The standard 12-lead electrocardiogram is a representation that provides comprehensive and spatial information of the heart's electrical activity. It needs to be correctly and accurately interpreted, related to the patient clinical history.
ECG interpretation involves evaluating several key aspects of the cardiac electrical activity. These include:
1. Determining the rhythm
2. Calculating heart rate
3. Calculating the PR Segment
4. Calculating the QT Interval
5. Cardiac axis determination in the frontal plane
6. Analyzing morphologies of the P Wave, the QRS Complex, the ST Segment, the T Wave and the U Wave
