Atrial flutter is a cardiac arrhythmia characterized by atrial rates of 240-400 beats/min, usually with some degree of atrioventricular (AV) node conduction block (eg, 2:1 or 3:1 block). Approximately 60% of patients with atrial flutter have coronary artery disease (CAD) or hypertensive ...

Atrial flutter with 1:1 atrioventricular response may be spontaneous or drug-induced and may occur in persons with or without known organic heart disease. The response is often caused by sympathetic discharge associated with exertion or excitement. The presence of wide QRS complexes due to aberrant...
Atrial capture is confirmed by: (1) an increase in heart rate as the pacing rate is increased; (2) a subsequent abrupt fall in heart rate as the AV conduction ratio increases (from 2:1 to 3:1 or 4:1); and (3) a constant relationship between the pacing spikes and the flutter ...
