Raspberry leaf infusion and fetal heart rhythm disturbances

Abstract

Fetal cardiac arrhythmias and conduction disorders represent the second most commonly identified issue within the circulatory system. Extrasystoles make up 80% of all prenatal arrhythmias, whereas tachyarrhythmias account for 10% and bradyarrhythmias range from 5-10%, making them less prevalent. The diagnosis of the specific type of arrhythmia is conducted through echocardiography. A 27-year-old woman, who was in the 38th week of a normal pregnancy, was referred to the Medical University of Lublin's Department of Obstetrics and Pathology of Pregnancy for a fetal echocardiography exam. The expectant mother consumed a daily infusion of raspberry leaves, totaling 3-4 cups (330 ml). Raspberry ketone (RK) is under investigation for its potential heart protective effects; however, there is no established safe dosage prior to delivery. After discontinuing the treatment, the fetal heart rate returned to a normal rhythm. This study is the first to link raspberry consumption with occurrences of fetal arrhythmias. Effective diagnosis of fetal heart rhythm disturbances relies on comprehensive echocardiography of the fetal heart and thorough interviewing of the pregnant patient. Premature delivery due to fetal heart rhythm issues, without a detailed analysis via echocardiography, is a significant oversight.
