The electrocardiogram ( ECG ) interpretation in patients with cardiac resynchronization therapy ( CRT ) is often a perplexing problem. The difficulty in the device evaluation increases in the presence of unfamiliar timing cycles and a lead dysfunction. Authors describe a special function of a Biotronik CRT devices called the left ventricle T‐wave protection ( LVTP ), and demonstrate its behavior in a patient with left ventricular ( LV ) lead failure. This report shows that sometimes it might be difficult to understand the loss of resynchronization in 12‐lead ECG when LVTP feature is on, and a malfunction of left ventricular lead sensing occurs.
