Abstract：
:Isolated occlusion of the septal perforating branch of the left anterior descending coronary artery is extremely rare. As a result, little is known about its electrocardiographic manifestations compared with those of an anteroseptal myocardial infarction. We present the case of an isolated septal myocardial infarction with ST-segment elevation.

杂志文章abstract：:The myocardial electrical conduction is significantly influenced by the sympathetic and parasympathetic nervous systems. Hypervagotonia refers to increased vagal tone leading to sinus bradycardia, sinus pause, or any degree of atrioventricular (AV) block. There are many clinical, electrocardiographic, and electrophysi...
