Holter ECG diagnosis of nicotine-spray induced ventricular fibrillation. An unusual case of Prinzmetal variant angina

We report on an interesting case of resuscitated sudden cardiac death (SDC) in a 51-year-old with hypertension and positive family history for SDC. The patient was resuscitated and an emergency angiogram ruled out coronary artery disease. Cardio-MRT ruled structural disease or infection. Holter and telemetry monitoring revealed premature ventricular complexes and transient ST-changes followed by anginaepisodes in correlation with the use of the nicotine-replacement-spray. The patient was urged to quit smoking and smoking-substitutes. Medical therapy with calcium-channelblocker and a long acting nitrate was administered. One-month follow up reported no arrhythmic or angina events.
