Interplay of Probe Stability and Oscillation During Very‐High‐Power Short‐Duration Ablation in Pulmonary Vein Isolation for Atrial Fibrillation

Pacing and Clinical Electrophysiology, EarlyView.
This graphical abstract presents a comprehensive analysis of probe stability and oscillation during very high‐power short‐duration (vHPSD) pulmonary vein isolation (PVI) for atrial fibrillation. The findings indicate that oscillation velocity serves as a more reliable predictor of impedance drop and temperature changes than contact force alone ...

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.

RESPIRATORY SINUS ARRHYTHMIA: AN INDEX OF LIGHT ANAESTHESIA

British Journal of Anaesthesia, 1993
This study was designed to test if changes in the degree of respiratory sinus arrhythmia (RSA) can be used as an index of light anaesthesia. An on-line, real-time data logging system was used to record simultaneously the EEG and ECG waveforms from 10 patients undergoing routine surgery using i.v. propofol (Diprivan) anaesthesia.

PFA Under Deep Sedation and Non‐Invasive Monitoring in Atrial Fibrillation Patients With Obstructive Sleep Apnea

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Clinical data about pulsed field ablation (PFA) under deep sedation among patients with obstructive sleep apnea (OSA) are limited, while the optimal periprocedural monitoring is not established. We report our experience in PFA among patients with atrial fibrillation (AF) and OSA, using a continuous non‐invasive respiratory and ...

Absence of respiratory sinus arrhythmia: A manifestation of the sick sinus syndrome

Clinical Cardiology, 1983
AbstractThe failure of changes in autonomic drive to affect heart rate is a common finding in patients with the sick sinus syndrome (SSS). The normal respiratory sinus arrhythmia is vagally mediated and should therefore be attenuated in SSS. This hypothesis was tested in a series of 32 symptomatic patients with SSS, mean age 68 years, and an age ...

Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Fifty years ago, Werner Irnich presented the concept of an optimal pacemaker capable of responding appropriately to various cardiac arrhythmias and perceptual disturbances, and intended to be used in 85% of patients. With this concept, Irnich was far ahead of his time. His proposed circuitry for AV block and atrial fibrillation, as well as his

Effects of the angle of head‐down tilt on dynamic cerebral autoregulation during combined exposure to cephalad fluid shift and mild hypercapnia

Experimental Physiology, EarlyView.
Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

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.
