**ECG Analysis Instructions** 1. Identify and color the following in the ECG image below: - Three P waves (color blue) - Three QRS complexes (color green) - Three T waves (color a different blue) - Three PR segments (color red) - Three ST segments (color purple) - Two full TP segments (color pink) - Two RR intervals (color brown) *(The RR interval indicates the time for one heartbeat. The RR interval is measured from the peak of one QRS to the peak of the next QRS).* **Graph/Diagram Explanation** The ECG image displays a standard electrocardiogram reading plotted on graph paper. Key components include: - **P Wave**: The first small upward deflection, representing atrial depolarization. - **QRS Complex**: The sharp, tall upward and downward deflections following the P wave, indicating ventricular depolarization. - **T Wave**: The moderate upward deflection after the QRS complex, representing ventricular repolarization. - **PR Segment**: The flat line between the end of the P wave and the start of the QRS complex. - **ST Segment**: The flat line following the QRS complex and before the T wave. - **TP Segment**: The flat line between the T wave and the next P wave. - **RR Interval**: The time between consecutive QRS complexes, used to measure heart rate stability.
