Acute Inferior Infarction: Anterior Reciprocal Changes

Report:

Sinus rhythm 82/min

First degree AV block

PR interval 0.28”

Acute inferior infarction

Comment:

The tracing is remarkable in that both lateral all the precordial leads show reciprocal ST segment depression, more than the previous example in Fig 8b. This implies a large infarction rather than additional ischæmia9.

Thrombolysis was only partially successful. Three days later, some of the acute changes are still present (Fig 11a), while the PR interval has normalised.
