Abstract Aims Action potential duration (APD) alternans is an established precursor or arrhythmia and sudden cardiac death… Expand Repolarization alternans (RA), originating at the cellular level, is thought to produce an arrhythmogenic substrate, and surface… Expand Electrocardiographic alternans, a phenomenon of beat-to-beat oscillation in electrocardiographic (ECG) waveforms, was first… Expand OBJECTIVE
To investigate the effect and potential mechanism of lysophosphatidic acid (LPA) and antiarrhythmic peptide (AAP10) on… Expand Ito and Myocyte Contractility. Introduction: The transient outward current (Ito) is a major repolarizing current in the heart… Expand Several studies suggest link between repolarization alternans and arrhythmia.
