Before you begin...

This quiz consists of 15 MCQs and should take approximately 45 minutes to complete. The ECGs are kindly provided by Dr Smith's ECG blog.

All of the patients in this quiz have chest pain. You will need to identify whether their ECG demonstrates ST-segment changes consistent with acute coronary artery occlusion, and, if so, which myocardial territory is likely to be ischaemic.

The often-missed "posterior" infarction may feature in this quiz. If you are unfamiliar with this concept, click the 'Posterior OMI' tab on our ECG guide.

From Dr. Smith, Dr. Meyers, Dr. McLaren, Dr. Yates, and student Dr. Kahle -- good luck!
