The 12-lead ECG suggested atrial flutter with a cycle length of 180 ms (330 cycles/min or 5.5 Hz) pattern in all the leads. With an intrinsic ventricular rate of 86 bpm, the initial machine-based assessment was atrial flutter with 4:1 AV conduction. Multiple ECGs were recorded ...

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 ...
Prolonged atrial conduction. A major predisposing factor for the development of atrial flutter. Electrophysiological studies were performed during sinus rhythm on 21 patients who had demonstrated the spontaneous occurrence of sustained atrial flutter...

136 patients were followed after implantation a pacemaker (PM) for a total of 1,919 patient-months (m = 14.1 months/patient). 22/136 patients had one or more episodes of atrial flutter or (AF) postoperatively. In 121/136 patients (group A) AF had not been documented before, in 4 it...
