Key result
Potassium channel blockers show considerable promise as antiarrhythmic drugs, with a lower and more predictable risk of serious proarrhythmia (1-3%) compared to class I agents.
Why the study?
Do potassium channel blockers effectively suppress cardiac arrhythmias with an acceptable safety profile compared to sodium channel blockers?
Do potassium channel blockers effectively suppress cardiac arrhythmias with an acceptable safety profile compared to sodium channel blockers?
Potassium channel blockers represent a promising therapeutic approach for cardiac arrhythmias with potentially better efficacy and a more predictable safety profile than class I agents.

Selective IKr blockers may advance antiarrhythmic options; leaves open clinical efficacy and safety.
Colatsky et al. (1994) conducted a review in Cardiac arrhythmias. Potassium channel blockers (Class III antiarrhythmic drugs) vs. Sodium channel blockers (Class I agents) was evaluated. Potassium channel blockers show considerable promise as antiarrhythmic drugs, with a lower and more predictable risk of serious proarrhythmia (1-3%) compared to class I agents.
