Inderal=beta blocker: Beta receptors=protein receptors for epinephrine & norepinephrine. Beta blockers=analogues which bind to beta receptors without stimulating them. We are always sending both slow-down (acetylcholine) & speed-up (epinephrines) to heart muscle cells. Heart rate=a result of intrinsic rates powerfully modulated by these neurotransmitters from brain. Beta blockers partially ↓ faster rates from brain.
