title: [Atrial pacing in the evaluation of coronary disease].
abstract: In order to assess the value of atrial pacing in the diagnosis of myocardial ischemia, 23 patients (mean age 53 +/- 8 years), submitted to coronary angiography, were studied. Atrial Pacing at incremental frequencies was performed until the appearance of electrocardiographic changes (ST segment depression) and/or typical anginal pain. The highest frequency of stimulation was 160/min. The test was negative in four of five patients (80%) without significant obstructive coronary artery disease. Atrial pacing test was positive in 17 of 18 patients (94%) with abnormal angiography. The authors concluded that clinical and ECG abnormalities induced by atrial pacing seems to be correct indicators for the diagnosis of myocardial ischemia. This test can be an useful alternative in patients unable to perform a conclusive stress test.
