Objective:To study the mechanism and clinical significance of the precordial ST segment deviations in acute inferiorwall myocardial infarction (AIMI) involving adjacent area. Methods: Characteristics of electrocardiogram were analyzed in118 patients with AIMI. Results: (1)The magnitude of ST segment elevation of inferior wall leads (Ⅱ, Ⅲ and aVF) wassignificantly negatively correlated with that of precordial leads (P＜0.01). (2)The changed magnitude of ST segment oflead V2 (0.63±1.82 mm) and V2/aVF ratio (0.84±1.61) in 16 cases associated with right ventricular infarction weresignificantly higher than those of only inferior wall myocardial infarction group (V2:0.35±1.65 mm,V2/aVF ratio:0.29±1.28)(P＞0.05 and P＞0.05). (3)The magnitude of ST segment fall of lead V2(-1.20±1.52 mm) and V2/aVFratio (-0.33±1.15) in 38 cases associated with lateral-posterior wall in farction were higher than those of only inferiorwall infarction group (P＜0.05). (4)If the cases associated with right ventricular and lateral-posterior wall infarction werenot included, the ST segment correlation coefficient between inferior and precordial leads would significantly increase inAIMI (r =-0.797, P＜0.01). Conclusion:The directions of ST segment deviations of precordial leads elevate in casesassociated with right ventricular infarction and fall in eases associated with lateral-posterior wall infarction in AIMI.
