John Berryman's "The Right Time" (novelette, free): Psychics in medical diagnostics & surgery

One of the more unusual stories I've seen about folks with psychic powers - precision telekinesis, specifically: in medical diagnosis & surgery. In the process, we'll also get an introduction to the mechanics of heart attacks.

Fact sheet.

First published: Analog, December 1963.
Note: There is some confusion about who the real author is; John Berryman is apparently a pseudonym. Going by guesswork, real author is either Walter Bupp or Randall Garrett?
