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 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 n tn I have no experience at either golf or using a pacemaker, but as no one has responded I'll offer I associate the electronics/clock implant with being in the upper chest area and I will guess your concern is well founded. I doubt it would be advised to move the location far from the heart, the locations noted...but I do not know.
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 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.
9576600 tn?1475757952 It sounds like certain positions create the block situation which are really unavoidable so it makes sense to get a pacemaker. For a few unfortunate people their svt was located too close to vital areas and blocks can occur. I am sorry that happened to you. I would suspect a pacemaker would fix your palpitation issues but if not it is possible that there is still a little svt left. Considering it's close proximity to vital areas it is possible they were cautious in ablating.
512694 tn?1216161406 That's right - size doesn't matter. If it's located in a sensitive area, you're going to feel it. Let's hope in 10 days you feel better. (I've never heard of gastric pacemaker, just the regular pacemaker for the heart. I'll have to look it up and learn something new.
Avatar n tn t coming from the natural pacemaker which is located in the high atrium. It is normal to have this as long as you are not limited in terms of your physical activity such as climbing stairs, running or playing with your colleagues. If that's the case I would not worry about this at all. On the other hand, if you do notice some limitations, a visit to a cardiologist may not be a bad idea. He would do history and a physical exam and evaluate your heart function with an echocardiogram.
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 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 n tn Scar tissue from a previous heart attack may be an issue if the stress test shows ischemia (lack of blood flow) of the subject area if the perfusion exists for both stress mode and rest. This would indicate necrotic heart cells as the dead tissue would not function with or without stress. If your ejection fraction (normal 50 to 70%) is within the normal range you probably don't have any damaged heart cells. EF is the amount of blood pumped with each heartbeat.
1535596 tn?1292469791 For two or three weeks after surgery, I felt great, now, back to high blood pressure, faster than normal heart rate and no heart block per pacemaker check. I am worried that I am now stuck with a dual lead Biotronik pacemaker for no reason and that there has been a terrible mistake made. The electrophysicist who implanted the pacemaker is now in California, I am in Arizona and the Cardiologist says that I am fine and that he is done with me.
2197254 tn?1338502395 I am aware that a cardiac pacemaker is located near the SA node (sinoatrial node) and usually only affected by, infections or other stress. I guess it would depend on the type of pacemaker you got implanted. It's a question best suited for a cardiologist or your physician.
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 m tn //www.webmd.com/heart-disease/atrial-fibrillation/pacemaker-for-atrial-fibrillation "People with atrial fibrillation may need a pacemaker for a variety of reasons. These reasons include: You have atrial fibrillation that comes and goes. And you have a fast heart rate when you are in atrial fibrillation and a slow heart rate when you are not in atrial fibrillation. This is called tachy-brady syndrome. You had an AV node ablation procedure that destroyed the AV node in your heart.
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 n tn The problem can be due to hypothyroidism or a dysfunctional sinus node (natural pacemaker located in the right atrium). Treatment can be beta blocker medication and if uncontrolled there may be a need for a pacemaker implant (worst case scenario). Low cardiac output can be the result of an abnormally slow heart rate.
Avatar f tn I'd be glad to share the web address for the facility I used in Bonita Springs, FL. It is an American Cardiologist - he's been before U.S. Congress, invited to Dubai, written all kinds of papers. My blood was drawn in his office - like when you get a blood test from the arm. It was then immediately flown to Israel - the courier was waiting to take the box to the airport. Stem Cells were replicated...23 Million. Of that 23 million 80% was specifically "heart" stem cells.
Avatar n tn 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. This will ensure the signal goes to the right chamber the same time as the left.
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 Hi mcalderon91723, If this were me, one of the things I'd like to know would be what terminated the 7.5 second pause? My understadning is that every cell in your heart can become a pacemaker. It's nature's wonderful backup system in case the regular pacemaker signal doesn't reach the ventricles. The noraml pacemaker is a group of cells in the atrium called the "sino atrial node" or SA node.
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.
Avatar n tn s chamber to adequately fill and as a consequence the system may not get enough blood/oxygen and that includes the heart. Ischemia (lack of blood flow) to the heart cells 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). You should be concerned and correct the underlying cause.
Avatar m tn She reset the pacemaker to fire only when needed - below 60. My question is how is it possible for a complete heart block to "heal" itself? Should I request a consult with my cardiologist?
Avatar f tn PVCs and PACs occur when heart cells other than the typical pacemaker cells generate an electrical impulse and then a muscle contraction and heart beat. These may occur rarely or in some cases very frequently. Similarly, some people aren't aware of these while other people feel very symptomatic with them.
Avatar f tn Sick sinus syndrome and Norpace? I have had palpitations for years on and off but never were they captured on halter monitor or stress testing. They finally became bad enough that when I went to cardiologist office I went into a-fib and then back into NSR. I had an echocardiogram which they said was basically unchanged and showed good cardiac function. I had been placed on Topral approximately two weeks prior 25mg by my PCP due to mild HTN and c/o palpitations.
