OBJECTIVE This study tested the hypothesis that coronary artery disease patients with higher depression scores have lower heart rate variability during daily life. METHOD Thirty-three men and nine women, ranging in age from 46 to 79, with coronary artery disease and exercise-induced ischemia were studied. The standard deviation of normal R-R intervals (SDNN) and average heart rate were obtained from 24-hour ambulatory electrocardiographic monitoring. Patients were grouped by a median split of… CONTINUE READING
