Salidroside modulates repolarization through stimulating Kv2.1 in rats

Voltage-gated potassium (Kv) channel growth is strongly associated with the development of arrhythmia. Salidroside (Sal), an active component from Rhodiola crenulata, has been shown to exert protective effects against heart disease. The present study was conducted to investigate the effects of Sal on Kv2.1 channel, and to explore the ionic mechanism of anti-arrhythmic.
