Ten-year experience in atenolol use and exercise evaluation in children with genetically proven long QT syndrome
Conclusions Atenolol is an effective treatment for genetically proven LQT1 and LQT2 children and adolescents, with good tolerability. In LQT1 patients, QTc intervals at 2–3min into the recovery phase of exercise were significantly prolonged, particularly in patients with transmembrane mutations. (Source: Journal of Arrhythmia)

Influence of proton pump inhibitors on blood dabigatran concentrations in Japanese patients with non-valvular atrial fibrillation
Conclusions PPI administration significantly decreased the trough and peak DCs in patients with NVAF. Therefore, when prescribing PPIs for patients with NVAF in a clinical setting, the possibility that the bioavailability of dabigatran may decrease should be considered.

Marshall bundle reentrant atrial tachycardia after the Cox-Maze IV procedure: The last barrier of the conduction pathway between the coronary sinus and left atrium
Publication date: Available online 12 October 2017 Source:Journal of Arrhythmia Author(s): Yasushi Wakabayashi, Takekuni Hayashi, Yoshitaka Sugawara, Takeshi Mitsuhashi, Hideo Fujita, Shin-ichi Momomura A 74-year-old woman who developed atrial tachycardia following the Cox-Maze IV procedure underwent catheter ablation. The reentrant circuit included the coronary sinus (CS), Marshall bundle (MB), distal MB-left atrial (LA) connection, and anterolateral mitral annulus. The distal MB-LA connection was the last barrier in the conduction pathway between the CS and the left atrium. (Source: Journal of Arrhythmia)

Extracardiac compression of the inferolateral branch of the coronary vein by the descending aorta in a patient with dilated cardiomyopathy
We present the case of a 69-year-old woman with dilated cardiomyopathy who underwent cardiac resynchronization therapy. Preoperative electrocardiography-gated contrast-enhanced computed tomography revealed the inferolateral wall of her significantly dilated and leftward-rotated heart was close to the descending aorta, and the descending aorta compressed the sandwiched inferolateral branch of the coronary vein. Retrograde coronary venography performed at the time of device implantation confirmed focal stenosis of the inferolateral branch of the coronary vein. (Source: Journal of Arrhythmia)

Ventricular arrhythmias in patients with Takotsubo syndrome
This article summarizes the prevalence, underlying mechanisms, therapeutic strategies, and prognostic implications of ventricular arrhythmias in TTS. Furthermore, the need for implantable cardioverter-defibrillators is discussed in view of the transient character of the disease. (Source: Journal of Arrhythmia)

Te, Shinya Yamada, Shih-Ann Chen Non-ischemic cardiomyopathies (NICMs) are composed of variable disease entities, including primary and secondary cardiomyopathies. Determining the etiology of NICM provides pivotal roles of not only the understanding of the individual pathogenesis, but also the clinical management, such as risk s...

The details of an unusual “ghost” after transvenous lead extraction: Three-dimensional computed tomography analysis
Publication date: Available online 6 September 2017 Source:Journal of Arrhythmia Author(s): Kunihiko Kiuchi, Koji Fukuzawa, Shumpei Mori, Tatsuya Nishii, Kensuke Matsumoto, Hirotoshi Ichibori, Takashi Yamada Transvenous lead extraction (TLE) is performed to prevent deaths in patients with device infections. Intracardiac masses detected by echocardiography, i.e., “ghosts,” are reported in 8% of patients after a TLE in retrospective studies and in 14% in prospective studies. We herein describe a case with unusual ghosts after a TLE. Three-dimensional computed tomography (3DCT) is useful for revealing all the det...

Role of head-up tilt table testing in patients with syncope or transient loss of consciousness
Publication date: Available online 6 September 2017 Source:Journal of Arrhythmia Author(s): Toshiyuki Furukawa The tilt table test (TTT) is a useful method for the management of reflex syncope. However, the TTT is incomplete and has several problems. The indications for this test are established using guidelines. The TTT is not suitable for all syncopal patients. It is currently unclear (1) When should the TTT be used, (2) for which types of patients TTT should be performed, and (3) does the TTT provide useful information to guide indication for pacing therapy for reflex syncope. The answers to these questions appear in...

Cardiac resynchronization therapy via transvenous approach in a 2-year-old boy with a complete atrioventricular block after a tetralogy of Fallot repair
Publication date: Available online 9 September 2017 Source:Journal of Arrhythmia Author(s): Hisaaki Aoki, Misugi Emi, Noboru Inamura, Shigemitsu Iwai, Futoshi Kayatani Cardiac resychronization therapy (CRT) was performed via transvenous approach in a 2-year-old boy with a tetralogy of Fallot and postoperative severe heart failure, and complete atrioventricular block treated with a dual-chamber pacemaker. Epicardial leads were unavailable because of mediastinitis and the presence of severe bilateral pleural effusions requiring continuous drainage. There were no procedural complications. Biventricular pacing was signi...
