Outcomes of a Simplified Two‐Catheter Approach for Catheter Ablation of SVT in Pediatric Patients

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Catheter ablations are an established treatment for supraventricular tachycardia (SVT) in pediatric patients with high success and low complication rates typically. This study evaluated the procedural outcomes, safety, and recurrence rates of pediatric patients undergoing SVT ablation using a two‐catheter approach.

Safety of Intra‐Amniotic and Intra‐Fetal Digoxin Administration in Late Second‐Trimester Abortion by Dilation and Evacuation

Perspectives on Sexual and Reproductive Health, EarlyView.
ABSTRACT Objective The study's purpose was to determine the safety of two routes and doses of digoxin through assessment of systemic absorption, cardiac rhythm, and coagulation parameters injected as part of second‐trimester dilation and evacuation abortion.

A Statistical Model for Risk Stratification on the Basis of Left Ventricular Ejection Fraction and Heart-Rate Turbulence [PDF]

, 2000
The MPIP data set was used to obtain a model for mortality risk stratification of acute myocardial infarction patients. The predictors heart rate turbulence (HRT) and left-ventricular ejection fraction (LVEF) were employed. HRT was a categorical variable

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

Identification and catheter ablation of a zone of slow conduction in the reentrant circuit of ventricular tachycardia in humans [PDF]

, 1988
Three patients who had incessant ventricular tachycardia and in whom a zone of slow conduction was identified are presented. Each patient's tachycardia was refractory to multiple antiarrhythmic drugs and was being treated with amlodarone at the time of ...

Characteristics and identification of sites of chagasic ventricular tachycardia by endocardial mapping

Arquivos Brasileiros de Cardiologia, 1999
OBJECTIVE: To study electrophysiological characteristics that enable the identification and ablation of sites of chagasic tachycardia. METHODS: Thirty-one patients with chronic Chagas' heart disease and sustained ventricular tachycardia (SVT) underwent ...

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Neurocardiac crosstalk in inherited cardiac arrhythmias and cardiomyopathy

The Journal of Physiology, EarlyView.
Abstract figure legend In inherited cardiac arrhythmias and cardiomyopathy, arrhythmias are typically triggered by autonomic nervous system activity. Genetic mutations linked to these conditions cause pro‐arrhythmic alterations in both cardiomyocytes and neurons, with their pathophysiological crosstalk likely amplifying the manifestation of the disease.
