To explore short-term changes after left bundle branch pacing (LBBP) using echocardiography and computed tomography (CT), especially for postoperative ventricular septal perforation.Between January September 2019, 33 patients with atrioventricular block underwent LBBP at Beijing Anzhen Hospital. All the were evaluated electrocardiography, pacing, parameters echocardiographic measurements, including major complications, during 1, 3, 6, 12 24-month follow-up. Interval perforations examined a 1-month follow-up echocardiogram CT.Left was successfully performed in 100% (33/33) of patients. The mean seizure threshold stable unchanged postoperatively paced QRS duration 119.72 ± 2.53 ms <130 all Unipolar impedance procedure higher than 500 Ω (662.00 181.50 Ω). No perforation occurred end procedure. At follow-up, two reported transthoracic echocardiography, CT revealing lead perforation. Through CT, other found to have perforation, indicated that had penetrated interventricular septum entered subendocardium. these four exhibited no significant increase or (p > .05). thrombus stroke detected.Permanent is safe feasible bradycardia. Echocardiography and/or can more accurately evaluate cardiac structure function LBBP.
