A Case of Transient ST Elevation and Polymorphic Tachycardia without Angina Diagnosed by Holter Monitoring.

We report the case of 52-year-old female with recurrent episodes of palpitations and dizziness. Holter monitoring revealed transient ST elevations followed by episodes of polymorphic ventricular tachycardia associated with episodes of palpitations and dizziness. Coronary angiography revealed mildly irregular right coronary artery with 90% stenosis. The patient underwent percutaneous coronary intervention with successful placement of a stent to the mid-right coronary artery. The patient has been followed closely over a period of 12 months. There haven't been any recorded episodes of tachycardia, and the patient has remained symptom-free.
