[Case report on a myocardial ischemia due to medical tocolysis with ritodrin (pre-par) (author's transl)].

In the 24 year old former competitive athelete tocolysis with ritodrin (pre-par) was started at 28 weeks gestation in her second pregnancy for premature labor. Diffuse cardiac ischemia occurred during the intravenous infusion of ritodrin. The betamimetic drug was the factor which started the myocardial ischemia as evidenced by the serial electrocardiograms. The importance of serial electrocardiograms during treatment with ritodrin is emphasized.
