Electrocardiogram – This is what we tend to do to most patients these days. It allows us to take a “snap shot” of the heart to see what is happening. Very useful for diagnosing heart conditions such as MI’s (heart attacks). It is done by placing several sticky lead placements across the patient’s chest and on limbs and obtaining a trace via our Lifepak machine. People with very hairy chests tend to get presented with the razor!
