Misure di KV7 (KCNQ) canale attività di potassio in miociti isolati arteriosi (utilizzando tecniche elettrofisiologiche di patch clamp) in parallelo con misure di constrictor / dilatatore risposte (usando myography pressione) può rivelare importanti informazioni sul ruolo di KV7 canali in fisiologia vascolare muscolatura liscia e farmacologia.
