Torsade is a fairly rare arrhythmia caused by a long QT syndrome usually due to electrolyte imbalance or medications although it can be hereditary. It would not be the usual arrhythmia in myocarditis. Truth is we have no idea what he died of and anything posted here is tank speculation unless and until an autopsy is done and this man’s medical history is known
I won’t argue with waiting for the autopsy ;-) though it will be interesting what the result would be, and more significantly if it will be reported honestly.
