire easy and can only manage a snails pace if i jog my legs drain of oxygen and seize up and my respiratory system works overtime ,do you have any idea what this may be -------- lactic acid ? poor respiration ? magnesium ?
Avatar f tn These were stem cells made from my OWN STEM CELLS not embryonic. So, no chance of rejection, no extra pills to take. There is over an 80% chance of improvement. My EF was between 12 and 15% before new stem cells. Have not had another EF test yet. I am diabetic(insulin dependent.) I do have a defibrillator and pacemaker. Would be only too happy to share my experiences - they will be on-going!! It is a shame one has to go out of the country to have this procedure done.
1744581 tn?1311302411 I'm a 34 yr old female & I have a pacemaker for congenital complete heart block. I had it replaced for the first time 5 weeks ago. A recent echo showed severe hypokinesis of the apical wall. Ejection fraction is 50%. My dr said this could be due to wear my lead is at. I returned to work a 2 weeks ago after being off for a month after my surgery. I'm a prep cook & my job is pretty easy. I'm on my feet all day but I've been doing the same work for years.
1400314 tn?1280731525 d like to know what got the ventricles going again. My understanding is that the pacemaker cells in the Ventricles can take over in the event it doesn't receive a signal to beat. this is called an "escape beat". On you holter they should be able to tell if the ventricles fired an escape beat or if the next beat was something called "normal sinus rhythm" or NSR. usually the ventricles will fire an escape beat within 3-4 seconds of not getting NSR.
Avatar n tn There can be different reasons, but it generally finds a different way around, through normal heart cells. However, this can cause a delay, meaning the right chamber is contracting slower or is delayed compared to the left. This is probably what they are referring to with regards to borderline. Causes could be genetic history, certain infection types, recent heart attack, heart disease. If the cells are damaged, then there is always the option of a pacemaker.
Avatar n tn hypokinesis can also be the result of stunned cells. Stunned heart cells affected by a heart attack can be revitalized if blood/oxygen is quickly provided within a few hours to the area affected by an acute heart attack. Akinesis is different from hypokinesis in that the heart cells affected are necrotic (dead). Stem cell therapy may be helpful for that condition. Five years ago I had hypokinesis of the left ventricle wall and a low EF.
Avatar n tn my father had a heart attack in 1984, a pacemaker four years ago andnow is diagnosed with heart failure, is this normal?
Avatar f tn heart cells are probably trying to take up for the loss. However, not being the natural pacemaker center, these cells fire at inappropriate times causing what you are feeling as palps. As for what to do, I can only tell you what I would do. I would get the thing fixed or replaced ASAP.
Avatar n tn Hello, my father (early 60s) is on an ICD. His cardiologist wants to make the heart completely dependent upon the pacemaker, as the medicines my father is on aren't working. Unfortunately, I was unable to sit in on the meeting between my father and the cardiologist. My question to you is this - do you know the name of the procedure that would fully sever the nerves which incite the heart to beat?
Avatar f tn My daughter was diagnosed with a variety of heart problem when she was two months old. She currently has a pacemaker which she only uses when her heart rate goes above 115 bpm. When she has surgery 7 years ago the surgeon lost a surgical needle in the center (av node) area of her heart. Could the needle be the reason she is having heart block? She is ten now.
