Electrical injury-triggered ventricular arrhythmia in a patient with a pacemaker: highlighting the importance of cardiac monitoring.

A 46-year-old man with a history of Hodgkin lymphoma treated with chemotherapy and radiotherapy in 2003 had dual-chamber pacemaker implantation in December 2018, for recurrent episodes of syncope with documented paroxysmal complete atrioventricular block. Left ventricular ejection fraction was normal, and no other anomaly was observed on echocardiography. One month after pacemaker implantation, the patient presented with an electrical shock while using his hairdryer followed by a brief loss of consciousness. He immediately stopped using his hairdryer but did not seek urgent medical attention and had a pacemaker interrogation 3 weeks later. Multiple episodes (n1⁄4 16) of non-sustained polymorphic ventricular tachycardia were recorded by the pacemaker in the hours following electrical injury (Figure 1A), the last one occurring 4 h after the event. The duration of the longest episode was 7 s, with the shortest cycle length around 200 ms (300 b.p.m.) that terminated spontaneously (Figure 1B). After discussion, considering that these episodes were most likely triggered by the electrical injury, a course of simple surveillance with telemonitoring was decided upon. After 1 year of followup, the patient had no recurrence of arrhythmia. In apparently healthy patients after electrical injuries, the main feared risk, albeit rare, is sudden death. This case perfectly illustrates how electrical injuries may trigger potentially life-threatening ventricular arrhythmias with a clear
