对角支供应左室前外侧区域,其急性闭塞导致aVL、I和/或V2段 ST段抬高,下壁导联ST段压低。间隔支供应室间隔,其急性闭塞导致V1导联ST段抬高。若对角支未受累,则意味着I、aVL和V2无ST段抬高。由于包绕型LAD累及左室下壁,上述导联ST段呈对应性压低。V1导联的Q波和室性早搏的qR型提示室间隔梗死,V3导联的R波丢失...

Thi pattern, a right bundle branch block with ST segment elevations in precordial leads V1 through V2-V3 (without evidence of structural or ischemic changes), is thought to be secondary to mutations in sodium, potassium, and calcium channels, as well as genes involved in regulation of these ...
Acute occlusion of a conal branch may cause ST-segment elevation in the V1–V3 leads.1 圆锥分支的急性闭塞可能导致V1–V3导联ST段抬高。1 The ST-segment elevation from V1 to V3 and hyperacute T-waves in V2 and V...
FIGURE 3. Sequential electrocardiographic changes during episode (second) of pain in chest TOP panel, Tracings taken at time when monitoring lead showed minimal ST-segment elevation, Note striking ST-segment elevation in inferior leads (2,3 and aVF) and anterior leads(V2 to V6),with ST-segment...
In APE, ST-segment elevation (STE) in leads V1 to V3/V4, mimicking anteroseptal myocardial infarction, is not a rare phenomenon. Negative T waves (NTW) in the precordial leads mimicking the "Wellens' syndrome" is an important ECG manifestation of APE. The evolution of these ECG changes–...

Constant ST segment elevationNon-ischemic ST segment elevationCardiac multi-slice computed tomography angiographyA constant ST-elevation was more often described in precordial leads. We presented it in leads II, III, AVF in 16 consecutive patients seeking to establish a link between it and clinical,...
