What are the key features of a normal ECG waveform?.
Model answer
What a good answer should say
- The key features of a normal ECG waveform include the P wave, QRS complex, and T wave.
- The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization.
Explanation
Why this works
This answer is strong because it accurately identifies and describes the main components of a normal ECG waveform, which is essential for understanding cardiac activity. The question tests the student's ability to recall and explain the significance of these features in the context of the cardiac cycle.
