SENSICARDIAC MOBI DIAGNOSTIC HEART MURMUR APPLICATION

The SensiCardiac Mobi Diagnostic Heart Murmur Application functions as a decision support system, designed to acquire and analyze acoustic heart signals to assist medical examiners in differentiating between physiological and pathological heart murmurs. This is achieved by employing a validated diagnostic algorithm through a mobile device and electronic stethoscope, demonstrating equivalent safety and effectiveness to its preceding device.

The SensiCardiac Mobi Diagnostic Heart Murmur Application by Diacoustic Medical Devices is a decision support system designed to acquire, record, and analyze heart sounds, aiming to help medical examiners distinguish between normal and pathological heart murmurs during auscultation. This system integrates a software application, the Sensi Diagnostic Heart Murmur Algorithm, which runs on a hosted server and interfaces with a handheld mobile device (e.g., iPhone 4S or later) and a compatible electronic stethoscope. It records acoustic heart signals at key auscultation positions, analyzing them to identify sounds like S1, S2, and suspected murmurs. Intended for use in clinical settings by physicians or trained personnel, it functions as a support tool, not a standalone diagnostic method, requiring physician oversight and consideration of other patient data. A direct comparison of the SensiCardiac Mobi with its predecessor, the Sensi Cardiac Diagnostic Heart Murmur Software, revealed that both systems utilize the identical Diagnostic Heart Murmur Algorithm and operate on equivalent computer platforms with the same electronic stethoscope interface. Both versions capture comparable patient information and demonstrate equivalent clinical performance, workflow, and graphical user interfaces, with the Mobi specifically adapted for mobile devices. Comprehensive verification and validation, including software validation and usability studies, confirmed that the SensiCardiac Mobi performs identically to its predecessor. Consequently, it was concluded that the SensiCardiac Mobi device is as safe and effective as the equivalent device and introduces no new safety or effectiveness concerns.
