  • Interesting fact: The first known heart medicine was discovered in an English garden. In 1799, physician John Ferriar noted the effect of dried leaves of the common foxglove plant, digitalis purpurea, on heart action. Still used in heart medications, digitalis slows the pulse and increases the force of heart contractions and the amount of blood pumped per heartbeat.
    • n heartbeat A pulsation of the heart, including one complete systole and diastole, corresponding to that motion in the arteries called the pulse.
    • n heartbeat Hence Figuratively, a thought; an emotion, especially one that is tender or sad; a pang; a throb or throe of feeling.
