A female patient in her seventies was admitted to the cardiac monitoring unit following an episode of abdominal pain and hyponatraemia. She has a history of paroxysmal atrial fibrillation and recently diagnosed severe left ventricular systolic impairment. A dual-chamber pacemaker was implanted for tachy-brady syndrome in 2017.
An inpatient pacemaker interrogation was requested to assess for arrhythmia. All lead and battery measurements were satisfactory.
One ventricular tachycardia (VT) episode was detected by the device lasting for 13 minutes. The EGM for this episode is seen below (Figure 1):
