1 The performance of traditional biometric identification systems is as yet unsatisfactory in certain 2 fields of application. For this reason other physiological or behavioral characteristics are recently be3 ing considered, using new electrical or physical signals linked to a person’s vital signs. This paper 4 examines the biometric characteristics of PCG (PhonoCardioGram) signals from cardia...

A 57-year-old man presented to our emergency department with altered mental status. He had a past medical history significant for cirrhosis and previous placement of a transjugular intrahepatic portosystemic shunt (TIPS). On cardiac auscultation, a new heart murmur and an unexpected degree of cardiac ectopy were noted. On the 12-lead electrocardiogram, the patient was noted to have multiple pre...

CLINICAL INTRODUCTION A 57-year-old woman presented to our clinic with breathlessness brought on while walking uphill. She had been recently diagnosed with systemic hypertension. There was no known family history of cardiac disease, or prior smoking habit. On examination, pulse was 73 bpm and blood pressure 155/73 mm Hg, which was asymmetrical in her arms. Auscultation revealed a readily audibl...

At every annual exam, the primary care physician uses a stethoscope to listen for cardiac abnormalities. This approach is non-invasive, inexpensive, and fast. It is also highly unreliable. Over 80% of the people referred to cardiologists as suffering from the most commonly diagnosed condition, mitral valve prolapse (MVP), do not have this condition. Working in conjunction with cardiologists at ...

Cardiac auscultation is the examination of heart by listening to sound produced through a stethoscope. Heart sounds can provide information about functioning valve condition as well structural abnormalities heart. However, it needs intensive training for mastering. The objective work was develop an algorithm signal classification applied computer-assisted digital in order identify pathological ...

<span>Auscultation training devices are needed by teachers and students in health schools to practice auscultation techniques. In this paper, a low-cost IoT-based device has been developed using NodeMCU, four proximity sensors, metal as stethoscope, switch, an android smartphone, earphone, phantom doll. The message queuing telemetry transport (MQTT) protocol used for data communication be...

475 The Editor, A 48‐year‐old woman presented with shortness of breath on routine activities for 6 months. On cardiac auscultation, an ejection systolic murmur was heard at the upper left sternal border with wide and fixed splitting of the second heart sound. Electrocardiogram (ECG) was suggestive of normal sinus rhythm with right‐axis deviation, incomplete right bundle branch block (RBBB), and...
