Take Our Poll In HCM every myocyte is  genetically made  defective . Myofibrils are in disarray every where . Still , can we identify some vulnerable zones that acts as arrhythmic  focus ? If that is possible , we  have a opportunity to abate that focus . In HOCM  , which is the most stressed area ? LVOT ?  Septum, ? When we say stress , it can mean either mechanical or electrical .
