Ventricular repolarization refers to the process by which the ventricles of the heart recover their electrical potential after contraction (depolarization). This phase of the cardiac cycle is critical for ensuring proper relaxation and preparation for the next heartbeat. Research in the area of ventricular repolarization focuses on understanding the mechanisms that regulate this process, including the role of ion channels, electrical gradients, and various signaling pathways. Abnormalities in ventricular repolarization can lead to arrhythmias and other heart conditions, making it an important area of study for improving our understanding of cardiovascular health and developing new therapeutic interventions.
