Combined effect of beating rate and hydrostatic pressure on excitation in cardiac muscle
cardiac heart rate hydrostatic animal dog
2009/7/16
Canine cardiac Purkinje fibers stimulated at frequencies from 1-4 Hz were exposed to hydrostatic pressures of 1 and 150 ATA. Both increases in stimulation frequency and pressure slowed conduction and ...
Hyperbaric exposures alter cardiac excitation-contraction coupling
Cardiac excitation-contraction electrocardiographic heliox hyperbaric
2009/7/16
Cardiac excitation-contraction (E-C) coupling variables were measured in anesthetized cats during helium-oxygen dives to 1000 fsw (305 msw). At constant pacing rates of 190-300/min the delay between o...
