ACLS Algorithms for Ventricular Arrhythmias

Quick fact

For every minute without defibrillation in VF, the chance of survival drops by about 7-10%.

Why this is interesting

You're in an emergency room when a patient collapses and goes into cardiac arrest. The monitor shows a chaotic squiggle—ventricular fibrillation. Do you shock first or start CPR? The answer is a race against time, and the ACLS algorithm is the map for that race.
