RE:Medicine. A disordered rhythm of the heart characterized by three or four distinct heart sounds in each cycle and resembling the sound of a galloping horse. Also called cantering rhythm, gallop rhythm.

i read an account once, about a man, coming out of anethesia, after open heart surgury, who heard his doctor pronounce "gallopping heart".. a condition that is often fatal, since its hard to 'fix' with drugs..

but this man made a comlete recovery, and quickly.. in no time at all he heart rythm stabalized, and he was better.

at one of his check ups, he told his doctor, "I felt terrible as i started to wake up after surgury, but then i heard you say "gallopping heart" and knew i was a healty as a horse, and was going to be fine!"

interesting how what we hear, effects how we think!
