A Case of Fetal Tachycardia after Electroconvulsive Therapy: A Possible Effect of Maternal Hypoxia and Uterine Contractions

Table 1

Results of fetal heart rate monitoring and duration of maternal apnea at each ECT session.

ECT	Stimulus (%)	Seizure duration, seconds	FHR, bpm	Duration of tachycardia, minutes	Uterine contraction	Maternal apnea, seconds
1	15	93	180–190	60	No	110
2	10	69	190–200	30	No	80
3	15	100	150	N/A	Yes (20 minutes)	20
4	25	25	180–190	Several	Yes (15 minutes)	20
5	25	38	150	N/A	Yes (10 minutes)	20
6	25	73	180–190	Around 120	Yes; (around 120 minutes)	20

All values except for seizure duration are approximate. ECT, electroconvulsive therapy; FHR, fetal heart rate; N/A, not applicable.
