The Baltimore Sun wrote that "the more extroverted demands of disco music have made Mr. Mayfield reveal a more dynamic approach to his music." The Jersey Journal said that Mayfield "brings his cool falsetto to some rather pedestrian disco." The Bristol Evening Post called Heartbeat "a typical album of work, intelligent, lyrical and richly satisfying." The Ottawa Citizen concluded that "songs like 'Victory' and 'Over the Hump' show that the ideas are still flowing and that they make their best points when Mayfield stays closest to his soul, rhythm and blues roots."
