The ER is not specifically trained in obstetrics and while it's true that early in pg falling hcg levels indicate mscarriage, it is also normal for the levels to plateau or decline towards the end of the first trimester. At this point, your bebay still has a strong heartbeat and that's what is most indicative of a viable pregnancy. Honestly I'm surprised that they would even take hcg levels since they saw the heartbeat.
