Persistent inappropriate sinus tachycardia after radiofrequency current catheter modification of the atrioventricular node

, 1992
Atrioventricular (AV) junctional reentrant tachycardia (JRT) is the most frequent cause of paroxysmal supraventricular tachycardia. 1 Recently, radiofrequency current delivered through a transvenous catheter was used to modify AV nodal properties so that

Stabilizing Extreme Few‐Shot ECG Classification via Self‐Supervised Contrastive Pretraining

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
Under extreme few‐shot ECG classification, supervised training frequently collapses to degenerate solutions. Self‐supervised pretraining stabilizes optimization, eliminates early collapse, and enables reproducible multi‐class rhythm classification with limited labeled data. ABSTRACT In clinical electrocardiogram (ECG) analysis, high‐quality annotations
