Tachyarrhythmia, Atrial Flutter, Paroxysmal Supraventricular Tachycardia, Atrial Tachycardia, Atrial Fibrillation, Premature Ventricular Contraction
Conditions
Brief summary
This is an exploratory research aiming to accurately identify the site of origin of tachyarrhythmia using Magnetocardiography (MCG), which will have guiding significance for early diagnosis, the formulation of treatment plans and preoperative positioning for radiofrequency ablation.
