Clinical use of atrial pacing test in angina pectoris.
Atrial pacing can be used as a safe test in the assessment of patients with angina pectoris. The results are useful in clinical judgements, and this method of investigation may be indicated for patients in whom the diagnosis of angina pectoris is in doubt or who are being considered for surgical treatment of ischaemic heart disease.
متن کاملComparison of atrial pacing and the cold pressor test in patients with angina pectoris.
A haemodynamic and myocardial metabolic study was performed to compare effects of maximal atrial pacing and the cold pressor test (CPT) in patients with angina pectoris. Twelve patients (group I) had angiographically severe coronary artery disease, while 16 patients (group II) had normal coronary angiograms. At maximal pacing, angina developed in all patients in group I, and myocardial lactate ...
متن کاملLeft heart hemodynamics during angina pectoris induced by atrial pacing.
In order to determine the associated hemodynamic events, angina pectoris was induced by an atrial pacing technic. In all patients developing angina pectoris, ischemic changes were noted electrocardiographically. The hemodynamic findings were variable: in some patients no changes were noted; in others, significant increases in cardiac output, left ventricular end-diastolic pressures (LVEDP), and...
متن کاملControlled heart rate by atrial pacing in angina pectoris. A determinant of electrocardiographic S-T depression.
SUMMARY This study was undertaken with a consideration of the physiological relationship between myocardial oxygen consumption and heart rate. Atrial pacing was performed in 63 resting subjects, 36 of whom had been referred for evaluation of angina pectoris. Pacing at critical controlled heart rates evoked angina pectoris in six patients of this group with chest pain and, consistently and more ...
متن کاملHaemodynamic comparisons of atrial pacing and exercise in patients with angina pectoris.
Though exercise is the most physiological test for angina pectoris, it has several disadvantages. The most important are that, it is difficult to achieve a steady state, comparable haemodynamic parameters are not readily reproducible during repeated periods of exercise (Burkart, Barold, and Sowton, 1967), it cannot be used effectively in patients with poor exercise tolerance, and angina pectori...
