Atrial Standstill & Idioventricular Rhythm

Report:

Sinus arrest (atrial standstill)

Idioventricular escape rhythm 10/min

Comment:

The amazing aspect of the patient’s extreme bradycardia was that she remained rousable with a pulse rate between 10 and 15/min in Casualty. Attempts to get all the 12 leads with QRS complexes on a single ECG failed (78a below). Without the clinical information, this trace could pass for an agonal rhythm.

The cause of the standstill was not found and she required a permanent pacemaker.
