Pacemaker cells part
Common Questions and Answers about Pacemaker cells part
pacemaker
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.

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.
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.
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.
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.
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.
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.
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.
from that blood draw my own stem cells were replicated. 23 Million Stem Cells were injected into my heart muscle and vascular system - via an angiogram. 80% of those 23 million were tagged for my heart. I will be glad to put you in touch with the Heart Clinic, in Florida, that I used. The procedure is not covered by insurance - again because of lack of FDA approval. Testing is being done in the U.S. in Chicago and Texas - might be elsewhere that's the 2 I know.
As a heart patient I think Coreg did indeed revive the heart stunned heart cells. Dead cells are just dead, but some of the cells can be revived, I was told.
I weigh 85 pounds more than you and know that drug doses are given by body weight in many cases. I'm a big believer in quality of life as opposed to just staying alive, so know your struggle, I had it for several months. Easy for me to say, but I'd stay the course until you just can't endure the fatigue.
when both the sa and av nodes have been ablated, wouldn't it be cause for both pm & icd? I thought that one was the heart's natural pacemaker for the top part of the heart and the other was for the lower part? which is where my thought was leading to with both pm & icd if both had been ablated and 100% pacemaker dependent
"Ventricles alone can sustain life, as proven by folks that are in a-fib" is that the same as in Vfib?
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.
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.
hi, finally the doctor said i should go for a pacemaker dual chamber as my heart is missing beats and slow. can those who already went for this type of operation share their experience with me please. and can you tell me if it does cost a lot, is there any complication after operation? is there any thing i should know? will my life be back to normal? as now i can't even work!!!
phenomenon can occur if a part of the heart is wounded by MI, myocarditis, cardiomyopathy, etc. because the wounded area conducts electricity slow and by the time the impulse has travelled throug the area, the origin spot is able to conduct electricity again (cells are recharged). It is possibly dangerous, and the main reason why PVCs are usually suppressed with medications if someone have an "underlying heart disease" (as mentioned above).
the cardoligst said the bottom part of his heart is working, but the top part is not. reccommend pacemaker.
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.
my father had a heart attack in 1984, a pacemaker four years ago andnow is diagnosed with heart failure, is this normal?
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?
