Abstract

V originále

Ajmaline decreased the upstroke velocity of action potential and action potential amplitude, increased the action potential duration measured at 50 and 90% repolarization, and reversibly inhibited most components of membrane ionic current in a concentration-dependent manner; IC50 was 27.8 umol/l for INa, 70.8 umol/l for ICa, 25.9 umol/l for Ito, 61.0 umol/l for IK, and 13.3 umol/l for IKATP.

In Czech

Ajmalin snizoval rychlost depolarizace akcniho napeti a amplitudu akcniho napeti, prodluzoval trvani akcniho napeti merene na urovni 50 a 90% repolarizace a reverzibilne inhiboval hlavni komponenty iontoveho membranoveho proudu v zavislosti na aplikovane koncentraci; IC50 byla 27.8 umol/l pro INa, 70.8 umol/l pro ICa, 25.9 umol/l pro Ito, 61.0 umol/l pro IK a 13.3 umol/l pro IKATP.
