PO-01-076 DIAGNOSIS OF CORONARY VASOSPASM PROMPTED BY EPISODIC ST ELEVATION ON A CONSUMER MOBILE ECG DEVICE

Mobile ECG-enabled devices are increasingly used by consumers with limited data on sensitivity to detect ischemic ECG changes. Coronary vasospasm is an important cause of sudden cardiac arrest. The aim this report present a case man who was determined have coronary resulting in ST elevation and VF. patient came medical attention after recording apparent consumer mobile device. N/A 64-year-old paroxysmal atrial fibrillation previously treated catheter ablation implantable loop recorder place. Two weeks prior his presentation our institution, he collapsed at church. He found be pulseless underwent bystander CPR. In-field revealed ventricular requiring defibrillation (Figure 1A). Subsequent inferior elevation. angiography demonstrated significant stenosis the left circumflex artery mild disease right artery. Percutaneous intervention performed drug eluting stent. prescribed aspirin, clopidogrel, metoprolol. Implantable cardioverter defibrillator placement deferred as arrest felt due acute syndrome revascularization. Over subsequent two weeks, reported episodic sensations chest uneasiness. recorded 6 lead AliveCor Kardia device baseline 1B) during symptoms 1C). Exercise treadmill stress testing no evidence ischemia. Due ongoing symptoms, presented institution. Baseline normal. On telemetry, dynamic changes were noted morphology matching tracing device, followed degeneration into nonsustained VF 1D-F). patent stent stable non-obstructive disease. Echocardiography Cardiac biomarkers A diagnosis made. managed amlodipine isosorbide mononitrate. After informed discussion, discharged wearable defibrillator. has not had any arrhythmias or follow-up. While typically diagnose arrhythmias, monitors may record electrocardiographic These assist vasospasm.
