The most common abnormal heart rhythm preceding cardiac arrest is ventricular fibrillation. In this dysrhythmia, the ventricular walls contract randomly and rapidly, and do not effectively pump blood.

The S-T interval represents the initial slow phase of ventricular repolarization. It is the time between completion of the QRS complex and beginning of the T-wave
