Atrial Standstill & Idioventricular Rhythm
Report:
Sinus arrest (atrial standstill)
Idioventricular escape rhythm 10/min
Comment:
The amazing aspect of the patientâs 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.
