WebPremature atrial contractions (PACs) are common in children, and are defined as premature P waves with premature QRS complexes. There is an incomplete compensatory pause, making the premature beat less than two normal cycles. While most P waves have a subsequent QRS wave, rarely are PACs nonconducted. Webnoncompensatory pause: The interval on the electrocardiogram that follows a premature atrial contraction (PAC). Because PACs reset the sinus pacemaker, the next sinus beat …
WebIn such cases a compensatory pause creates conditions for PVC occurrence, and hence bigeminy persisting so long as the compensatory pause remains sufficiently long (see Figures 17-1 and 17-6). According to the rule, bigeminy disappears when the heart rate increases, which is usually the case ( Figure 17-9 ).
