Evaluation of periesophageal nerve injury after pulmonary vein isolation using the 13C-acetate breath test
Conclusions Asymptomatic gastric hypomotility occurred more often after PVI. However, the average impact of PVI on gastric motility was minimal. (Source: Journal of Arrhythmia)

Identifying the true origin of sustained monomorphic ventricular tachycardia associated with dilated-phase hypertrophic cardiomyopathy: A case of successful catheter ablation
Publication date: Available online 14 July 2015 Source:Journal of Arrhythmia Author(s): Hiroshi Kawakami , Takayuki Nagai , Akira Fujii , Teruyoshi Uetani , Kazuhisa Nishimura , Katsuji Inoue , Jun Suzuki , Kazuhiro Satomi , Takafumi Okura , Jitsuo Higaki , Akiyoshi Ogimoto This case report describes sustained monomorphic ventricular tachycardia (VT) caused by a large epicardial scar, related to dilated-phase hypertrophic cardiomyopathy mimicking VT originating from the apical septum. VT resolved with epicardial catheter ablation. The exit of the VT circuit suggested that a 12-lead electrocardiogram can be r...

Efficacy of ablation at the anteroseptal line for the treatment of perimitral flutter
Conclusion Ablation at the left atrial anteroseptal line is safe and efficacious for the treatment of PMF. Unlike ablation at the traditional mitral isthmus line, ablation at the left atrial anteroseptal line does not require ablation in the coronary sinus. (Source: Journal of Arrhythmia)

Effects of a high-fat diet on the electrical properties of porcine atria
Conclusions The shorter ERPs for the PV observed in response to the HFD increased vulnerability to AF, and these electrophysiological characteristics may underlie obesity-related AF. (Source: Journal of Arrhythmia)

Aortic perforation due to cardiac resynchronisation therapy defibrillator lead placement: Case report and medicolegal considerations
Publication date: Available online 16 June 2015 Source:Journal of Arrhythmia Author(s): Antonino M. Grande , Antonio Fiore , Maurizio Merlano , Fabio Buzzi , Alessandro Mazzola A 45-year-old woman with dilated cardiomyopathy was admitted for the upgrade of a previously implanted pacemaker. Echocardiography showed intraventricular dyssynchrony and a low ejection fraction (0.35). Treatment with a cardiac resynchronization therapy defibrillator (CRT-D) was selected and the device was implanted. CRT-D interrogation revealed proper function. Following procedure termination, the patient went into cardiac arrest and died...

Ability of magnetocardiography to detect regional dominant frequencies of atrial fibrillation
Conclusions MCG could more precisely detect the DFs in the LA and the CS than ECG. However, the usefulness of pre-procedural detection of the AF frequency gradient for ablation therapy needs to be evaluated in future prospective studies. (Source: Journal of Arrhythmia)

A case of inappropriate implantable cardioverter defibrillator therapy induced by T-wave oversensing due to hyperkalemia
We present the case of a 70-year-old man who received inappropriate ICD shocks due to hyperkalemia-induced T-wave oversensing. The T-wave amplitudes on both the ICD electrogram and 12-lead ECG corresponded and normalized after normalization of the potassium level. (Source: Journal of Arrhythmia)

The impact of yoga on atrial fibrillation: A review of The Yoga My Heart Study
Publication date: Available online 6 June 2015 Source:Journal of Arrhythmia Author(s): Steven Brent Deutsch , Eric Lawrence Krivitsky Atrial fibrillation is a common arrhythmia affecting thousands of individuals worldwide. It is a conduction disorder that causes the heart to beat irregularly and rapidly. There are a few medical approaches to manage this costly health care burden: antiarrhythmics to maintain normal sinus rhythm, beta blockers to achieve rate control while allowing atrial fibrillation to persist, and electro-physiologic intervention for rate and rhythm control. These treatments can be costly and are no...

A case of dual atrioventricular nodal nonreentrant tachycardia: An unusual cause of tachycardia-induced cardiomyopathy
We report on a 45-year-old female who developed cardiomyopathy due to incessant dual atrioventricular nodal nonreentrant tachycardia. Her condition was completely resolved by performing radiofrequency ablation of the slow pathway. (Source: Journal of Arrhythmia)

Recurrent syncope in two patients with a sigmoid-shaped interventricular septum and no left ventricular hypertrophy

However, several patients have been reported to have clinical symptoms due to the narrowing of the left ventricular outflow tract (LVOT). Two patients with SIS presented with recurrent episodes of syncope after drinking or taking sublingual nitroglycerin...

Clinical presentation and course of long QT syndrome in Thai children
Conclusions All 20 patients with LQTS were mostly symptomatic at presentation. Owing to the geographical region and ethnicity of the Thai population, we conclude that the ratio of patients who develop cardiac symptoms at rest or during sleep might be higher than in other Asian countries.

A case of extensive encircling pulmonary vein isolation in a patient with severe scoliosis

Scoliosis may impair cardiorespiratory function. Enhanced computed tomography (CT) was helpful for the Brockenbrough method. Three-dimensional (3D) mapping also demonstrated clockwise rotation of the heart. We successfully isolated extensive encircling pulmonary vein in this pa...
