  1. *Hearts were collected at 24 h post-exposure to ENCF-1 and ENCF-4 PM.
  2. LVDP: left ventricular developed pressure, HR: heart rate, +dP/dtmax: maximum first derivative of change in left ventricular pressure/time, −dP/dtmin: minimum first derivative of change in left ventricular pressure/time.
