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.
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.

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.
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.
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.
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.
Check out MaryLL's story on here. It should be posted in her journal. After 15 years of Afib, she was cured by having a thoracic maze procedure. They go in through the ribs and it is performed on a beating heart. She was having episodes every week. She had had 3 ablations before this procedure. It was a long recovery.
Also, Dr. Sirak at Ohio State University does a thoracic maze procedure and lots of people on here have posted that they were cured after the procedure.
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?
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?
There are several facts to be considered here. The longer the pacemaker stays in the body, the harder it is to take out. A pacemaker that has been inside for ten years is difficult to extract although not impossible. Once these devices get infected, it is very difficult to treat using antibiotics due the reason that you have mentioned. In that case scenario, the patient might require multiple courses of antibiotics or even sometimes life long suppressive antibiotics.
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.
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.
At the 6 week baseline check after the implantation, I was pacing 15% of the time for the atrium and 4 % of the time for the ventricle, with the threshold at 50 beats per minute.
At my most recent check in June; just under 6% Atrial and just over .2% Ventricular pacing.
An almost 13% reduction over 3 years.
The analysis I received is that the pacer gave my heart muscles and nerves a chance to heal and relearn their own job.
