Using the palmar surface of the hand at the base of the fingers (also known as the ball of the hand), locate the cardiac landmark and palpate the area for thrills. A thrill is a palpable vibration that feels like the throat of a purring cat. The finger pads of all five fingers are used to examine for pulsations. Neither the ulnar aspect of a closed fist nor the fingertips along with a stethoscope as a guide is used to palpate the cardiac landmarks.
