ECG Course Unit 2 – Principles of Cardiac Monitoring
This course covers the fundamental knowledge necessary for cardiac rhythm interpretation. The precordial and limb leads identify anatomical areas of the heart that is viewed by the 12-leads of the electrocardiogram (ECG). The waveforms, intervals, and components of the ECG complex are identified, and their correspondence to cardiac function are discussed. Information related to the measurement of these components, with methods of calculating heart rate are provided.
