Cyclic Nonrespiratory Pulse Pressure Oscillations Caused by Atrioventricular Dissociation

Figure 1

ECG, arterial pressure, and pulse pressure during pacemaker rhythm. The recording was taken shortly after the patient’s arrival to the ICU. Pacemaker spikes can be seen before every heartbeat, and the arterial pressure and pulse pressure indicate substantial fluctuations. The recordings were analyzed offline, and a pulse pressure diagram was also added.
