Adenosine (unclassified antiarrhythmics) | Antiarrhythmic (A1 receptor agonist) | A1 receptor agonist; activate K channels and inhibit CA channels | DOC of supraventricualr tachycardia | Bronchoconstriction, vasodilator, flushed appearance, chest pains (burning), strong SOB, flash of a headache, AV block (desired) |
Verapamil | Calcium Channel Blocker | Binds the Phenylalkylamine site on L-type Calcium channel | Drug of choice for supraventricular tachycardia | Multi-drug resistance, Ankle edema, Hypotension, Headache, Flushing Appearance, Cardiac Depression, Constipation, MI, cancer; Contraindicated in CHF |
