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.

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.

I had a halter monitor test done by my PCP and they said they recorded several pauses. One that was 9.5 seconds, one 6 seconds and two 3 seconds. I was referred to a cardiologist who recommended a pacemaker. What are the odds that in that 24 hour halter test there are 4 pauses but now my pacemaker has not recorded any in an 8 month period? I also did not have tachycardia until after the pacemaker implantation.

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.

They are basically destroying cells which are messing up the signal for heart rhythm and so there is a risk they could stop the heart or send it into VF. Even after bypass surgery they attach a wire to the heart, which protrudes from the chest, in case they need to attach a pacemaker. It's better to be ready for any situation rather than waiting to get the equipment connected to you.

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.

It's interesting that everyone has irregular beats--but most people simply don't feel them. We sensitive types do. Perhaps you've read what actually happens during an ectopic beat? If not, here's a simplified rundown: The 'Pacemaker' in the upper right atrium normally sets the heart rate, but it's important to know that every cardiac cell in the heart is naturally rhythmic and contractile.

When I was at the doctors office they explained that it is working everytime her heart beats. They told us that the lower right side of her heart is bad. They said the pacemaker is set at 60bpm to keep her heart at a steady beat but when her blood pressure is taken the lower number is always in the 80's. I tryed to ask could the pacemaker be set to high for her body.

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.

When I do any exercise that really contracts the muscle that my pacemaker lies under, I pay attention to how it feels and stop or switch positions if it feels like it is putting too much pressure on the pacemaker. If your pacemaker has been implanted recently, be especially careful for the first few months while the scar tissue grows to hold the pacer and leads in place.

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.

Mainly, you need to talk to your doctor about this. Herbs and supplements are not regulated by the FDA and, given the recent news that some things that ARE regulated by the FDA aren't so well regulated, I'm always nervous about completely UNREGULATED products. I took Norpace for awhile. It is a heavy duty antiarhytmetic that suppresses the sodium and potassium channels causing the pacemaker cells to fire more "regularly.

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.

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.

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.

Hi I'm 13 and 5 months ago I got an attack in the back of the head that felt like I was super drunk going in circles, I don't know how to explain it because that has never happend to me. The next day and for the nxt month I was so dizzy and nauseated like if I just gone riding a rollercoaster 1000 times . I went to the doctor and he gave me pills that refuce thebad feeling but now the dizzy an nausea feeling stayed with me but the dizzyness is located in the back of the head.

On July 9 of this year, I was implanted with a pacemaker and now am a card carrying member of the Pacemaker club. The reason, complete or phase 4 heart block with bradycardia. Before the implantation, I was monitoring my blood pressure on my own with a home monitor. I am also a trained nurse. I noticed that I was having palpitations, quite regularly, and my blood pressure was averaging 160/100 where it used to be 112/80. My heart rate, resting, was averaging 100 bpm.

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.

Hello. Welcome to the MedHelp MS Forum. I don't know off hand about the location of lesions in that part of the brain, but I found this: "The basal ganglia refers to large clusters of nerve cells which are located within the cerebrum and upper parts of the brain stem. These structures help start and stop movement, as well as keep movements smooth and fluid.
