Increased afterload induces pathological cardiac hypertrophy: a new in vitro model.

abstract：:Increasing the frequency of steady state stimulation increases the rate of mechanical restitution in hypothermic (27 degrees C) guinea pig papillary muscles. In this paper we have investigated the influences of the calcium antagonist nifedipine and of reduced extracellular calcium concentration on this phenomenon. We ...
