Significance of left posterior extension of early repolarization in patients with J-wave syndrome
Authors' conclusion
Posterior J waves are common in ERS patients.
Study context
- Population
- Patients diagnosed with early repolarization syndrome (ERS)
- Participants
- 40 patients
- Outcome
- Incidence of J waves in inferolateral and posterior leads (15-lead electrocardiographic (ECG) with synthesized V7-V9 and 87-lead body surface mapping)
Main finding
As reported in the abstract
J waves by lead region
J waves in lateral leads
26
65%
J waves in inferior leads
31
78%
J waves in posterior leads
39
97%
J waves only in posterior leads
5
Observational data: associations, not effects.
Further findings
Body surface mapping
- Patients evaluated with body surface mapping (BSM), all with positive area on posterior region
- 9
Premature ventricular complexes (PVCs) associated with ventricular fibrillation (VF)
- Patients with VF-associated PVCs recorded
- 5
- Among patients with inferolateral and posterior J waves, PVCs originated from posterior LV region in all except 1 (left bundle branch block morphology)
