[Definitions of second degree atrioventricular block. An exercise in logic in clinical electrocardiography]
1Electrophysiologic Institute, Broward General Hospital, Fort Lauderdale, Floride, Etats-Unis.
Abstract:
Second degree atrioventricular block has received different definitions which make it difficult for physicians to interpret certain cases. This review of the literature provides an accurate definition of the criteria of Mobitz I and Mobitz II atrioventricular block, and proposes simple diagnostic methods based on conventional electrocardiography. The importance of the definitions is underlined and the consequences in terms of permanent cardiac pacing are emphasised.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
