what is shockable rhythm
INTRODUCTION The heart rhythms associated with cardiac arrest aredivided into two groups: 1. shockable rhythms â ventricular ï¬brillation andpulseless ventricular tachycardia (VF/VT) 2. non-shockable rhythms â asystole and pulselesselectrical activity (PEA). For shockable rhythms deï¬brillate and resumechest compressions (30:2) without re-assessingthe rhythm or feeling for a pulse for 2 minutesthen check rhythm, if VT/VT persists followALS algorithm. â For non-shockable rhythms start CPR at a ratioof 30:2 and give adrenaline 1mg as soon asintravascular access is achieved.
