讨论心电图显示窦性心律失常伴一度心脏传导阻滞，所有三个下壁导联（II、III和aVF）ST段抬高，右胸导联（V1和V2）ST段压低。下壁ST段抬高通常见于急性下壁透壁性梗死，可能继发于血栓或夹层导致的血管闭塞或右冠状动脉血管痉挛。右侧心前区ST段压低可代表与左室下壁缺血或左室后壁透壁梗死相关的相互变化。
DiscussionThe electrocardiogram shows sinus arrhythmia with first degree heart block, ST segment elevations in all three inferior leads (II, III, and aVF), and ST segment depressions in the right precordial leads (V1 and V2). Inferior ST segment elevations are generally observed with acute inferior wall transmural infarction, which can be secondary to vessel occlusion from thrombus or dissection, or from vasospasm of the right coronary artery. Right sided precordial ST segment depressions can represent reciprocal changes related to inferior left ventricular wall ischaemia or posterior left ventricular wall transmural infarction.
