Question: Which part of the ECG corresponds to ventricular depolarization?
Options:
P wave
QRS complex
T wave
U wave
Correct Answer: QRS complex
Solution:
The QRS complex on an ECG represents the depolarization of the ventricles, leading to their contraction.

Questions & Step-by-Step Solutions
Which part of the ECG corresponds to ventricular depolarization?
Step 1: Understand what an ECG is. An ECG (electrocardiogram) is a test that measures the electrical activity of the heart.
Step 2: Learn about the different parts of the ECG. The ECG has several waves and segments, including the P wave, QRS complex, and T wave.
Step 3: Identify what depolarization means. Depolarization is the process where heart muscle cells become electrically activated, leading to contraction.
Step 4: Focus on the QRS complex. The QRS complex is the part of the ECG that shows the electrical activity as the ventricles depolarize.
Step 5: Conclude that the QRS complex corresponds to ventricular depolarization, which causes the ventricles to contract.
