SHORT COMMUNICATION
A tale of four atrioventricular intervals
Division of Electrophysiology, Department of Cardiology, Toronto General Hospital, University Health Network, 200 Elizabeth Street, Toronto, ON, Canada M5G 2C4
The introduction of new pacing algorithms for preserving intrinsic atrioventricular conduction has made the interpretation of normal pacemaker function at times challenging. Electrocardiographic (ECG) findings in a patient with apparent pacemaker malfunction is presented and interpretation given. During this process, the managed ventricular pacing algorithm is described to interpret the ECG findings and the potential pitfalls of this algorithm is discussed.
