HintDrug or Class of DrugExtra Hint
Will block vagal stimulation of heart, decreases HR via SA node; may also be increased conduction velocity in AV nodeClass IA Na Channel Blocker
Prolong the AP and ERP of purkinje and muscle fibers; have become first line agentsClass of Drug
Will suppress ventricular ectopic foci and will decrease automaticity of purkinge fibers; shortens duration of AP and ERP; acts on activated and inactivated Na channels; IV adminClass IB Na Channel Blocker
Purine nucleoside used for terminating paroxysmal supraventricular tachacardia; increases K conductance leading to hyperpolarization; has Ca channel blocking effects; IV adminOther
Used for treatment of supraventricular arrhythmias; blocks Na channels and reduces phase 0 depolarization; slows of conduction in the His-Purkinje systemClass IC Na Channel Blocker
Will increase HR and contractility in response to increased sympathetic input; used primarily with supraventricular arrhythmiasClass of Drug
1 of 4 Beta BlockersBeta Blocker
Decreased automaticity and responsiveness while refractoriness is increased; longer duration of action and less antimuscarinic activity than quinidineClass IA Na Channel Blocker
Used IV for acute termination of atrial fibrillation or atrial flutter; Tosades de Pointes occurs in 3-8% of patientsK Channel Blocker
Used to reduce ventricular response to atrial flutter or fibrillation by slowing conduction through AV nodeClass of Drug
HintDrug or Class of DrugExtra Hint
A Ca channel blockerCa Channel Blocker
Blocks Na channels, and also Ca channels and beta-AR; oral admin and hepatic metabolismClass IC Na Channel Blocker
Myocardial depressants; reduce automaticity, responsiveness, and refractoriness; are particularly effective with ectopic foci and reentrant arrhythmias; 'local anesthetic action'Class of Drug
Usually for patients that can’t tolerate other type IA drugs; is a potent antimuscarinic drug; most side effects stem from antimuscarinic activityClass IA Na Channel Blocker
Blockade of rapid Na channels; effective primarily on ventricular arrhythmiasClass of Drug
Will slow conduction in His-pukinje system; used for atrial fibrillation or ventricular tachacardia; oral or IV adminK Channel Blocker
Effective in atrial and ventricular arrhythmias; more effective than quinidine, procaineamide, and mexilitine in preventing recurrence of ventricular arrhythmiasK Channel Blocker
Useful for atrial tachycardias, flutter or fibrillation because it slows conduction through AV node; inhibits Na/K ATPase and increases intracellular Ca concentrationOther
Potent antiarrhythmics for slowing the conduction of the cardiac impulseClass of Drug

We suppose D and E are already one-letter-hints right there, but we're willing to overlook that.
