What are the reasons for a slow heartbeat in a 4-and-a-half-month-old fetus?

Patient's question:

No

Doctor's answer:

Hello! How many times does the heartbeat occur per minute? At 4 months pregnant, the fetal heartbeat is slow, which may be due to fetal developmental issues or fetal distress. It is recommended to enhance nutrition, regularly receive oxygen, and closely monitor the fetal development.
