[The prognostic value of heart rate variety on congestive heart failure of pregnant women].

OBJECTIVE

To explore the prognostic value of heart rate variety (HRV) on congestive heart failure (CHF) of pregnant women complicated with organic heart disease.

METHOD: One hour ambulatary electrocardiography was performed in 61 pregnant women complicated with organic heart dieases at about the 28th-32th week in gestational period and 7 days after delivery respectively.

RESULT: 9 patients occured CHF later, their HRV time domain index were significantly decreased (P < 0.001, P < 0.05), compared with patients without CHF as control group. 7 days after delivery, When the condition of CHF patients was improved. Their SD, SD SD value increased.

CONCLUSION

HRV has some value of assessing the cardiac reserve and predicting the happen of Congestive Heart Failure in pregnant women complicated with organic heart disease.
