Abstract: Objective To evaluate the diagnostic value of tissue Doppler imaging (TDI) in classification of fetal arrhythmias, and conclude characters of each type of arrhythmias by analyzing wave forms of TDI. Methods Fifty-five fetuses suffered arrhythmia were included in study group. By comparing the results with control standard(M and PW), the sensitivity, specificity and reliability of TDI in diagnosis of fetal arrhythmias was calculated. At last, the character of waves by TDI of each type of arrhythmia was concluded. Fetal kinetocardiogram was made to identify the origin of arrhythmias. All cases were asked to perform electrocardiography and echocardiography examination after birth. Results The sensitivity, specificity and reliability of TDI was 98%, 100% and 100%, respectively. The character of atrioventricular waves and kinetocardiogram of 8 types fetal arrhythmias were conclude. Conclusions TDI has great value in classification of fetal arrhythmias.
