[Fetal bigeminus following combined bronchodilator treatment of the mother].
After a combined bronchodilatory treatment of theophylline and terbutaline an intermittant fetal bigeminus is observed. The cardiotoxic changes disappear after days when treatment is stopped. After delivery the child is healthy. The slow disappearance of the arrhythmia is a result of the prolonged half-life of theophylline in the fetus. A combined therapy for asthma should be avoided. If this is not possible, regular cardiologic controls of the fetus should be carried out.
