I use a portable pocket ultrasound device instead of a stethoscope to listen to the heart, and I share it with the patient in real time. 'Look at your valve, look at your heart-muscle strength.' So they're looking at it with me. Normally a patient is tested by an ultrasonographer who is not allowed to tell them anything.

When you're asked to have a CT scan or a nuclear scan, do you know how much radiation that involves? How many of those sorts of scans have you already had? Is it necessary? Is there an alternative? I don't think many people know about that.

About half of all people don't take medications like they're supposed to.
