Insights

Left bundle branch area pacing (LBBAP) shows better lead performance and procedural outcomes compared to His bundle pacing (HBP) in patients needing atrioventricular node ablation (AVNA). Further research is needed due to limited evidence.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Devices

Background:

  • Atrioventricular node ablation (AVNA) necessitates permanent pacing, highlighting the importance of lead performance and procedural durability.
  • His bundle pacing (HBP) and left bundle branch area pacing (LBBAP) are advanced physiologic pacing strategies for AVNA patients.
  • Comparative evidence between HBP and LBBAP in this context is currently limited.

Purpose of the Study:

  • To systematically review and compare the lead-related and procedural outcomes of HBP versus LBBAP in adults undergoing AVNA.
  • To assess chronic lead-related dysfunction, procedural duration, and atrioventricular nodal reconduction rates between the two pacing strategies.

Main Methods:

  • A systematic literature search was conducted on PubMed/MEDLINE and Embase up to January 31, 2026.
  • Included were comparative studies of HBP versus LBBAP in adult AVNA patients.
  • Random-effects models were used to pool data for primary (lead dysfunction) and secondary (procedural duration, reconduction) outcomes, with certainty assessed by GRADE.

Main Results:

  • Three observational studies (434 patients) were included.
  • Left bundle branch area pacing (LBBAP) was associated with significantly lower rates of chronic lead-related dysfunction (RR 15.43) and atrioventricular nodal reconduction (RR 19.34) compared to His bundle pacing (HBP).
  • His bundle pacing (HBP) procedures were longer (MD 11.33 min), with very low certainty for lead dysfunction and reconduction outcomes.

Conclusions:

  • Left bundle branch area pacing (LBBAP) demonstrates more favorable lead-related and procedural outcomes than His bundle pacing (HBP) in patients undergoing AVNA, based on available observational data.
  • The current evidence is limited by small cohorts, sparse events, and nonrandomized designs.
  • Findings are considered hypothesis-generating and warrant further investigation through robust clinical trials.

Dysrhythmias IV: Characteristics of Bradyarrhythmias

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Conduction System of the Heart

Autorhythmicity is a term that refers to the heart's inherent ability to generate electrical signals and instigate muscle contractions. This self-regulating conduction system within the heart consists of two key components: the pacemaker cells and specialized conducting cells.
The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...

Dysrhythmias VI: Management of Dysrhythmias

Dysrhythmia management involves a multifaceted approach, incorporating pharmacological treatments, medical procedures, surgical interventions, lifestyle modifications, and patient education.Pharmacological ManagementAntiarrhythmic Drugs:Class I (Sodium Channel Blockers): This class includes quinidine and procainamide, which reduce the speed of impulse conduction in the heart, stabilize the cardiac membrane, and control arrhythmias. Quinidine and procainamide are Class IA agents that prolong the...
