This is a graphic from an @NEJM article which shows that Commotio cordis is when blunt trauma occurs during an appx 20msec Period during the T wave of the ekg causing degeneration into ventricular fibrillation-which is a fatal rhythm if not immediately defibrillated.
Congrats to my amazing mentors and attendings @HollandTamis and Dr Matthew Tomey on their huge contribution to this very helpful and needed scientific statement on the use of MCS in AMI with shock! https://t.co/YcVdslMKVw
