in left ventricular tissue , as a group , action potential duration at 50 % repolarisation ( apd50 ) was reduced in myopathic hearts ( 201+/-6 ( sem ) vs 228+/-9 ms in controls . p less than 0.01 ) , while the maximum rate of phase 0 ( dv/dtmax ) action potential amplitude , diastolic resting membrane potential and action potential duration at 90 % repolarisation ( apd90 ) did not differ from control turkeys .
