Across 1. slow calcium channel blocker similar to verapamil, dilates coronary arteries 5. Calcium channel blocker that slow AV conduction; also dilates coronary arteries 6. Naturally occuring catecholamine that increases cardiac output 8. phenothiazine derivative similar to chlorpromazine with potent antiemetic properties and fewer side effects 10. Bronchodialator tha dries secretions 12. Increases cardiac contrations without increasing the rate 13. rapid acting cardiac glycoside used for CHF and rapid atrial dysrhythmias

Down 2. acts as a calcium channel blocker, acting as CNS depressant and anticonvulsant 3. Benzodiazepine antagonist - reverses the effects of benzodiazepines 4. Beta-adrenergic blocking agent that reduces heart rate, cardiac output, and blood pressure 7. Prolongs ventricular repolarization- 9. antidysrhythmic that prolongs the duration of the action potential, increases coronary blood flow 11. oderless, tastless, colorless gas essential for life
