ECG / Electrophysiology
Ventricular fibrillation is recognized on the electrocardiographic monitor as a highly disorganized rhythm with no definite P waves or QRS complexes.

ECG / Electrophysiology
Three or more ventricular complexes (wide QRS) occurring at a rate more than 100 per minute is taken as ventricular tachycardia (VT).

ECG / Electrophysiology
Accelerated idioventricular rhythm (AIVR) is a classical reperfusion arrhythmia which occurs during thrombolysis of acute myocardial infarction.

ECG / Electrophysiology
Three or more different morphologies of P waves, with a rate more than 100 per minute defines multifocal atrial tachycardia (MAT) or chaotic atrial rhythm.

ECG / Electrophysiology
Atrial fibrillation is the most common sustained arrhythmia and the incidence increases as the age advances.

ECG / Electrophysiology
Atrial flutter is usually associated with a fixed ratio AV block. If there is 1:1 conduction, the ventricular rates will be very high.

ECG / Electrophysiology
Supraventricular tachycardia (SVT) is identified as a narrow QRS tachycardia, often with barely discernible P waves.

ECG / Electrophysiology
Sinus tachycardia is secondary to a primary cause like fever, hyperthyroidism, heart failure, anxiety etc.

ECG / Electrophysiology
Ventricular asystole is manifested as total absence of electrical activity on the electrocardiogram and the person is in cardiac arrest.

ECG / Electrophysiology
Complete heart block or complete AV block is a situation in which the sinus impulses are not conducted to the ventricles through the AV node.
