如果听不到胎心会不会是胎儿发育不好?胎心一般在孕7周左右会出现,孕早期发现没有胎心,应该先冷静下来,换一家医院,或者在多等一两周再去检查,如果还是没有胎心,即可能是胚胎停育。导致胎停育的原因有很多,接触了有毒物质、受到放射线或大量电磁辐射的照射、服用了影响胚胎发育的药物、吸烟或酗酒等都是有可能会导致胎停育的。建议查清原因再对症治疗。<br>而孕中晚期发生的突然没有胎心,则有可能为胎儿缺氧所致,如脐带病变:脐带扭转、脐带脱垂等;胎儿因素:有畸形、胎儿宫内发育迟缓、感染、多胎等;母体病变:过期妊娠、妊高征、心血管疾病、中毒性休克等;胎盘因素:胎盘早剥、前置胎盘等。以上原因都会导致胎盘供氧不足,使胎儿缺氧死亡。建议孕妇一旦发现,就要立即到医院检查并接受相对应的治疗。
