Jen, The name for the ultrasounds (level II, level III) have actually been abandoned and the correct term for a detailed perinatal ultrasound is a "targeted ultrasound" and should be the nomenclature used by everyone. As to the heart rate, it often appears slower when simply observing it and not listening. It was likely fine or the scan would have lasted longer than 20 minutes and the physician would have likely mentioned something... Lynn
