Overview

Ventricular tachycardia must be distinguished from a variety of electrocardiographic abnormalities with similar appearance.

Differentiating Ventricular Tachycardia from other Disorders

• Accelerated idioventricular rhythm
• Atrial fibrillation
• Atrial flutter
• Atrial tachycardia
• Congestive Heart Failure and Pulmonary edema
• Dual-chamber pacemaker tracking an atrial tachycardia
• ECG artifact
• Hypocalcemia
• Hypokalemia
• Hypomagnesemia
• Inappropriate rate responsive pacing
• Long QT syndrome
• Multifocal atrial tachycardia
• Myocardial infarction
• Pacemaker failure
• Pacemaker syndrome
• Paroxysmal supraventricular tachycardia
• Premature ventricular contraction
• Pulseless electrical activity or PEA
• Sudden cardiac death
• Supraventricular tachycardia, atrial tachycardia (SVT, AT) with aberrant conduction
• Ventricular fibrillation
• Wolff-Parkinson-White syndrome
