ECG 23 This ECG and chest X-ray are from a 70-year-old man who had had angina for some time and was being treated with a beta-blocker. He came to the A & E department complaining of pain similar to his angina, but much more severe and persistent for 4 h. He had a heart murmur. What do the ECG and chest X-ray show and what treatment would be appropriate?
