Quantification of Ventricular Repolarization Variation for Sudden Cardiac Death Risk Stratification in Atrial Fibrillation

Abstract: Objective: Atrial fibrillation (AF) rhythm gives rise to an irregular response in ventricular activity, preventing the use of standard ECG-derived risk markers based on ventricular ...

Ventricular repolarization dispersion during ischemia course measured by temporal and spatial electrocardiographic parameters

Abstract: In this work we studied the evolution of increased ventricular repolarization dispersion (VRD) in the ECG during ischemia induced by Percutaneous Transluminal Coronary Angioplasty (PTCA).

K+-Channel Blockade can Suppress Phase 3 EADs by Slowing the Repolarization in an Electromechanical Cell Computational Model

The slowing of repolarization induced by 4-AP can favor stopping the reopening of Na+ channels during phase 3 EADs. Conclusion: In both types of EAD, a shorter, Ca2+- desensitized sarcomere can reduce ...

What Is a Normal Sinus Rhythm?

Normal sinus rhythm means the heartbeats are regular and between 60 and 100 beats per minute. Sinus rhythm is controlled by the sinus node, which sends electrical impulses to the heart. Bradycardia is ...
