Abstract:
:Advanced or second-degree atrioventricular (AV) heart block pre-existing or developing during atrial pacing (AP) at low heart rates of smaller than 130 per minute, limits the value of AP to stress the left ventricle. When Wenkebach type AV block is present, the heart rate can be increased by administration of atropine before atrial pacing or by right ventricular pacing. Atropine, however, occasionally may cause serious supraventricular or ventricular arrhythmias, and high rate right ventricular pacing is not tolerated by many patients with left ventricular dysfunction because of the absence of the atrial contribution. Twenty-eight out of 101 patients with angina pectoris (27.7 percent) developed second degree AV heart block during atrial pacing studies performed for evaluation of left ventricular function. In 8 of the 28 patients, sequential AV pacing (SP) was performed successfully, with the heart rate being increased to 150-167 per minute. In 4 of the 8 patients, left ventricular dysnfunction was demonstrated during and immediately after SP. Typical angina pectoris developed in two of the four patients during SP, one of whom proved to have normal coronary arteriogram. Sequential AV pacing is an alternative method to increase the heart rate for the purpose of stressing the left ventricle when advanced degree or second-degree AV heart block pre-exists or develops during right atrial pacing. In some patients the method of SP might be preferable to administration of atropine or to ventricular pacing.
