Your Heart is a Human Electrical System (Video)

Electrical System of the Heart

The heart is a big muscle, and like all muscles, it conducts electrical impulses that keep your blood circulating through your body. The entire circulatory system isn’t unlike the electrical system in a house—which most people don’t think about unless the system fails. But when it’s running well, your heart’s electrical system is an amazing thing.

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, explains how your heart serves as a special power source to keep your blood pumping, beat by beat.

    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.
