2–5 mcg/kg/min: Positive inotropy (mild chronotropy) — low dose cardiac support
5–10 mcg/kg/min: Strong inotropy — significant cardiac output augmentation
>10 mcg/kg/min: Strong inotropy + chronotropy — tachyarrhythmia risk increases
Clinical Notes: Indicated for acute heart failure, cardiogenic shock. Contraindicated in IHSS (hypertrophic obstructive cardiomyopathy) and uncorrected hypovolemia. Tolerance (tachyphylaxis) develops with prolonged use (>72h). Continuous cardiac monitoring required.
