Article Synopsis
- A study investigated the prevalence and predictors of complete atrioventricular block (C-AVB) that can occur after internal electrical cardioversion (IEC) during atrial fibrillation (AF) ablation.
- Of 124 patients undergoing the procedure, 88% had their AF terminated, and transient C-AVB occurred in 13% of those where AF was terminated, with longer ventricular pauses observed in those with C-AVB.
- Key predictors for experiencing transient C-AVB included a larger left atrial diameter and preexisting intraventricular conduction abnormalities.
We described the differential ventricular overdrive pacing during long RP' supraventricular tachycardia and discussed about its response leading to the dianosis.

Article Synopsis
- The study explores unidirectional block during AI-guided pulmonary vein isolation in patients with atrial fibrillation, specifically focusing on the entrance and exit blocks in the pulmonary veins (PVs).
- A total of 441 PVs from 113 patients were analyzed, finding that while entrance block was successfully achieved, only 2% demonstrated unidirectional blocks, with some cases requiring additional treatment to establish bidirectional block.
- The findings suggest that using entrance block as the main endpoint for pulmonary vein isolation is adequate due to the low occurrence of unidirectional block in this context.
We describe atrial activation sequence changes during ventricular overdrive pacing in a patient with a concealed left-sided accessory pathway and discuss its potential mechanism.

Methods: The 12‑lead electrocardiogram (ECG) data recorded before implantation of a cardiac implantable electronic device were analyzed in patients with greater than second-degree atrioventricular block (AVB).
The present case described an unusual clinical manifestation of the sinoatrial node (or sinoatrial junction) injury during superior vena cava isolation.

After the publication of the Global Vascular Guidelines in 2019, the evaluation of GLASS and identification of TAP have been recommended. However, there are few reports regarding GLASS.
View Article and Find Full Text PDFWe herein describe the case of a spontaneously observed bidirectional block (both entrance and exit block) at the sino-atrial junction. This bidirectional block at the sino-atrial junction associated with the failure of conduction to the ventricle revealed the Wenckebach periodicity of the atrio-ventricular conduction.
