Duodromic atrioventricular reentry tachycardia: a case report of a rare adenosine insensitive supraventricular tachycardia.
Eur Heart J Case Rep
January 2025
Arrhythmology, Pacing and Electrophysiology Unit, Cardiology Service, Santa Marta Hospital, Central Lisbon Hospital University Centre, R. de Santa Marta 50, Lisboa 1169-024, Portugal.
Background: Accessory pathways (AP) are associated with an increased risk of atrioventricular reentry tachycardia (AVRT), presenting as a wide QRS tachycardia if the mechanism is antidromic. Rarely, AVRT may not respond to adenosine, suggesting a duodromic mechanism if the patient has multiple APs. Herein, we present a case of a male patient with multiple APs, wide QRS complex tachycardia, and resistance to adenosine.

Douala Gyneco-obstetric and Pediatric Hospital/University of Douala, Douala, Cameroon.
Article Synopsis
- The study explores the management and diagnosis of Wolf-Parkinson White Syndrome (WPW) and asymptomatic pre-excitation in Africa, highlighting a lack of data in the region.
- Conducted in 20 centers across 17 African countries, the research involved 541 participants and focused on symptomatology, treatment approaches, and the impact of local health dynamics on care.
- Results indicated that a vast majority were diagnosed with WPW, with significant regional differences in treatment options and effectiveness, showing that Northern and Southern Africa have more advanced practices compared to other areas.
Pulsed Field Ablation of Paroxysmal Supraventricular Tachycardia: A Prospective Multicenter Single-Arm Study in China.
Circ Arrhythm Electrophysiol
December 2024
Department of Cardiology (F.L., A.G., H.H., K.C., Q.Y., X.P., S.C., J.J., H.F., H.W., T.Y., X.H., Y.T., Q. Zhang, R.Z.), , West China Hospital of Sichuan University, Chengdu.
Background: Pulsed field ablation (PFA) has gained attention in cardiac electrophysiology, but data on its application to paroxysmal supraventricular tachycardia are limited. This study aimed to assess the feasibility and safety of PFA and its combination with radiofrequency ablation for treating paroxysmal supraventricular tachycardia.
Methods: A prospective, multicenter, single-arm study was conducted across 8 centers in China.
Different patterns of pre-excitation in a large Italian cohort of asymptomatic non-competitive athletes evaluated by telecardiology screening: Prevalence and ECG features.
Int J Cardiol Heart Vasc
December 2024
Telemedico Srl-Telecardiology Center, Genova, Italy.
Article Synopsis
- - Telecardiology effectively enables ECG screening for large groups, successfully evaluating non-competitive athletes (NCA) across Italy over a four-year study period.
- - In a sample of 216,424 NCA, 88 individuals (4.1 per 10,000) were identified with Wolff-Parkinson-White (WPW) syndrome, primarily in the 10-15 year age group, with no significant sex differences noted.
- - The study revealed that the most common accessory pathways for WPW syndrome were in the right antero-septal, mid-septal, and postero-septal areas, with 9% of those diagnosed exhibiting intermittent pre-excitation.
Distinguishing Wolff-Parkinson-White Syndrome From Fasciculoventricular Pathway Using QRS-T Angle Analysis.
Pacing Clin Electrophysiol
January 2025
Division of Pediatric Electrophysiology, Pediatric Medical Care Center, Osaka City General Hospital, Osaka, Japan.
Article Synopsis
- Wolff-Parkinson-White (WPW) syndrome and fasciculoventricular pathway (FVP) both show delta waves on an ECG, but distinguishing between them, especially WPW type B, can be complex due to similar features.
- A study analyzed 40 WPW patients and 54 FVP patients to assess the QRS-T angle, resulting in a significantly larger QRS-T angle in the WPW group (45.7°) compared to FVP (17.8°).
- The research suggests that the QRS-T angle could be a useful marker for differentiating WPW syndrome from FVP, with a cut-off value of 22°
