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 ...

You wouldn't normally apply the stimuli simultaneously. The idea is to apply stimulus1, which has a given amplitude and duration, and follow that with stimulus2, which also has a given amplitude and duration, after a variable lag. You'll then see that the effective refractory period is dependent on the amplitude of stimulus2 (at least until you hit the ...

As another answer suggested, it's a matter of choosing a database that has all of the leads. The St Petersburg INCART 12-lead Arrhythmia Database (incartdb) contains all 12 signals. Here is the directory. The tracings are available by selecting it from the drop-down menu on the page you linked.

I don't think that all leads are available. I looked at the Signals combobox for different databases. This combobox seems to be the list of all available leads. For example, take a look at iafdb (Intracardiac Atrial Fibrillation Database). It will plot you an ECG containing leads II, V1 and aVF and some other leads. Another example is the EEG database ...
