Prolonged P-R interval in ECG indicates:

• A. Tachycardia
• B. Myocardial infarction
• C. Bradycardia
• D. Hyperkalemia

Hint:

A prolonged P-R interval is usually seen in conditions such as heart block, which is often associated with bradycardia.

The Correct Option is C

- A prolonged P-R interval on an ECG typically indicates bradycardia, a condition in which the heart beats slower than normal.
- Tachycardia, myocardial infarction, and hyperkalemia do not generally cause a prolonged P-R interval.
