Suspected myocardial infarction and left bundle branch block: electrocardiographic indicators of acute ischaemia.

Abstract

Currently, thrombolytic treatment is under-utilised in patients with LBBB and AMI, and those who are thrombolysed endure lengthy delays before treatment. Patients with any of the predictive criteria should be thrombolysed immediately. When the diagnosis is in doubt, serial ECGs may demonstrate evolving ischaemic change.
