The frequency of the heartbeat did not match Doyle’s. In fact, it didn't match any known biological organism on Earth. However, when the data was cross-referenced with pulsar frequencies from the Vela Pulsar, a match was found. The static on the tape wasn't interference; it was the "sound" of the Vela Pulsar, recorded in real-time, as if the microphone had been placed directly against the surface of the star.
