Abstract:
We present a 59 year old patient with advanced heart failure who underwent lead extraction. The lead was implanted 11 years ago, and 2 years later looped spontaneously following its fracture. The transvenous extraction process through inferior vena cava was complicated by knotting of the inactive lead over the active ventricular lead. The patient was pacemaker-dependent. Finally, the old lead was successfuly explanted. The active intact lead was used to create resynchronisation system.

Electrocardiogram 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.
