Final answer:
The deflection waves in an ECG tracing include the P wave, the QRS complex, and the T wave.
Step-by-step explanation:
The deflection waves in an ECG tracing include:
- The P wave: represents the depolarization of the atria.
- The QRS complex: represents the depolarization of the ventricles.
- The T wave: represents the repolarization of the ventricles.
These three waves provide important information about the electrical activity of the heart and can help identify cardiac conditions.
