Excerpt
A 68-year-old male patient was admitted with decompensated heart failure. He had undergone implantation of a cardiac resynchronization therapy pacemaker (CRT‑P; Quadra Allure MP™, Abott, Plymouth, MN, USA) 5 months previously in an external hospital due to intermittent second-degree atrioventricular (AV) block, prolonged PR interval and moderately reduced left ventricular ejection fraction. Postoperatively, the R‑wave amplitude sensed by the right ventricular lead was small; therefore, ventricular sensing was switched to the left ventricular lead. …
