Temporary atrial overdrive pacing is an effective and readily available treatment for drug-refractory electrical storm caused by bradycardia and R-on-T phenomenon following myocardial infarction.
Brady-dependent R-on-T may trigger refractory post-MI electrical storm; leaves open whether targeted pacing prevents recurrence.
A 64-year-old man with diabetes mellitus was diagnosed with a non-ST-segment elevation myocardial infarction and was treated with stent implantation. Four days later, he developed an electrical storm (ES) that persisted despite antiarrhythmic drugs and sedation. External defibrillation was performed more than 100 times over 2 hours. After ruling out the common causes of polymorphic ventricular tachycardia, an ES was considered because of brady-dependent R-on-T phenomenon, presumably precipitated by antiarrhythmic drugs. Temporary transvenous atrial overdrive pacing allowed complete suppression of premature ventricular complexes and ventricular fibrillation.

Chalupová et al. (2021) conducted a case report in Drug-refractory electrical storm in acute myocardial infarction (n=1). Temporary transvenous atrial overdrive pacing was evaluated on Suppression of premature ventricular complexes and ventricular fibrillation. Temporary transvenous atrial overdrive pacing completely suppressed premature ventricular complexes and ventricular fibrillation in a patient with drug-refractory electrical storm.
