Patients on those types of pumps (continuous flow LVADs) do actually have a pulse of their pump speed settings are properly set. The medical guidance is to set the pump speeds at a setting that allows the natural aortic valve to open once every few heartbeats. That makes it so the aortic valve doesn't calcify and get stuck shut. If they set the pump speed at that level the patients do still have a pulse, it's just a weak one.
