title: Type A and ectopy in patients with coronary artery disease and controls.
abstract: The purpose of the current study was to determine if the Type A (coronary-prone) behavior pattern is associated with task-related ectopy either in patients with coronary artery disease or in controls. Two 10-min interviews related to heart disease and three performance tasks inducing different sympathetic and vagal responses were administered. The prevalence of ectopy was significantly higher in Type A volunteers, and was no different in coronary patients vs controls. Analyses of cardiovascular responses and patient characteristics failed to identify any other variable that separated Type As from Type Bs or those with ectopy from those without ectopy.
