by means of rapid planar hill type antimony-bismuth thermophiles the initial heat liberated by papillary muscles was measured synchronously with developed tension for control ( c ) , pressure-overload ( gop ) , and hypothyrotic ( ptu ) rat myocardium ( chronic experiments ) and after application of 10 ( -6 ) m isoproterenol or 200 10 ( -6 ) m udcg-115 .
