A handheld auscultatory scanner (100) continuously obtains a heart sound signal from a patient, using a noninvasive passive acoustic sensor (102), allowing free-form protocol, analysis and display of the heart sound signal on a handheld processing unit (104) in a graphical manner such that a single heart cycle (200) is displayed in a synchronized manner, along with summary results (202,. 204, 206) of the processing of the acoustic signal. The results are presented in terms of standard auscultatory findings. The combination of summary findings, heart sound display and audible signal (110) provides a method for assisting in patient screening for heart conditions and for teaching auscultation techniques. |
