Paced QRS morphology mimicking complete left bundle branch block induced by right ventricular pacing is associated with pacing ‐induced cardiomyopathy
ConclusionCLBBB-like paced QRS may be a novel risk factor for PICM. RV pacing, which causes CLBBB-like QRS morphology, may need to be avoided, and patients with CLBBB-like paced QRS should be followed-up carefully. (Source: Journal of Cardiovascular Electrophysiology)

Nonclinical evaluation of chronic cardiac contractility modulation on 3D human engineered cardiac tissues
ConclusionThese data represent the first study of chronic CCM in a 3D ECT model, providing a nonclinical tool to assess the effects of cardiac electrophysiology medical device signals complementing in vivo animal studies. The methodology established a standardized 3D ECT-based in vitro testbed for chronic CCM, allowing evaluation of physiological and molecular effects on human cardiac tissues.

Comparison of clinical outcomes between transthoracic echocardiography ‐ and X‐ray‐guided left bundle branch pacing for bradycardia: A randomized controlled trial
ConclusionTTE-guided LBBP is a feasible and safe method. Compared with X-ray, TTE showed a comparable success rate and procedure time, but it could significantly reduce the fluoroscopy time of LBBP. (Source: Journal of Cardiovascular Electrophysiology)

Data ‐driven classification of left atrial morphology and its predictive impact on atrial fibrillation catheter ablation
ConclusionsOur study illustrated the feasibility of employing unsupervised learning for the classification of LA morphology. By utilizing morphological grouping, we can effectively identify individuals at different risks of postablative recurrence and thereby assist in clinical decision-making.

Delivery catheter system carries more physiological right ventricular septal pacing than stylet system
ConclusionUsing a delivery catheter system carries more physiological depolarization and repolarization during RVS pacing and deeper screw penetration in the septum in comparison to conventional stylet system. The lead depth could have a more impact on the ECG parameters rather than the type of pacing lead. (Source: Journal of Cardiovascular Electrophysiology)

The impact of supraventricular arrhythmias on the outcomes of guideline ‐compliant implantable cardioverter defibrillator programming
ConclusionProgramming ICDs in primary prevention patients based on current guidelines reduces therapy burden without increasing mortality in both SVA and non-SVA patients. A greater magnitude of reduced ICD therapy was found in those with supraventricular arrhythmias. (Source: Journal of Cardiovascular Electrophysiology)
