Driving restrictions in patients with implantable cardioverter defibrillators and pacemakers
Publication date: Available online 28 March 2017 Source:Journal of Arrhythmia Author(s): Eiichi Watanabe, Haruhiko Abe, Shigeyuki Watanabe Implantable cardioverter-defibrillators (ICDs) improve the survival in patients at risk of sudden cardiac death. However, these patients have an ongoing risk of sudden incapacitation that may cause harm to individuals and others when driving. Considerable disagreement exists about whether and when these patients should be allowed to resume driving after ICD therapies. This information is critical for the management decisions to avoid future potentially lethal incidents and unnecess...

Importance of exercise testing shortly after subcutaneous implantable cardioverter-defibrillator implantation in patients with Brugada syndrome – The first case of associated inappropriate shock in Japan
We report the case of a 51-year-old patient with Brugada syndrome (BrS) who experienced inappropriate shock due to T-wave oversensing (TWOS) during exercise when the optimal sensing vector was selected based on the automatic analysis by a subcutaneous implantable cardioverter-defibrillator (S-ICD). After selecting another vector during exercise testing, TWOS did not re-occur. Selection of appropriate sensing vector based on analyses under various conditions, including during exercise after S-ICD implantation, should be considered for patients with BrS.

Airway support using a pediatric intubation tube in adult patients with atrial fibrillation: A simple and unique method to prevent heart movement during catheter ablation under continuous deep sedation
Conclusion This unique airway management technique using a pediatric intubation tube for CA procedures performed in adult patients with AF under continuous deep sedation was easy, safe, and effective. (Source: Journal of Arrhythmia)

Asystole in focal epilepsy complicating a traumatic subdural hematoma
Publication date: Available online 16 February 2017 Source:Journal of Arrhythmia Author(s): Yuk-Ming Lau, Chi-Hung Lo, Kathy Lai-Fun Lee, Chu-Pak Lau Ictal asystole due to sinus node suppression is a cause of sudden unexplained death in epilepsy. Here, for the first time, we describe a complete atrioventricular nodal block in a patient with non-compressive traumatic subdural hematoma, who developed ictal asystole as a delayed presentation. A leadless VVI pacemaker (ventricular paced, ventricular sensed, and pacing inhibited in response to a sensed beat) was implanted as a preventive measure against seizure-related he...

Wavefront direction and cycle length affect left atrial electrogram amplitude
Conclusion The rate and direction-dependent reduction of the amplitude of atrial EGMs may explain, in part, the voltage discordance during SR and AF. (Source: Journal of Arrhythmia)

Intracoronary acetylcholine application as a possible probe inducing J waves in patients with early repolarization syndrome
Publication date: Available online 6 February 2017 Source:Journal of Arrhythmia Author(s): Toru Maruyama, Kazumasa Fujita, Kei Irie, Shouhei Moriyama, Mitsuhiro Fukata Acetylcholine is widely used for a diagnostic provocation test of coronary spasm in patients with vasospastic angina. Acetylcholine usually induces coronary vasodilatation mediated by muscarinic receptor activation, but sometimes it evokes vasoconstriction of coronary arteries where the endothelium is damaged. Early repolarization syndrome is characterized by a J wave observed at the end of the QRS complex in a surface electrocardiogram. The J wave is...

High-resolution mapping and ablation of recurrent left lateral accessory pathway conduction
We report a case of recurring AP conduction that was finally eliminated using a novel ablation catheter equipped with high-resolution mini-electrodes. Smaller and closer electrodes result in high mapping resolution with less signal averaging and cancellation effects. Owing to improved sensitivity, the new catheter seems effective in detecting fragmented and high frequency signals, thus allowing more effective radiofrequency application and improving ablation success.

Focal ablation for atrial tachycardia from the double-exit of the Marshall bundle inducing atrial fibrillation
We report the case of a 23-year-old woman with an antiarrhythmic drug-resistant AF induced by two distinct atrial tachycardias (ATs). Focal ablation of these ATs from the double-exit of the Marshall bundle using a three-dimensional map eliminated AF triggering, even though pulmonary vein electrical isolation is the cornerstone for paroxysmal AF. Such mechanisms are important as triggering factors to plan ablation for paroxysmal AF. Focal ablation for triggering and inducing AF, originating from the double-exit of the Marshall bundle may be effective in eliminating AF in young patients. (Source: Journal of Arrhythmia)

Current use of direct oral anticoagulants for atrial fibrillation in Japan: Findings from the SAKURA AF Registry
Conclusions Our initial analysis of the SAKURA AF Registry data clarified the real-world use of anticoagulants, which includes DOACs and warfarin in Japan. The DOAC users were at a lower risk for stroke than the warfarin users. In 20–30% of DOAC users, the dose was inappropriately reduced. (Source: Journal of Arrhythmia)
