Match the following terms with their definitions in the context of Electrocardiography:

Electrocardiography = The process of recording the electrical activity of the heart using electrodes Sinus Node = The group of cells that initiates each electrical signal in the heart Right Atrium = The upper right chamber of the heart where the sinus node is located SA Node = The abbreviation for the sinus node

Match the following functions with the corresponding descriptions in relation to Electrocardiography:

Diagnose and treat heart disease = One of the health problems addressed by ECG Record electrical activity of the heart = The main function of Electrocardiography Detect tiny electrical changes on the skin = What the electrodes in ECG do Reveal trends or changes in heart function = Another health problem addressed by ECG

Match the following parts of the heart with their related functions in the context of Electrocardiography:

Right Atrium = Location of the SA Node Electrodes = Detect the tiny electrical changes on the skin SA Node = Sends an electrical signal to begin a new heartbeat Heart Muscle = Generates the electro-physiologic pattern during each heartbeat

Match the following terms with their corresponding descriptions in the context of Electrocardiography:
