In ECG, enlarged ventricles is represented by enlarged

Options

A. P wave
B. Q wave
C. R wave
D. T wave

Answer

To solve the question regarding which wave in an ECG represents enlarged ventricles, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Basics of ECG**:
- ECG stands for electrocardiography, which is a test that records the electrical activity of the heart over a period of time. It produces waves that correspond to different phases of heart activity.

2. **Identify the Waves in ECG**:
- The main waves in an ECG are P wave, Q wave, R wave, S wave, T wave, and sometimes U wave. Each wave represents different electrical activities in the heart.

3. **Connect the Waves to Heart Function**:
- The P wave represents atrial depolarization.
- The QRS complex (which includes Q, R, and S waves) represents ventricular depolarization.
- The T wave represents ventricular repolarization.

4. **Focus on Ventricular Enlargement**:
- Ventricular enlargement (also known as ventricular hypertrophy) affects the electrical activity of the heart, particularly during the depolarization phase represented by the QRS complex.

5. **Identify the Correct Wave for Ventricular Enlargement**:
- Among the waves that represent ventricular depolarization, the R wave is particularly significant. An enlarged ventricle will typically show an increased amplitude in the R wave on the ECG.

6. **Conclude with the Correct Answer**:
- Therefore, in the context of the question, enlarged ventricles are represented by an enlarged R wave in the ECG.

### Final Answer:
The correct option is **C) R wave**.
