ECG of the Week - 17th March 2014 - Interpretation

This is one of the older ECG's in my collection. I don't have any clinical information but it's safe to say the patient complained of chest pain.

This patient underwent thrombolysis acutely as per local policy at the time. I don't have any further clinical information on the case unfortunately.


I just thought I briefly touch on contraindications for thrombolysis in STEMI as I'm currently reading for the FACEM exam and it comes up occasionally. 
The following list is taken from the Australian Resuscitation Council Guideline 14.3 'Acute Coronary Syndromes: Reperfusion Strategy'.
