Oxidant stress can contribute to health and disease. Here we show that invertebrates and vertebrates share a common stereospecific redox pathway that protects against pathological responses to stress, at the cost of reduced physiological performance, by constraining Ca2+/calmodulin-dependent protein kinase II (CaMKII) activity. MICAL1, a methionine monooxygenase thought to exclusively target actin, and MSRB, a methionine reductase, control the stereospecific redox status of M308, a highly conserved residue in the calmodulin-binding (CaM-binding) domain of CaMKII. Oxidized or mutant M308 (M308V) decreased CaM binding and Ca...

ABSTRACTAimsNon ‐sustained ventricular tachycardia (NSVT) occurs frequently in patients with dilated cardiomyopathy (DCM), especially in high‐risk patients. The role of rapid‐rate NSVT (RR‐NSVT) documented by an implantable cardioverter defibrillator (ICD) in DCM patients has not been fully explored. This s tudy aimed to determine the relationship between RR‐NSVT and the occurrence of ventricular tachyarrhythmias (VTAs) in DCM patients with ICD.MethodsFrom December 2000 to December 2017, 136 DCM patients received ICD or cardiac resynchronization therapy defibrillator (CRT ‐D) implantation for primary or seconda...
Conclusions: In-hospital adverse cardiovascular events were significantly more frequent for patients with SCAD who presented with VA. However, follow-up events were not statistically significant between those with and without VA at presentation.
We describe clinical characteristics, workup, surgical techniques and outcomes of ARCA-IA at our center. A retrospective analysis of cardiovascular database was performed. From March 2005 through January 2011, 11 patients with mean age of 53 ± 18 years were diagnosed with ARCA-IA. Reported symptoms included chest pain (64%), arrhythmia [27%; i.e. atrial flutter (9%), recurrent supraventricular tachycardia (9%), ventricular tachycardia (9%)], syncope (18%), dyspnea (9%) and aborted sudden cardiac death (9%). Chest pain (n = 7) was episodic and lasted longer than 6 months befo...

The HRS/EHRA/APHRS/LAHRS expert consensus statement on optimal implantable cardioverter-defibrillator (ICD) programming recommends burst antitachycardia pacing (ATP) for treatment of ventricular tachycardia (VT) up to very high rates. The number of bursts is not specified and treatment by ramps or low-energy shocks are not recommended.

ConclusionSimultaneous ablation with high output pacing to achieve scar inexacitability, when combined with scar homogenisation and non inducibility of any VT may be an expeditious, safe and effective technique for catheter ablation.This article is protected by copyright. All rights reserved
