Natural history of ventricular premature contractions in children with a structurally normal heart: does origin matter?

, 2008
Aims Premature ventricular contractions (PVCs) are thought to be innocent in children with normal hearts, especially if they disappear during exercise.

A Stepwise ECG Algorithm to Resolve Identical Precordial Transition in Idiopathic Outflow Tract Ventricular Arrhythmias

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Accurate pre‐procedural differentiation of right (RVOT) versus left ventricular outflow tract (LVOT) origin in idiopathic outflow tract ventricular arrhythmias may facilitate procedural planning and mapping strategy. However, existing 12‐lead ECG criteria show variable performance and often fail to provide clear discrimination when ...

Ventricular Synchrony in Targeted Right Ventricular Septal Pacing: A Prospective Paired Comparison to Apical Placement

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background/Objectives Right ventricular (RV) apical pacing, the standard pacing approach, often induces ventricular dyssynchrony, potentially impairing cardiac function. This study aims to investigate whether targeted RV septal pacing, guided by functional electrophysiological feedback during implantation, reduces ventricular dyssynchrony ...

Short coupled premature ventricular contraction initiating ventricular fibrillation in a patient with Brugada syndrome.

, 2004
Patients with Brugada syndrome typically have ST segment elevation in ECG leads V1–V3, infrequent ventricular premature contractions with variable coupling intervals, inducible ventricular arrhythmia during electrophysiologic studies, and ventricular ...

Premature Ventricular Contraction-induced Cardiomyopathy

, 2017
Premature ventricular contractions (PVCs) are very common and usually do not require treatment. However, in the clinical setting of troublesome symptoms, or when PVCs trigger polymorphic ventricular tachycardia or cause cardiomyopathy, proper treatment ...

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.

Effects of ceiling fan use on cardiovascular autonomic function during simulated indoor overheating in bed‐resting older adults

Experimental Physiology, EarlyView.
Abstract Older adults are at heightened susceptibility to heat‐related cardiovascular complications when exposed to indoor overheating. While ceiling fans are recommended as an accessible cooling intervention, their effects on cardiac autonomic regulation remain unclear.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.
