冠状静脉解剖、造影及CRT心电图、左室电极影像

am, with still frames in anteroposterior (A) and left anterior oblique 30° (B). PV posterior vein; MV middle cardiac?vein; GV great cardiac vein; AV, anterior cardiac vein. Alongside are three-dimensional reconstructed images of the coronary venous tree, facilitating?segmental visualization of the coronary venous anatomy. The coronary venous ring is divisible into three segments: posterior (C), lateral (B), and anterior?(A), in both views. (B) The mid-ventricular position of a lateral segmental branch (1), closely corresponding to the second-order lateral tributary from an?anterior segmental branch, extending over the mid-ventricular region (2).Р冠状静脉造影Р各种不同左室电极Р4195Р4196Р4194Р4193Р4193Р4194Р4195Р4196Р头端电极直径Р5.4 FrР5.4 FrР5.3 FrР4.6 FrР环状电极直径РN/AР5.5 FrРN/AР5.1 FrР各种不同左室电极的X-ray?-常用左室电极4193
