Common Questions and Answers about Pacemaker cells heart rate

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.
After heart attacks, I had to be on carvedilol to allow my heart to try and establish new little arteries and to repair stunned heart cells. I had to have a pacemaker inserted to keep me from passing out because of the drug but also because my heart rate would race at rest, sometimes over 200bpm. You might ask your doctor if you could take a more gentle control of blood pressure. carvedilol can be the cause of breathlessness.
Hello. Usually the heart rate would increase when a fever is present. If a patient has Sick Sinus Syndrome where the heart rate cannot increase because the sinus node is "sick" then a pacemaker is implanted and a range of, usually, 60-100 beats per minute is set. If this person's heart rate cannot increase ON IT'S OWN and their pacemaker is set at a low rate of 70 beats per minute, the fever will not cause the heart rate to go up because it can't.
my husband has been in and out of the hospital for the last year and 1/2 due to his heart. His heart rate is 25 had a pacemaker put in and has been seeing his heart dr for years now. his last visit to the hospital docyor said he didnt know what else he could do, that he was on tthe best meds that he could give him.
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.

The average Heart rate was 70 BPM . The minimum heart rate was 57 BPM . The maximum heart rate was 97 BPM.
Ventricular ectopic activity consisted of 16 beats of which 12 were in single PVCs 2 were in interpolated PVCs, 2 were in R on T.
The patient's rhythm included 1 hr 32 min 28 sec of bradycardia. the slowest single episode of bradycardia occurred at 10:07:27 PM , lasting 1 min 23 sec , with minimum heart rate of 57 BPM.
How do you know that you have low heart rate before you wear the holter monitor? What type of problem you noticed before you realize this problem? Usually younger and more active person experience low heart rate at rest.
Scar tissue from a previous heart attack may be an issue if the stress test shows
ischemia (lack of blood flow) of the subject area if the perfusion exists for both stress mode and rest. This would indicate necrotic heart cells as the dead tissue would not function with or without stress. If your ejection fraction (normal 50 to 70%) is within the normal range you probably don't have any damaged heart cells. EF is the amount of blood pumped with each heartbeat.
i was advised to take meds to bridge the slow heart rate. i was told about the sick sinus, that causes slow heart rate. lowest rate is 49beats/minute highest i got was 63. i don't have a heart failure. and yes i believe this is one of the greatest decision i will make in my life.. i know once i put this, i will be needing a replacement in 10 years or if needed as per doctor's advise.
In response to your comments on your other post.
The Human body is a great design and has more than one system to increase oxygen. When we are at rest, around 98% of Haemoglobin will be saturated with Oxygen, and the body only uses around 20-25% of this which leaves a LOT in reserve. If the body starts to use more and levels start to drop, we produce more Haemoglobin in bone marrow and send it into the blood stream, giving a higher saturation.
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.
Your basic heart rate is set by a specialized region of the heart called the 'Pacemaker.' Many cardiac muscle cells can contract spontaneously, but the cells in the Pacemaker region are, during fetal development, the fastest-beating ones, and the fastest ones normally dominate the whole show.
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.
It's it's symptomatic, a pacemaker is the only option. If it's not symptomatic, don't worry about.
no. 84 is not high, it's only generally if it gets to over 100 at rest that tachycardia is diagnosed. As long as his heart rate is stable and there are no rhythm problems, then there is certainly no requirement for a pacemaker.
m curious is that people that have demand pacemakers will have their heart rate maintained at a certain point if their heart rate drops too low. Taking too much of a Beta Blocker can drop your heart rate, with a demand pacemaker, it would be assured to be maintained at a certain rate. Also, your doctor may have choosen your dosage based on your conditions, not simply rate control, I would discuss this with your doctor.
I had hypokinesis and the problem was a lack of sufficient blood flow to the heart wall and that portion had some heart wall movement impairment. Often the heart cells are in hibernation and when supplied with good blood supply are revitalized as what happened in my condition. As stated by jrbon, the doctor it is highly probable there is ischemia (lack of blood flow).
You should not wait for something to happen, and As I stated in a previous post there can be ischemia without any symtoms.
You have Afib and Aflutter which means that the Atria (small chambers at the top of the heart) are not beating normally. Medication can usually resolve this problem. Severe brady just means your heart rate is very slow. A pacemaker could be a good solution to this. If you have one, then this will need to be adjusted or upgraded. You also have 'unstable' angina which means that you feel symptoms unassociated with CAD. Now the severe aortic stenosis.
My daughter was diagnosed with a variety of heart problem when she was two months old. She currently has a pacemaker which she only uses when her heart rate goes above 115 bpm. When she has surgery 7 years ago the surgeon lost a surgical needle in the center (av node) area of her heart. Could the needle be the reason she is having heart block? She is ten now.
