Popis: Abstract Objective To explore short‐term changes after left bundle branch pacing (LBBP) using echocardiography and computed tomography (CT), especially for postoperative ventricular septal perforation. Methods Between January and September 2019, 33 patients with atrioventricular block underwent LBBP at Beijing Anzhen Hospital. All the patients were evaluated using electrocardiography, pacing, parameters and echocardiographic measurements, including for major complications, during the 1, 3, 6, 12 and 24‐month follow‐up. Interval perforations were examined during a 1‐month follow‐up echocardiogram and CT. Results Left bundle branch pacing was successfully performed in 100% (33/33) of patients. The mean seizure threshold was stable and unchanged postoperatively at the 1, 3, 6, 12 and 24‐month follow‐up. The paced QRS duration of the LBBP was 119.72 ± 2.53 ms and .05). No ventricular thrombus or stroke was detected. Conclusion Permanent LBBP is safe and feasible in patients with bradycardia. Echocardiography and/or CT can more accurately evaluate changes in cardiac structure and function after LBBP.
