Diffuse ST depression with ST elevation in aVR: Is this pattern specific for global ischemia due to left main coronary artery disease? Opinions vary widely on the K level at which a patient must be admitted on a monitor because of the risk of ventricular dysrhythmias. J Electrocardiol 2013;46:240-8. K less than 2.8.

Inferior MI results in scar tissue which is a likely source of a re-entrant ventricular dysrhythmia. Angiogram: Severe coronary artery calcification Moderate to severe distal small vessel disease mainly seen in RPL1, 2 Otherwise, Mild plaque, no angiographically significant obstructive coronary artery disease.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. The patient was brought directly to the cardiac catheterization lab for PCI, bypassing the ED. In the cath lab, the patient’s blood pressure remained low.
