[Effects of parathyroid hormone and parathyroid hypertensive factor on myocardial mechanical properties in normotensive rats].
After a 10-minute incubation, both the parathyroid hypertensive factor (PHF) and parathyroid hormone (PTH) reduced myocardial contractility and accelerated myocardial relaxation. Effects of the PTH and PHF on myocardial inotropic characteristics were of opposite directions.
