St segment depression in lateral leads
WebThe typical and common ST-segment elevations are often founded in leads V1, V2, III, aVR while ST-segment depressions are often founded in leads I and V4/V5–V6 [14,15,17,19]. We have proposed that ischemic ECG changes in APE are mainly attributed to hypotension, hypoxemia, right ventricular stretches, and outpouring of catecholamines [14,15]. WebThe ST segment depression in the lateral leads is consistent with the altered conduction pattern in the LBBB patient; no evidence of inappropriate ST segment or T wave …
