From: Carbon monoxide affects electrical and contractile activity of rat myocardium
Changes in configuration of electrical and contractile activity of atrial myocardium induced by CO. Representative original traces of (a) action potentials (APs) in spontaneously beating right atrial preparations and (b) contraction curves in paced (0.1 Hz) stripes of working right atrial myocardium during control conditions and 300 µM CO. Relationship between decrease in (c) AP duration (APD) and (d) contractile force and the time of CO application-data from separate representative experiments. The black arrow indicates the moment of CO application.
