Acute Anteroseptal Infarction

Report:

Sinus rhythm 72/min

Acute anteroseptal infarction

Leads V1 and V3 transposed

Comment:

The biphasic P wave in the displaced V1 indicates that the lead is in correct position (on the patient). There are new Q waves in V1 and V2, with ST segment elevation reaching V5; this could be equally called anterior, rather than anteroseptal, infarction. But the report above is based on Q waves.

The inferior leads show the expected reciprocral ST depression.

The patient presented with ischæmic ECG (below, Fig 101a) several days earlier but the treatment, such as it was, failed to prevent progression to frank infarction.
