How many chambers in a lamprey heart?

The heart of a lamprey looks similar to that of modern fish in a sense. It is a two chambered heart with a single atrium and a single ventricle. The atrium of the heart is proceeded by a sinus venosus, which isn't considered an actual chamber but rather pre-heart chamber. Then after the ventricle we have a conus arteriosus that again isn't considered to be a chamber of the heart but rather a post-heart chamber. The blood flow through the heart is a one way path like that of modern day fishes.
