Inferolateral myocardial infarction and ventricular ectopics

Inferolateral myocardial infarction and ventricular ectopics: Inferior wall infarction is manifested as Q, ST elevation and T wave inversion in inferior leads (II, III and aVF). Lateral wall involvement is seen as ST segment depression in I and aVL plus ST segment depression and T wave inversion in V5 and V6. Ventricular ectopics are the intermittent bizarre, wide QRS complexes not preceded by a P wave and with discordant ST segment and T waves (opposite in polarity to the dominant QRS). Even this is a 12 lead ECG none of the leads seem to have been acquired simultaneously. Please note that the ventricular ectopic beats are not in the same position in the different leads. The ventricular ectopics are monomorphic (same morphology in a given lead) and possibly unifocal.
