Pilocarpine	Muscarinic, Slow HR
Bethenecol	Muscarinic, slow HR
alpha-2 adrenergic agonists	Stimulate vagus, Slow HR
Cardiac Glycosides	Stimulate Vagus, Slow HR
Propranolol	Class 2 Antidysrhythmic, Non selective ß-adrenoreceptor antagonists, slow HR
Atenolol	Class 2 Antidysrhythmic, β-1 selective adrenoreceptor antagonist, slow HR
Pindolol	Class 2 Antidysrhythmic, Partial agonist, β-adrenoreceptor antagonist, slow HR
Atropine	Anti-muscarinic, Increase HR
Isoprenaline	Non-selective β-adrenoreceptor agonist, increase HR
Quinidine	Class 1a Antidysrhythmic, blocks fast NA+ channels, slows repolarization
Procainamide	Class 1a Antidysrhythmic, blocks fast NA+ channels, slows repolarization
Lignocaine	Class 1b Antidysrhythmic, blocks fast NA+ channels, accelerates re-polarization
Tocainide	Class 1b Antidysrhythmic, blocks fast NA+ channels, accelerates re-polarization
Amiodarone	Class 3 Antidysrhythmic, unknown mechanism
Verapamil	Class 4 Antidysrhythmic, calcium channel blocker
Diltiazem	Class 4 Antidysrhythmic, calcium channel blocker
Dobutamine	Positive inotrope: increases contractility, catecholamine, sympathomimetic β1-selective receptor agonist
Dopamine	Positive inotrope: increases contractility, natural noradrenaline precursor, sympathomimetic β-adrenoreceptor agonist
Milrinone	Positive inotrope: increases contractility, phosphodiesterase inhibitor, increases force without HR effects
