Paroxysmal supraventricular tachycardia antiarrhythmics

FIGURE 6-2. Algorithm for the treatment of acute (top portion) paroxysmal supraventricular tachycardia and chronic prevention of recurrences (bottom portion). Note For empiric bridge therapy prior to radiofrequency ablation procedures, calcium channel blockers (or other atrioventricular [AV] nodal blockers) should not be used if the patient has AV reentry with an accessory pathway. (AAD, antiarrhythmic drugs AF, atrial fibrillation AP, accessory pathway AVN, atrioventricular nodal AVNRT, atrioventricular nodal reentrant tachycardia AVRT, atrioventricular reentrant tachycardia DCC, direct-current cardioversion ECG, electrocardiographic monitoring EPS, electrophysiologic studies PRN, as needed VT, ventricular tachycardia.)...

Adenosine reduces heart rate and AV conduction, although it is not a calcium antagonist. It is administered intravenously for the acute treatment of paroxysmal supraventricular tachycardia. Adenosine displays a rapid onset and short duration of action. Apart from its antiarrhythmic activity it is also a vasodilator, in particular in the coronary system. [Pg.341]

Flecainide, is an antiarrhythmic agent that is indicated for prevention of paroxysmal supraventricular tachycardia including atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardia, and paroxysmal atrial fibrillation and flutter (see also Figure 84). [Pg.273]

Quinidine (200 to 600 mg t.i.d.), a cinchona alkaloid with antiarrhythmic properties, is indicated in premature atrial, AV junctional, and ventricular contractions paroxysmal atrial (supraventricular) tachycardia paroxysmal AV junctional rhythm atrial flutter paroxysmal and chronic atrial fibrillation established atrial fibrillation when therapy is appropriate paroxysmal ventricular tachycardia not associated with complete heart block and maintenance therapy after electrical conversion of atrial fibrillation or flutter (see Figure 103).
