Pacemaker cells calcium
Common Questions and Answers about Pacemaker cells calcium
pacemaker
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.
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.
In either case, the doctor will generally start with rate control -- with either a beta blocker or calcium channel blocker. I personally take cardizem (a calcium channel blocker), which brings my persistent afib into a heart rate range of 60-90. Verapimil sounds like a good choice for your wife. Cardizem works well for me and I hardly notice any symptoms (and so don't need to consider a pacemaker). There are those where this doesn't quite work like in your wife's case.
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.
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.
I suffer from permanent AFib, but I have no experience with a pacemaker. That said, I don't think there is anything a pacemaker can do about AFib. If you palpitations are irregular heart beats, and a heart rate that is higher than you would like, say over 100 bpm, it could be due some of to the AFib signals getting through. I take both a beta blocker and calcium channel blocker to reduce the number of extra heart beats I get from the AFib.
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.
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.
My husband , 61 years old, has a pacemaker and he suffers from severe leg cramps almost on a nightly basis. Is the pacemaker and leg cramps connected or could there be something else causng his leg cramps?

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.
hi i have had some private tests done and it has come back that i have verry high calcium in my blood cells and was wondering what this could mean?! the doctor told me that it was becouse of low magneseum levels but a friend doctor seems to think he may be going down the wrong root, and may be a diffrent matter. i have been treated for graves disease and have taken the radiocative iodine could this have anything to do with it?
It apparently enhances the binding of the protein calstabin-2 to a calcium channel present in heart cells, thereby stabilizing the channel in its closed state and preventing potentially dangerous calcium Leakage? Does CHOP have many CPVT patients? Thank you in advance for advice/direction and I look forward to your response.
m a 22 years old male and had problems with urinating too much, recently had a blood test and everything is fine (thyroid, liver enzyme, albumin, red cells, white cells, etc ...) but my calcium level is : 103 mg/L (range is 86 to 100)
Do you think I should ask my doctor to check my PTH?
I've also seen on the internet it also could be advanced cancer causing elevated calcium ...
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.
My father is 69 years old had a stroke 12 years ago, had pacemaker installed about 8 years ago, he has had a couple heart attacks. he also has congestive heart failure and is always in atrial fib. His heart is now working at 15 percent. i was wondering if there is any medication or what can be done to have his heart pump stronger so he doesnt continue to build fluid in his body. He currently takes lasix, aldactone and coumadin.
I started having arrythimias according to a pacemaker check. Could this medication cause all of this to happen. Plus a paid mgmt dr put me on a strong muscle relaxer years before this and my heart beat dropped to 40 beats and this caused me to have the pacemaker. I sleep walk a lot and sometimes find some of my meds are gone and this occasion sev muscle relaxers weren't in the bottle. I might be in denial and just have heart failure.
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.
If you don’t have enough magnesium to help keep calcium dissolved, you may end up with calcium-excess muscle spasms, fibromyalgia, hardening of the arteries, and even dental cavities. Another scenario plays out in the kidneys. If there is too much calcium in the kidneys and not enough magnesium to dissolve it, you can get kidney stones.”

his can go over 200 and down to 58 with out any issues (scares me as he might stroke out) a few weeks ago he went from 110 (normal down to 48 and passed out. he just bought himself a pacemaker his cardiologist said. he did wear a holter monitor also for 24 hours. it showed a hr of 48 while he was a sleep, DR wasn't concerned. and the highest was 174 at rest.
I have AFib, an implanted defibrillator/pacemaker and two stents after a major heart attack and SCD.
Your question involves electrophysiological/chemical (electrolytes) phenomonon that polarizes (charging...chamber filling), and repolarization (discharging...contractility of chamber) heart cells. In arterial smooth muscle cells, intracellular calcium paradoxically controls both contraction and relaxation.... The mechanisms by which calcium can differentially regulate diverse physiological responses within a single cell remain unresolved....
