Maintenance of AV synchrony in a small child utilizing two pacemakers and the triggered VVT mode: triggered pacing in small children.

Infants and small children with atrioventricular (AV) nodal disease frequently require pacing in order to maintain an adequate heart rate. The maintenance of AV synchrony is physiologically optimal in this setting. Unfortunately, small size and congenital anomalies often preclude the placement of standard transvenous dual chamber pacing systems.
