At present, there are only anecdotal reports of cardiac arrhythmias in space, including one documented episode of non-sustained ventricular tachycardia. (wikipedia.org)
The published report of non-sustained ventricular tachycardia during prolonged space flight supports this hypothesis, in that initiation of tachycardia by a late diastolic premature ventricular contraction (PVC) is more consistent with triggered activity than it is with re-entry. (wikipedia.org)
However, one crewmember experienced a 5-beat run of ventricular tachycardia during a lower-body negative pressure protocol, and another had periods of "wandering supraventricular pacemaker" during rest and following exercise. (wikipedia.org)
