ELECTROCARDIOGRAM EKG (EEG) Remember: The heart has its own electrical system. Do you remember the three parts? Name them:

SA - Sinoatrial Node AV - Atrioventricular Node 3. Purkinje Fibers

Current passes through body to skin. Current can be measured with an electrocardiogram. (EKG,ECG) Vernier.com

What Does an EKG Look Like? P = P Wave- Just before atrial contraction QRS Complex- Impulse causing ventricle contraction T= T Wave – Ventricles relax R P Through T = Systolic Pressure T Through P = Diastolic T p Q S Direction of impulse
