| atrial septal d.’s |
congenital cardiac anomalies in which there is persistent patency of the atrial septum due to failure of fusion between either the septum secundum or the septum primum and the endocardial cushions. In ostium secundum d. there is a rim of septum all around the defect. In ostium primum d., which is an incomplete form of atrioventricularis communis, there is no septum at the base of the defect, between the mitral and tricuspid valves; it is usually associated with a cleft mitral cusp and occasionally with a cleft tricuspid valve or a ventricular septal defect.

| atrial synchronous ventricular p. |
a dual chamber cardiac pacemaker that senses atrial activity and delivers a ventricular stimulus after a preset interval; used in patients with impaired atrioventricular conduction but normal sinus node function. Called also VAT p. See also atrial synchronous ventricular inhibited p.

| atrial t. |
a rapid cardiac rate, usually between 160 and 190 beats per minute, originating from an atrial locus; it may result from enhanced automaticity or impulse reentry.
