Voila! EKG
Electrical Impulse of the Heart
• Muscle cells of the heart are negatively charged (polarized) in their resting state.
• When heart muscle is electrically stimulated the cells become positively charged (depolarized) and this causes them to contract.
Electrical Impulse of the Heart
• We are interested in how the electrical impulse is conducted through cardiac tissue.
