Common Questions and Answers about Pacemaker cells differentiation

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.
However, the role of Th17 cells in persistent viral infection remains unknown. We report that Th17 cells preferentially develop in vitro and in vivo in an IL-6–dependent manner after Theiler’s murine encephalomyelitis virus infection. Th17 cells promote persistent viral infection and induce the pathogenesis of chronic demyelinating disease.
1. Blast cells are less than 3%. Plasma cells are less than 2%. No non-haematopoietic clump or haemoparasites identified in the slide examined.
BONE TREPHINE TOUCH PREP: Cellular smear showing same features as those of bone marrow aspirate.
BONE TREPHINE (H&E) SECTION:Good length specimen showing intact architecture and cellularity for age. Overall cellularity is around 45 to 50%. Cellular areas show presence of erythroid and myeloid precursors. Adequate megakaryocytes noted.
The pattern of growth is also somewhat different. If we are strictly talking about lung cancer, the differentiation is based on whether the cancer has small cell features. The origin is not really important in determining treatment options, and hence, there is no routine testing done to perform this function of differentiation. Stay positive.
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 differentiated action on unimpaired hepatocytes and resident macrophages (stimulation of metabolism, proliferation, and differentiation) and virus-infected cells (induction of apoptosis mechanism including due to expression of FasAg-CD95+ and Ras-signaling and p53-dependent apoptotic pathways in the virus-infected hepatocytes) is the basis for the mechanisms inhibiting the HBV and HCV replicative activity.

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.
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.
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.
A few patients successfully eliminate infection, thanks primarily to virus-fighting immune cells called CD8+ T cells. The protective effects of CD8+ T cells depend on a cellular protein called T-bet, which is needed for the production of antiviral molecules like interferon.
Scientists in Munich, Germany, have now found that high levels of T-bet in CD8+ T cells are prevalent in individuals who successfully fight off hepatitis infections but are virtually undetectable in those who don’t.
The retinoid, the chemical of accutane binds with certain receptors in the developing foetus, like the mesoderm ,effecting the terminal differentiation of cells leading to malformations.The effect on ectoderm ie skin is totally different.This difference makes the reason for different approaches which you have very rightly spotted.
Diagnosis says her body stopped producing NERVER GROWTH FACTOR cells from her 9th age.We met with many doctors in India and they said there is no treatment for this in India. She is 16 years old now. Very intelligent girl, her thinking,speech are very normal.Only thing is she is not able to walk and can not hold things in hand.Doctors comparing this problem with cancer since it has no treatment. Some doctors say the treatment is available in foreign countries like south Koria.
no parenchymal edema,mass effect,or midline shift. gray-white matter differentiation ispreserved .no evidence of intracranial hemorrhage. no intracranial mass or fluid collection.no hydrocephalus .corpus callosum pituitary gland ,and pineal region are unremarkable .prominent perivascular spaces within the bilateral inferior basal ganglia. expected major vascular flow voids are identified .visualized orbital contents and optic tract are unremarkable. paranasal sinuses are clear.
These were stem cells made from my OWN STEM CELLS not embryonic. So, no chance of rejection, no extra pills to take. There is over an 80% chance of
improvement. My EF was between 12 and 15% before new stem cells. Have not had another EF test yet. I am diabetic(insulin dependent.) I do have a defibrillator and pacemaker. Would be only too happy to share my experiences - they will be on-going!! It is a shame one has to go out of the country to have this procedure done.
There can be different reasons, but it generally finds a different way around, through normal heart cells. However, this can cause a delay, meaning the right chamber is contracting slower or is delayed compared to the left. This is probably what they are referring to with regards to borderline. Causes could be genetic history, certain infection types, recent heart attack, heart disease. If the cells are damaged, then there is always the option of a pacemaker.
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 father had a heart attack in 1984, a pacemaker four years ago andnow is diagnosed with heart failure, is this normal?
Hello, my father (early 60s) is on an ICD. His cardiologist wants to make the heart completely dependent upon the pacemaker, as the medicines my father is on aren't working. Unfortunately, I was unable to sit in on the meeting between my father and the cardiologist.
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?
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.
