WebAberrant conduction occurs when the length of the cardiac cycle is changed without a compensatory change in the length of the refractory period. This is explained by the changes of the refractoriness in the His-Purkinje system related to changes in the RR interval. Figure 1 shows a premature atrial beat causing aberrant ventricular conduction. WebTherein lies the distinction between a compensatory pause and a non-compensatory pause. Before we go any further, the concepts of (1) compensatory pauses, (2) non-compensatory pauses, and (3) interpolated beats (discussed later) are based on the actions of the SA node and consequently involve only P-P intervals.
