Cyclic Nonrespiratory Pulse Pressure Oscillations Caused by Atrioventricular Dissociation

Figure 2

Relationship of sinus and paced cardiac activity and its effect on arterial pressure. The ECG strip shows a paced ventricular “regular” rhythm, where atrioventricular dissociation is still present. The small arrows indicate atrial activity (“A”). The coincidence of normal AV sequence results in substantial arterial pressure augmentation (indicated by the thick arrows).
