EP on EP Episode 98: PVC Cardiomyopathy 

This the most common sense discussion about PVC and cardiomyopathy I have heard. I would like to have you look at my case.

Could that sinus beat before the PVC represent a situation in which a "concealed" reentrant beat is emerging but never exits to a full-fledged complex but alters local mechanical function enough to manifest as partial dysynchrony? That seems more plausible than an autonomic influence fortuitously appearing immediately before the PVC.

Excellent commentary, Ed!
