Rationale 1: Beta blockers lower blood pressure, and can cause hypotension.
Rationale 2: Blockade of beta receptors in the heart can result in bradycardia, and hypotension can cause dizziness and possible fainting.
Rationale 3: Beta blockers slow heart rate, and can cause bradycardia.
Rationale 4: Blockade of beta receptors in the heart can result in bradycardia, and hypotension can cause dizziness and possible fainting.
Rationale 5: Beta blockers do not cause hyperkalemia.

Global Rationale: Blockade of beta receptors in the heart can result in bradycardia, and hypotension can cause dizziness and possible fainting.
