A distinction is made between the cause of the “twisting of the points” and the cause of the action potentials that initiate and sustain the tachycardia. It is pointed out that torsades de pointes and other pause-induced arrhythmias share many features with rhythmic activity arising from early afterdepolarizations. Both are seen after pauses or… CONTINUE READING
