Arrhythmias & electrophysiology
Anatomical approach to suppression of para-Hisian ventricular arrhythmias with changes in QRS morphology after ablation at the earliest activation site
Authors' conclusion
The anatomical approach showed promising results regarding safety and efficacy.
Study context
- Population
- Patients with para-Hisian ventricular arrhythmias (VAs) with QRS morphological changes after catheter ablation (CA)of 30 undergoing CA
- Participants
- 10 patients
- Exposure
- Anatomical approach after QRS morphology change
- RLn = 7
- LRn = 3
- Outcome

80%
Observational data: associations, not effects.
Further findings
Precordial transition zone after CA
- Tended to be earlier in RL and later in LR
VA suppression in RL
- Successful VA suppression despite suboptimal left-side pace map concordance or relatively delayed earliest activation time
Safety
Ablation discontinued because of risk of AV block
- Ablation discontinued (AV block risk)
- 1 (10%)
