Stimulating a human heart with mechanical ultrasonic vibration at 300 kc to 2.5 mc. Unfortunately the writeup doesn't say what the heart actually did, but the diagram claims to show a beat in response to the vibration. 300k is WAY above any frequencies in the nervous system, so this can't be an expected response.
I don't think anyone followed up on this. It might be useful to see if hearts are affected by magnetostriction induced by RF fields. Lots of iron in blood!
Best part: The experimenter who applied mechanical vibration to a heart was Dr Newton Harvey. Can't beat it.
