A proposal of clinical ECG index “vagal score” for determining the mechanism of paroxysmal atrioventricular block
Conclusions The VS is simple and potentially useful for determining the mechanism of P-AVB. P-AVB with a VS ≥3 strongly suggested a vagally mediated mechanism. (Source: Journal of Arrhythmia)

Two cases of inappropriate implantable cardioverter-defibrillator therapies due to T wave oversensing induced by body twisting
We report two cases of inappropriate ICD therapy due to TWOS, which were induced only by body twisting. We can successfully manage the device based on the evidence of reproduced TWOS. (Source: Journal of Arrhythmia)

Complex fractionated atrial electrograms, high dominant frequency regions, and left atrial voltages during sinus rhythm and atrial fibrillation
Conclusions CFAEs and high DF areas during AF do not reflect damaged atrial myocardium as shown by the SR voltage. However, CFAEs and high DF sites may demonstrate different electrophysiologic properties because of different voltage amplitude during AF. (Source: Journal of Arrhythmia)

Molecular mechanisms underlying the pilsicainide-induced stabilization of hERG proteins in transfected mammalian cells
Conclusions Pilsicainide penetrates the plasma membrane, stabilizes WT-hERG proteins by acting as a chemical chaperone, and enhances WT-hERG channel currents. This mechanism could also be applicable to modulations of certain mutant-hERG proteins. (Source: Journal of Arrhythmia)

Anatomical dilatation of the superior vena cava associated with an arrhythmogenic response induced by SVC scan pacing after atrial fibrillation ablation
Conclusion Dilatation of SVC was associated with an arrhythmogenic response, and the AF recurrence rate was significantly higher in patients with large SVC-area. Adjunctive catheter intervention for the SVC might be indicated in patients with a dilated SVC and an arrhythmogenic response. (Source: Journal of Arrhythmia)

Report of periprocedural oral anticoagulants in catheter ablation for atrial fibrillation: The Japanese Catheter Ablation Registry of Atrial Fibrillation (J-CARAF)
Conclusions Compared with uninterrupted warfarin, the choice of a direct oral anticoagulant as a periprocedural oral anticoagulant did not significantly change the incidence of serious complications. (Source: Journal of Arrhythmia)

The utility of atrial pacing for identifying the electrical breakthrough sites between the left atrium and pulmonary veins
Conclusions This pacing method may help to identify whether EBSs are located in the anterior Lt.PVs. Improved recognition of EBSs through pacing from different sites would be helpful for achieving PV isolation. (Source: Journal of Arrhythmia)

Inappropriate shocks from a subcutaneous implantable cardioverter-defibrillator due to oversensing during periods of rate-related bundle branch block
We describe the case of a 55-year-old female patient implanted with an S-ICD due to idiopathic ventricular fibrillation, who subsequently presented with inappropriate shocks leading to ventricular fibrillation that was successfully terminated by another shock. Inappropriate shocks were due to intermittent T wave oversensing during periods of rate-dependent right bundle branch block. Assessment of the S-ICD electrograms during an exercise test allowed successful reprogramming of the device׳s sensing vector with no further events. (Source: Journal of Arrhythmia)

Atrial electromechanical delay in patients undergoing heart transplantation
Conclusion Inter-AEMD and intra-AEMD were prolonged in patients who underwent heart transplantation as compared to a control population. This may explain the increased atrial fibrillation and other atrial arrhythmia incidences associated with the biatrial anastomosis heart transplantation technique and may contribute to the treatment of atrial fibrillation in this special patient group.
