Electrophysiology
Electrophysiology is a branch of physiology that deals with the electrical properties of biological cells and tissues. It focuses on the study of the electrical activity generated by living organisms, particularly in the nervous system and the heart.
In cardiology, electrophysiology refers to the study of the electrical activity of the heart, including the generation and propagation of cardiac action potentials. This can involve techniques such as electrocardiography (ECG) to measure the heart's electrical activity from the body surface, as well as invasive procedures like electrophysiological mapping and catheter ablation to diagnose and treat arrhythmias.
