Embodiment Construction

[0041] The present invention relates to a system and method for continuous monitoring of heart activity via a mobile device, and an algorithm for detecting cardiac abnormalities based on readings on an electrocardiogram (ECG) and phonocardiogram (PCG).

[0042] Some abnormalities of heart sounds occur occasionally or irregularly. Therefore, during a diagnosis, the doctor may not be able to catch or hear it. The diagnostic procedure using a stethoscope is performed at different locations on a person's chest to identify or classify different heart sounds (S1, S2, S3 or S4). This process is difficult to automate. In addition, there is no device for monitoring heart sounds because an experienced doctor is required to listen to heart sounds.

[0043] These challenges hinder not only diagnosis, but also telehealth deployments for remote or at-home monitoring of cardiac patients. This in turn puts a heavy burden on the healthcare system, as many people are hospitalized each year f...

Abstract

The invention relates to a system and method for continuously monitoring the heart activities via a mobile device and an algorithm to detect the heart anomalies based on the readings on electrocardiogram (ECG) and phonocardiogram (PCG). The system includes an integrated ECG and PCG apparatus which comprises a housing having a top part and a bottom part, wherein the bottom of the housing includes atapered surface extending from a perimeter of a bottom surface to an opening at the top of the bottom part forming an acoustic chamber; a power source housed within the top part; an audio receiver arranged to seal the opening for obtaining PCG signal; a plurality of dry sensors arranged at the bottom surface for obtaining ECG signal; a processing unit powered by the power source and communicatively connectable to the audio receiver and the plurality of dry sensors, the bottom of the housing is adaptably configured to create a snug fit on a subject to prevent the audio receiver from picking the acoustic noise from the outside of the acoustic chamber.

Description

technical field [0001] The present invention relates to a system and method for continuous monitoring of heart activity via a mobile device, and an algorithm for detecting cardiac abnormalities based on readings on an electrocardiogram (ECG) and phonocardiogram (PCG). Background technique [0002] Heart failure is a prevalent public health problem worldwide and poses a huge burden on overall healthcare costs. At least 5 million Americans live with heart failure, and approximately 550,000 new cases are diagnosed each year in the United States alone. In fact, heart disease accounts for 30% of deaths worldwide and will continue to be the leading cause of morbidity and mortality worldwide in the coming years. The first step in evaluating the cardiac system after taking a detailed history is a physical examination. Cardiac auscultation, or listening to heart sounds, is at the heart of a cardiac examination. Cardiac auscultation provides important initial clues for patient asse...
