Primary pacemaker cells of the heart
Common Questions and Answers about Primary pacemaker cells of the heart

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.
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? I'm trying to research this procedure, and specifically, gain a clear understanding of the associated risks (along with mortality data), both immediate and long-term.
I thank you in advance for any guidance you can provide.
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. But, if a particular group of cells in areas remote from the SA node become extra- or hyper-excitable they can take over as the pacemaker for one or several beats, or for a longer term.
You might think of the heart's cells as a schoolyard full of young boys playing soccer.
When the electrical system in your heart goes a bit haywire (like a blown fuse or a power surge) then the cells in the heart can react by causing a premature heart beat.
Premature beats of the ventricles or atria are not (in themselves) dangerous and rarely cause any further complications. However, since your heart has been given an artificial pacemaker for whatever reason, it stands that your electrical system is likely not functioning properly.
Potassium is a chemical element and it is part of the electrolyte that should be in balance with other lytes to adequately conduct an electrical impulse that originates with the sinus node in the right atrium. The mechanism of action is not completely understood, but what is when a voltage (unit of potential for conduction) and electrolyte there will conduction and passage of electrical impluses.
My husband has a family history of heart problems (aunt has a pacemaker, uncle had heart surgery at an early age, father has arrythmia & extra tissue on his heart). He enjoys long distance running (up to 25 miles a week) & had a strange experience the other day (he went to his knees when he experience what he described as an earthquake go back & forth across his chest, nausea & dizziness). Should he see a cardiologist or go to his primary care physician? thank you.
Alcohol may trigger an irregular beat by changing the chemical structure of the cells in the heart. Thus it is the chemicals that really cause the extra beats. All these drugs change the way cells emit and take in chemicals (potassium, etc). In this way it is intented that all the cells become synchronized--thus no irregular beats.
Thus the real cause is that cells develop the propensity for irregularity, and no one knows why this happens.
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.
This goes all the way down to the bottom of the heart. The front of the left ventricle has a small part that is also receiving less oxygen. Diminished means less or smaller, so unless they've used the wrong terminology, I would suspect the heart muscle is alive but not receiving enough oxygen for exertion. If that amount was scar tissue, I would suspect you would be experiencing all kinds of serious health issues.
s nearly 30 years ago and I think heart failure would have begun years ago from that. What you need to establish is the cause of the heart failure. Have there been more blockages in the arteries that haven't been treated? was there as infection involved? I get the impression that artery blockages have been the cause, hence the pacemaker requirement because the normal cells transmitting the signal have been killed. The question would be, why didn't they treat those blockages?
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.
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.
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?
When you have a PVC, the rebel cells cause the ventricle to contract earlier than usual. Because of the way the heart fills, this means the ventricle has not had the opportunity to get as full as usual, and as a result, this particular contraction is weak, as in *really tiny.* People don't usually feel it at all.
d suppose that they hope/expect some cells stick there in the heart and then do their magic. The cells can be gotten from such places as the marrow (naturally, because of the hematopoeitic stem cells used in blood cancer therapy), but also from fat or muscle areas.
There is a presentation that was given at Hypertension2008 in Berlin this past summer, on the same topic, which stated that this approach is used more post-MI than in HF. They had some dramatic results in that setting, too.
My wife had a pacemaker installed last April to control Atrail Fibrillation. She also had an abration process to make her pacemaker dependent. She has progressively had extreme fatigue to the point that she is not able to walk very far without resting, nor exercise at all. She has had banks of tests including blood, adrenal, nuclear stress test, etc., and all were in the "normal" range.
t help anything. It just makes us miserable. You take care of what you can, let the doctors take care of what they can, and try to roll with the punches, so to speak. Maybe you will (or won't) need a pacemaker someday, and if that's the hand you're dealt, there's nothing to be gained by worrying about it until that day comes. I'm not sure what your dad's problem is when you say severe exactly, but a pacemaker really is not that big a deal, in the grand scheme of things.
