Participants heard 5-s excerpts either at the original pitch level or shifted upward or downward by 1 or 2 semitones. They successfully identified the original pitch level...

Good Memory or Delayed Response?

The action potential duration (APD) of ventricular myocytes depends on the length of the preceding diastolic interval (DI) in a relationship termed “electrical restitution.” The APD shortens with decreasing cycle length and thus with decreasing DI.1 The teleological advantage of this phenomenon is that it provides increased time for excitation-contraction coupling at long cycle lengths while pr...
