"Polygraphs current(ly) being used record people's breath, sweat and pulse rates, but the new machine will be able to count the number of heartbeats, they said."
A new scoring technique? "Mr. Smith, your heart beat 11,489 times during the course of this examination. You're being deceptive."
Am I missing something here? Don't most polygraphs in use today store and display the data on a laptop? And if they are recording pulse rate (being heartbeats per minute), why do they need a "total", if that is what this is?
