Abstract:
We present the case of a 46-year old male patient suffering from non-ischemic cardiomyopathy and intermittent atrial tachycardia. According to guidelines an implantable cardioverter defibrillator (ICD) was planned to implant through the left subclavian vein. During the procedure the angiography revealed a persistent left superior vena cava (PLSVC) with moderate stenosis of the subclavian vein. Due to this we decided not to implant a dual chamber ICD but to implant a single chamber lead with additional atrial sensing capacity. The procedure as well as the follow-up was uneventful. Follow-up revealed good ventricular as well as atrial signals.

01:28Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
