title: Electrocardiographic changes induced by insertion of an intrauterine device and other uterine manipulations.
abstract: A prospective study was carried out in normal women in order to investigate the effects of the following procedures on the electrocardiogram and blood pressure: (1) insertion of an intrauterine device (IUD)--the Lippes loop, Tcu-200, uterine progesterone system or Cu-7; (2) endometrial biopsy; and (3) uterine flushing. In groups in which a large IUD like the Lippes loop and/or a stiff IUD like the Cu-7 was inserted, the frequency of bradycardia was significantly higher than in any other groups. The severity of the bradycardia was similar in all of the groups and the frequency of this alteration was also similar among the nulliparous women or in those who complained of pain during the instrumentation, irrespective of the type of IUD inserted or the procedure carried out. No alarming modifications of blood pressure were observed and maintaining the patients in the recumbent position was sufficient to alleviate symptoms. In severe cases use of the Trendelenburg position should be enough to correct any alterations.
