Preliminary investigation on corresponding relationship between isolated Q wave of standard limb-lead Ⅲ and sonographic infarct site / 中华超声影像学杂志

ABSTRACT

Objective To explore the corresponding relationship between isolated Q waves in lead Ⅲ on the electrocardiography(ECG) and echocardiographie segmental diagnosis of myocardial infarction(MI).Methods The shape magnitude of Q waves of 27 patients with MI and the relationship with eehocardiographie features were investigated. Results Twenty-four patients with inferior wall myocardial infarction had close relationship with isolated Q waves in lead Ⅲ on the ECG. Conclusions There is definite corresponding relation between isolated Q waves in lead Ⅲ and inferior wall myocardial infarction.
