ECG atlas of ventricular tachyarrhythmias in cardiac arrest

Sudden cardiac arrest is mostly heralded by ventricular tachyarrhythmias. This chapter presents the electrocardiographic (ECG) manifestations of ventricular ectopy, monomorphic ventricular tachycardia, polymorphic ventricular tachycardia, ventricular flutter, and ventricular fibrillation. Recognizing ventricular tachyarrhythmias is imperative due to their life-threatening nature. This chapter presents real cases (Greenwald et al), each accompanied by multiple, chronologically recorded, ECGs, in order to illustrate the electrocardiographic evolution of ventricular tachyarrhythmias.
