The Ups and Downs of Your Heart Rhythms (Video)

Rhythm of your heart

Your heartbeat is triggered by electrical impulses that travel down a special pathway through your heart. At rest, most people’s hearts beat about 50 to 70 times each minute. That rate slows at what’s referred to as peaceful rest. When you exercise, your body needs more oxygen-rich blood, and your heart rate increases to compensate.

In this white board session, Patrick J. Tchou, MD, Associate Section Head of the Section of Electrophysiology and Cardiac Pacing in the Department of Cardiovascular Medicine, takes a behind-the-scenes look at how your heart makes all of this happen.

    I always ate butter. Makes sense, it’s real. Tastes better. I like salt. Red meat doesn’t always agree with me, same with too much dairy. Sad, I love ice cream. I didn’t always listen to the latest scientific findings. I use MY common sense. Which is not always reliable. So I investigate when I need to.

    In other words… eat Italian, not Itamerican.

    This fixation on cholesterol is quite antiquated, get with the program Cleveland!
    Cutting carbs sorts it all out, fat (incl saturated fat) is good. Do it radically and you lose lots of weight too, then ease off once you’ve reached your desired weight.
