The isthmus characteristics of scar‐related macroreentrant atrial tachycardia in patients with and without cardiac surgery
Abstract
Identifying the critical isthmus (CI) in scar‐related macroreentrant atrial tachycardia (AT) is challenging, especially for patients with cardiac surgery. We aimed to investigate the electrophysiological characteristics of scar‐related macroreentrant ATs in patients with and without cardiac surgery.
