Discussion Tachycardia is a rapid heart rate that is above normal for age and level of exertion. Tachycardia is common, particularly sinus tachycardia due to normally encountered circumstances such as pain, fever or exercise. It is usually a normal physiologic process but sustained tachycardia often indicates a potentially abnormal underlying cause. Sinus tachycardia has a rapid heart rate with normal P waves and P-R intervals and variations from moment to moment and respiration. Generally it is not over 200 beats/minute. Vagal stimulation can slow the heart rate; this is a gradual slowing, not an abrupt slowing seen in ...

ConclusionThe data from our patient collective indicate that CPVT3 occurs much more frequently than previously expected. Variants inTECRL may be causative in up to 5 % of all CPVT cases. According to these findings, default analysis of this gene is recommended if CPVT is suspected.This article is protected by copyright. All rights reserved.
AbstractBackgroundThe prognostic implications of non-sustained ventricular tachycardia (NSVT) and their significance as therapeutic targets in patients without prior sustained ventricular arrhythmias remain undetermined. The aim of this study was to investigate the prognostic significance of asymptomatic NSVT in patients who had primary prevention implantable cardioverter-defibrillator (ICD) implantation due to ischemic or non-ischemic cardiomyopathy (ICM, NICM).MethodsWe enrolled 157 consecutive primary prevention ICD patients without previous appropriate ICD therapy (AIT). Patients were allocated to two groups depending ...
Stereotaxis, with offices in St. Louis, MO and the Netherlands, has won FDA clearance for the Genesis RMN System, a new generation of the company’s robotic navigation systems for the delivery of magnetic ablation catheters to address cardiac ar...
ConclusionICD therapy is effective for primary and secondary prevention of SCD in BrS. Whilst appropriate shocks occur more frequently in BrS patients presenting with VT/VF, they also occur in asymptomatic patients. Further research in risk stratification can improve patient prognosis while avoid unnecessary ICD implantation.
Recently, stereotactic radiosurgery has been applied to arrhythmias (stereotactic arrhythmia radioablation – STAR), with promising results reported in patients with refractory, scar-related VT, a cohort with known high morbidity and mortality.
Conclusions: Our data suggest that integrin β1D deficiency represents a novel mechanism underlying the increased risk of ventricular arrhythmias in patients with ARVC. PMID: 32122157 [PubMed - as supplied by publisher]

Conclusion: Radiofrequency ablation helps treat PVCs and PVT in children and has a higher efficacy in restoring and maintaining sinus rhythm.
