Restricting excessive cardiac action potential and QT prolongation: a vital role for IKs in human ventricular muscle [PDF]

, 2005
Background - Although pharmacological block of the slow, delayed rectifier potassium current (I-Ks) by chromanol 293B, L-735,821, or HMR-1556 produces little effect on action potential duration (APD) in isolated rabbit and dog ventricular myocytes, the ...

Time-domain signal-averaged electrocardiogram in healthy German Shepherd and Boxer dogs

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
Signal-averaged electrocardiogram (SAECG) identifies ventricular late potentials (LP), low-amplitude electrical signals that are markers of slow cardiac conduction in fibrous myocardium, consisting in a predictive factor for sudden death in dogs at risk ...

Terminal S Wave Pattern in Lead V3 as a Simple Marker for Ventricular Tachycardia Risk Stratification in Patients With Repaired Tetralogy of Fallot

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Patients with repaired tetralogy of Fallot (rTOF) remain at risk of ventricular tachycardia (VT). This risk is most commonly related to slow conduction within the septal isthmus, which is defined as the region between the ventricular septal defect (VSD) patch and adjacent valvular annuli.

Demonstration of the presence of slow conduction during sustained ventricular tachycardia in man: use of transient entrainment of the tachycardia.

, 1987
To test the hypothesis that an area of slow conduction is present during reentrant ventricular tachycardia in man, and that the earliest activation site during ventricular tachycardia is within or orthodromically just distal to the area of slow ...

Gap Junctions, Slow Conduction, and Ventricular Tachycardia After Myocardial Infarction

Journal of the American College of Cardiology, 2012
Over the past 30 years, the cumulative results of clinical, experimental, and theoretical studies have validated the concept that slow conduction, related at least in part to changes in intercellular coupling via gap junctions, plays an important role in the pathogenesis of ventricular tachycardia (

Brugada Syndrome in the Pediatric Population: Diagnostic Challenges and Clinical Outcome—Results of the German Multicenter Study COGIA

Journal of Cardiovascular Electrophysiology, EarlyView.
The study examines 76 patients of the German multicenter study COGIA with suspected BrS in 12 centers in Germany. Thirty‐nine patients met the current ESC diagnostic criteria, 34 of whom met the Shanghai Score criteria. Four major arrhythmic events (ACA, SCD, appropriate ICD shock) occurred in the cohort (5.3%), all in the group of patients fulfilling ...

First United States Experience With Focal Pulsed‐Field Ablation Using the FARAPOINT Catheter for Refractory Ventricular Tachycardia

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Drug‐refractory ventricular tachycardia (VT) after failed radiofrequency (RF) ablation remains a clinical challenge. Pulsed‐field ablation (PFA) is expanding to ventricular applications, but United States experience with focal pulsed‐field‐only catheters in VT is sparse, and pulsed‐field platforms are not equivalent across ...
