Not exactly a medical malapropism, but perhaps permissible. In some cases of very severe heart valve damage, leakage causes powerful eddy currents and vibrations that can be felt by the doctor's hand over the heart, and is called " a thrill." At a large city teaching hospital, over a hundred medical students were lined up to take turns palpating the precordium of such a female patient. The fiftieth student, bored by the long wait for his turn, put his hand in the wrong place, and said to the guy behind him. "I don't get any thrill." The outraged patient jumped out of bed and locked herself in the toilet.
