Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Maternal respiratory sinus arrhythmia captures the severity of pre-eclampsia

, 2016
Pre-eclamsia is a gestational disease that leads to hemodynamic disorders, hypoperfusion of end organ and multiple organ failure. Respiratory sinus arrhythmia is known to be participated in regulation of heartrate, cardiac output, blood pressure and ...

Separating the effect of respiration from the heart rate variability for cases of constant harmonic breathing

Current Directions in Biomedical Engineering, 2015
Heart Rate Variability studies are a known measure for the autonomous control of the heart rate. In special situations, its interpretation can be ambiguous, since the respiration has a major influence on the heart rate variability. For this reason it has

FGF23 promotes atrial fibrillation susceptibility through ETV1‐dependent sodium channel regulation and calcium handling abnormalities

Experimental Physiology, EarlyView.
Abstract Fibroblast growth factor 23 (FGF23) is closely associated with atrial fibrillation (AF), yet whether it modulates sodium and calcium currents in atrial myocytes remains unclear. ETV1, a key transcription factor regulating atrial electrical conduction, might also be involved in FGF23‐mediated AF.

Respiratory Sinus Arrhythmia Acts as a Moderator of the Relationship Between Parental Marital Conflict and Adolescents’ Internalizing Problems

Frontiers in Neuroscience, 2019
The present study examined the potential moderating role respiratory sinus arrhythmia (RSA) plays in the relationship between parental marital conflict and adolescents’ internalizing problems.

Traumatic arteriovenous fistula after ice axe injury 27 years ago: A case report

Experimental Physiology, EarlyView.
Abstract We report a case of a traumatic arteriovenous fistula (AVF) between the superficial femoral artery and femoral vein that went undetected for 27 years following an ice axe injury during a climbing accident in 1997. An AVF is an abnormal connection between an artery and a vein, where blood flows directly from the high‐flow arterial system to the

Non‐invasive assessment of integrated cardiorespiratory network dynamics after physiological stress in humans

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to develop a non‐invasive method for visualizing the cardiorespiratory network under baseline conditions and following isolated or combined exposure to hypoxia, exercise, and sleep deprivation. Twenty‐two healthy participants underwent assessments at rest and after normobaric hypoxia (FIO2${{F}_{{\mathrm{I ...

The ultrarapid delayed rectifier potassium current has important functional role in the repolarization reserve of canine and human ventricular muscle

The Journal of Physiology, EarlyView.
Abstract figure legend The ultrarapid delayed rectifier potassium current (IKur) has long been considered an atrial‐specific current with no functional role in the ventricles, despite evidence of its expression in ventricular myocytes. In the present study we challenged this prevailing concept and investigated the potential role of IKur in ventricular ...

Sympathetic restraint of respiratory sinus arrhythmia: implications for vagal-cardiac tone assessment in humans

, 2001
Clinicians and experimentalists routinely estimate vagal-cardiac nerve traffic from respiratory sinus arrhythmia. However, evidence suggests that sympathetic mechanisms may also modulate respiratory sinus arrhythmia.
