Background: Fetal tachycardias can cause adverse fetal outcomes including ventricular dysfunction, hydrops, and fetal demise. Postnatally, ECG is the gold standard, but, in fetal practice, echocardiography is used most frequently to diagnose and monitor fetal arrhythmias. Noninvasive extraction of the fetal ECG (fECG) may provide additional information about the electrophysiological mechanism and monitoring of intermittent arrhythmias.

Introduction: Etripamil is a fast-acting intranasally self-administered calcium-channel blocker developed for termination of paroxysmal supraventricular tachycardia (PSVT). Prior studies have demonstrated safety and efficacy of etripamil for PSVT termination following an initial medically supervised test dose during sinus rhythm. NODE-303 is an open-label, single-arm study that evaluated etripamil for multiple, at-home PSVT episodes, without test dose before first use.

Neural oscillations in beta (13-30 Hz) and gamma (>30 Hz) frequency bands index a variety of sensorimotor and cognitive processes. To compare two rehabilitation regimens for chronic stroke patients with a hemiparetic hand, we randomly assigned them to either music-supported therapy or physiotherapy for 10 weeks. Previously, we reported the music group's improved motor speed, mood, well-being, and rhythm perception.

Background: Transvenous lead extraction (TLE) is increasingly performed in older adults, but literature has reported divergent outcomes in very old populations.
Objective: To investigate the impact of patient age on TLE outcomes, with an emphasis on older patients.
Methods: Using the ExTRACT registry, the largest TLE registry to date, we analyzed 5,090 patients who underwent TLE between August 1996-2022 at the Cleveland Clinic, a high-volume center.

Background: Electronic nicotine delivery systems (ENDS) utilize "E-liquids" in order to generate "E-vapor", an inhalable aerosolized mixture containing nicotine and flavors. Flavored ENDS are very popular among teens who vape, however, the possible cardiac electrophysiological harm of inhalation exposure to flavored ENDS are not fully understood.
Objective: To test if inhalation exposure to flavoring carbonyls in e-liquids compromises mitochondrial integrity, increases oxidative stress, and leads to cardiac electrophysiological toxicity.
