Today we're talking the heart and heart throbs -- both literal and those of the televised variety. Hank explains how your heart’s pacemaker cells use leaky membranes to generate their own action potentials, and how the resulting electricity travels through the cardiac conduction pathway from SA Node to Purkinje fibers, allowing your heart to contract. He's also going to make you better able to spot inaccuracies in medical dramas by explaining how defibrillators work to reset the rhythm of your heart.
