electroanatomical

Electroanatomical refers to the representation or mapping of electrical activity within an anatomical structure. This concept is most commonly encountered in the field of electrophysiology, particularly in cardiology. Electroanatomical mapping systems are used to create detailed, real-time three-dimensional images of the heart's electrical pathways. These systems typically utilize specialized catheters with electrodes that are advanced into the heart chambers. As the electrodes record electrical signals, sophisticated computer software translates this data into a color-coded map. The colors often represent the timing of electrical activation, with different hues indicating different phases of the cardiac cycle. This allows physicians to visualize areas of abnormal electrical conduction, such as those responsible for arrhythmias like atrial fibrillation or ventricular tachycardia. By precisely identifying the source and spread of electrical impulses, electroanatomical mapping aids in diagnosis and guides therapeutic interventions, such as catheter ablation. The technology has significantly advanced the understanding and treatment of complex cardiac electrical disorders. Beyond cardiology, the term can also be applied more broadly to any technique that correlates electrical phenomena with biological anatomy.
