Case Report

Profound Sinoatrial Arrest Associated with Ibrutinib

Figure 1

Telemetry recording from the time of syncopal event in our patient demonstrating sinoatrial arrest and a 26-second pause. Notice the absence of any atrial activity during the pause indicating this is sinus pause rather than AV block. The telemetry marks some tremor artifact during the event erroneously as atrial activity (A) which is another important finding to recognize.
