What is this heart rhythm? a. ventricular fibrillation b. torsade de p. c. asystolie d. atrial fibrillation

Answer is A. This is stereotypical ventricular fibrillation.

TdP can degenerate into VF but it usually appears as more of a polymorphic VT with discrete QRS waves pointing in both directions.

Asystole refers to cessation of heart muscle contraction. If the ECG flatlines there is likely asystole.

In atrial fibrillation you would see discrete but irregular QRS complexes separated by a wavy baseline where it would be difficult to make out P waves.

The links within this chain of survival include: early access to the emergency response system. early cpr to support circulation to the heart and brain until normal heart activity is restored; early defibrillation to treat cardiac arrest.
