2.6 Data collection
Baseline patient characteristics, ECG features, and pacing indications were collected. After implantation final pacing thresholds, R‐wave sensing amplitudes, and lead impedances were measured during both uni‐ and bipolar pacing. The paced QRS duration and pLVAT were measured. Number of implantation attempts and fluoroscopy time were recorded. All patients underwent post-procedural transthoracic echocardiographic evaluation to assess potential LBBAP implantation‐related complications.
