Propanolol can be used in all of the following conditions EXCEPT:
**Core Concept**
Propranolol is a non-selective beta-blocker that works by competitively inhibiting the binding of catecholamines (such as epinephrine and norepinephrine) to beta-adrenergic receptors in the body. This leads to a decrease in heart rate, contractility, and cardiac output.
**Why the Correct Answer is Right**
Propranolol is often used in conditions such as hypertension, angina pectoris, and certain types of arrhythmias, including supraventricular tachycardia. It is also used to reduce the risk of myocardial ischemia and infarction in patients with coronary artery disease. Additionally, propranolol has been used to prevent migraine headaches and to reduce the symptoms of performance anxiety.

**Clinical Pearl / High-Yield Fact**
