Which of the following antiarrhythmic drugs can develop Long QT syndrome?
Ans. is 'd' i.e., All the above Proarrhythmic Manifestations of Most Frequently Used Antiarrhythmic AgentsDrugCommon Proarrhythmic ToxicityAmiodarroneSinus bradycardia, AV block, increase in defibrillation thresholdRare: long QT and torsades des pointes,1:1 ventricular conduction with atrial flutterAdenosineAll arrhythmias potentiated by profound pauses, atrial fibrillationDigoxinHigh - grade AV block, fascicular tachycardia, accelerated junctional rhythm, atrial tachycardiaDisopyramideLong QT and torsades des pointes, 1:1 ventricular responses to atrial flutter; increased risk of some ventricular tachycardias in patients with structural heart diseaseDofetilideLong QT and torsades des pointesDronedaroneBradyrrhythmias and AV block, long QT and torsades des pointesFlecainides1:1 Ventricular response to atrial fluter; increased risk of some ventricular tachycardias in patients with structural heart disease; sinus bradycardiaIbutilideLong QT and torsades des pointesProcainamideLong QT and torsades des pintes 1:1 ventricular response to atrial fluter; increased risk of some ventricular tachycardias in patients with structural heart diseasePropafenone1:1 Ventricular response to atrial flutter; increased risk of some ventricular tachycardias in patients with structural heart disease; sinus bradycardiaQuinidineLong QT and torsades des pointes, 1:1 ventricular response to atrial flutter; increased risk of some ventricular tachycardias in patients with structural heart diseaseSotalolLong QT amd tprsades des pointes, sinus bradycardia
