Key result
New Class III antiarrhythmics show moderate efficacy but require further long-term safety data on Torsades.
Why the study?
The clinical usefulness of new Class III antiarrhythmic drugs has not yet been sufficiently proven, and new issues such as reverse use-dependence and Torsades de Pointes have emerged.
Highlights the need for further clinical trials to accurately assess the efficacy and safety profiles, including risks like Torsades de Pointes, of new Class III antiarrhythmic drugs.
New Class III agents should not yet alter practice; leaves open long-term efficacy and TdP risk for prospective trials.

Katoh et al. (1995) conducted a review in Ventricular and Supraventricular Arrhythmias. New Class III Antiarrhythmic Drugs was evaluated. New Class III antiarrhythmic drugs show moderate efficacy for arrhythmias, but their long-term benefits and safety, particularly regarding reverse use-dependent block and Torsades de Pointes, require further investigation.
