Your EKG waveform, which is discussed in the patent application, is a much more likely candidate for being uniquely identifiable than your heartbeat.
Yes, I agree that the electrical signals produced during ones heartbeat are much more likely to uniquely identify (authenticate) an individual than ones pulse.
