| 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 |
