Cross talk is sensing of the far field signal, either the ventricular signal in the atrial circuit or atrial signal in the ventricular circuit. Usually it is the sensing of atrial signal in the ventricular channel. Cross talk detection in the ventricular channel can cause asystole. Following conditions predispose to cross talk inhibition of the [...]

Intrinsic deflection and intrinsicoid deflection Intrinsicoid deflection is recorded in the surface ECG and intrinsic deflection is recorded directly from the heart. Intrinsic deflection can be recorded in experimental settings or by the intracardiac electrodes in pacemakers. Ventricular blanking period Ventricular blanking period is the period after the atrial stimulus during which the ventricular sensing [...]
