Which of the following is the diagrammatic representation of standard electrocardiogram (ECG)?

Options

A.
B.
C.
D.

Answer

To determine which of the provided options is the correct diagrammatic representation of a standard electrocardiogram (ECG), we can follow these steps:

### Step 1: Understand the Components of an ECG
An electrocardiogram (ECG) is a graphical representation of the electrical activity of the heart. The standard ECG consists of several key components:
- **P Wave**: Represents atrial depolarization.
- **QRS Complex**: Represents ventricular depolarization.
- **T Wave**: Represents ventricular repolarization.

### Step 2: Analyze the Options
Given multiple options, we need to analyze each one to identify which correctly displays the P wave, QRS complex, and T wave in the correct order and orientation.

### Step 3: Identify the Correct Option
- **Option 1**: Check if it shows P, QRS, and T in the correct sequence and shape.
- **Option 2**: Check if it has the P wave, QRS complex, and T wave correctly represented.
- **Option 3**: Analyze if it has the correct components and their arrangement.
- **Option 4**: Confirm if it accurately represents the standard ECG pattern.

### Step 4: Conclusion
After analyzing the options, we find that **Option 4** is the correct representation of a standard ECG, as it accurately displays the P wave, QRS complex, and T wave in the correct order and orientation.
