When your heart beats too fast And the pressure's too high There's a class of drugs That catches your eye They calm the storm from the inside out Beta blockers — that's what we're talking about Beta blockers – do you know? Metoprolol, bisoprolol Atenolol, carvedilol Propranolol takes control Beta blockers – do you know?

Then remember the name Propranolol can make the airways strain Carvedilol goes broader still Beta blockade with alpha skill Vasodilation, pressure downhill Lower blood pressure — that’s the deal Beta blockers – do you know? Metoprolol, bisoprolol Atenolol, carvedilol Propranolol takes control Beta blockers – do you know? Don’t stop them cold – taper down slow Rebound hypertension – that’s the risk you know In bradycardia or asthma – think twice Check the contraindications – that’s good advice Beta blockers slow the pace Less force, less strain, a calmer space Less oxygen demand, less cardiac strain That’s why in angina they ease the pain Beta blockers – do you know?
