Synopsis

Electrical destabilization of the heart resulting in cardiac arrest. The ECG may show a rapid, grossly irregular QRS pattern with marked variability in cycle length, morphology, and amplitude. The rate is typically >300 beats/min. Ventricular fibrillation (VF) is the most common arrhythmia identified in cardiac arrest patients and leads to death within minutes if not promptly corrected.

Risk factors for VF are heart failure with ejection fraction <35%, coronary artery disease, previous myocardial infarction within the last 6 months, dilated cardiomyopathy, hypertrophic cardiomyopathy, or inotropic medications in patients with heart failure.

Presenting symptoms may be dizziness, shortness of breath, myocardial infarction, or sudden cardiac death.
