I don't know that one is treated as more critical than the other. Both are potentially life-threatening conditions. One in five people over 40 will develop heart failure (HF). That makes it a very common disease of aging, and as more people survive other events (e.g. MI), it will continue to be prevalent, if not to rise.[1][2] When a patient presents with ...

The His-Purkinje fiber system is a network of one type of specialized conducting cardiac cells that carry an action potential in the heart. There are other cells which perform this function in different parts of the heart. The initiation time, shape, and duration of the action potential are distinctive for different parts of the heart, reflecting their ...

On the wiki they are called cardiac action potentials. As the generation of the action potentials in the sinoatrial node is mediated by muscle cells, as is the conduction of the action potentials through the purkinje network (see wiki), the action potentials are not neural in nature, but cardiac.

Omega 3 Fatty Acids cannot prevent the the acute symptoms of periodic A Fib, nor is there a role for vitamin D in the treatment of acute symptoms of periodic AF. Atrial Fibrillation with the symptom of chest pain is very worrisome and requires urgent or emergent treatment. The most common treatments are heart rate control via IV antiarrhythmics, or ...

Good hypothesis is found in comment of inf3rno: A panic attack can lead to temporary asystole (if the patient have a heart disease) and after the heart attack s(he) is revived. This is the case if the patient has had myocardial infarction before and severe panic disorder. Consider now the case with panic disorder (no panic attack) where the data ...

Bradycardia is a heart rate under 60 beats per minute. Your strip shows a heart rate of ~54 BPM (so, yes, it's bradycardia), and the rhythm is trigeminy. There is no asystole involved. In the following rhythm strip, initially it shows supraventricular tachycardia (of >150 BPM). After adenosine administration, a short period of asystole occurs, allowing the ...

If there are no pacemaker cells active, no muscle contraction will occur. This condition is named asystole. It can be a temporary or definitive condition. Some would call it "extreme bradycardia" in temporary cases, but this is just an euphemism. Edit: Ok, so let's try to clear up the confusion a bit. Technically, there is no asystole involved here (not ...
