If the blood flow in the wall of heart is inadequate due to obstruction of coronary artery in ECG and the ST segment is depressed which disorder is the person is suffering from

Options

A. Myocardialischaemia
B. Angina pectoris
C. Heart failure
D. Myocardial infraction

Answer

To solve the question regarding the condition associated with inadequate blood flow in the heart due to obstruction of the coronary artery, as indicated by a depressed ST segment on an ECG, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the ECG**:
- The ECG (electrocardiogram) consists of several waves: P wave, QRS complex, and T wave. The ST segment is the flat section between the end of the S wave and the beginning of the T wave.
- A depressed ST segment can indicate issues with the heart, particularly related to blood flow.

2. **Identifying the Condition**:
- The question states that there is inadequate blood flow due to obstruction of the coronary artery. This suggests that the heart muscle is not receiving enough oxygen-rich blood.
- The depressed ST segment is a critical indicator in diagnosing heart conditions.

3. **Evaluating the Options**:
- **Option 1: Myocardial Ischemia**: This condition refers to reduced blood flow to the heart muscle, but it is not the most specific answer to the symptoms described.
- **Option 2: Angina Pectoris**: This is characterized by chest pain due to temporary obstruction of blood flow to the heart muscle, often accompanied by a depressed ST segment during episodes of pain.
- **Option 3: Heart Failure**: This is a chronic condition where the heart cannot pump effectively, but it does not specifically relate to the ST segment depression.
- **Option 4: Myocardial Infarction**: This is commonly known as a heart attack, which usually presents with ST segment elevation rather than depression.

4. **Conclusion**:
- Based on the analysis of the options, the correct answer is **Angina Pectoris**. This condition is directly associated with the symptoms described in the question, including the inadequate blood flow and the depressed ST segment on the ECG.

### Final Answer:
The person is suffering from **Angina Pectoris**.
