Abstract
Apparatuses, machine-accessible storage media, and methods for noninvasively measuring a heart performance metric, such as left ventricular filling pressure, are described. In an embodiment, the apparatus includes a housing shaped to be grasped by a hand; a tower protruding from a surface of the housing positioned to conform to a finger of the hand when grasping the housing; a tactile sensor disposed on a curved surface of the tower and adapted to measure blood pressure pulsatility in a digital artery of the finger and output pulsatility signals indicative of the blood pressure pulsatility; a graphical user interface for orchestrating a test of the performance metric of the heart and displaying results of the test.
