Jul 27th, 2020 - The slowly and rapidly activating delayed rectifier K+ channels (IKs and IKr, respectively) contribute to the repolarization of ventricular action potential in human heart and thereby determine QT interval on an electrocardiogram. Loss-of-function...

Jul 24th, 2020 - Female sex is a known risk factor for drug-induced long QT syndrome (diLQTS). We recently demonstrated a sex difference in apamin-sensitive small-conductance Ca2+-activated K+ current (IKAS) activation during β-adrenergic stimulation. The purpose ...

Jul 23rd, 2020 - Data on the optimal location of the ECG leads for the diagnosis of drug-induced long QT syndrome (diLQTS) with Torsades de Pointes (TdP) are lacking. We systematically reviewed the literature for ECGs of patients with diLQTS and subsequent TdP. We...

Jul 22nd, 2020 - Long QT syndrome (LQTS) is characterized by prolongation of the QT interval on the electrocardiogram (ECG). Clinically, LQTS is associated with the development of Torsades de Pointes (TdP), a well-defined polymorphic ventricular tachycardia and th...

Jul 22nd, 2020 - A significant shortening of the corrected QT interval (QTc) in addition to parasympathetic denervation after cardioneuroablation (CNA) was recently demonstrated in patients with vagally mediated bradyarrhythmias and normal QTc range. This study as...

Nov 18th, 2018 - Long QT syndrome (LQTS) is associated with potentially fatal arrhythmias. Treatment is very effective, but its diagnosis may be challenging. Importantly, different methods are used to assess the QT interval, which makes its recognition difficult. ...

May 13th, 2018 - Artificial intelligence can identify congenital Long QT Syndrome on a single lead ECG, even in patients with a normal electrocardiogram, said researchers from AliveCor -- whose KardiaBand add-on for the Apple Watch is such a device -- at the Heart...

Feb 16th, 2018 - A celebrated physician and and pioneer in sudden cardiac death research, Arthur Moss, MD, of University of Rochester Medical Center, passed away on Wednesday at age 86. His legacy is a career spanning more than 60 years that was marked by major co...

Oct 12th, 2016 - Action Points Data mining millions of electronic health records led to the discovery of a new drug interaction involving ceftriaxone and lansoprazole that is assocaited with acquired long QT syndrome. Note that the study suggests that a well-contr...

Nov 12th, 2013 - Action Points Checking fetal heart rhythms with magnetocardiography may be able to diagnose long QT syndrome and allow intervention before the baby is born. Note that for some of the fetuses, information gleaned from fetal magnetocardiography that...
