A novel portable wireless heart sound monitoring system that can help the healthcare professional monitor the heart sounds of multiple patients is presented in this study. This system will allow a single healthcare professional to monitor the heart sounds of a large number of patients, as and when needed and thus significantly improve the quality of healthcare available to the patients and at the same time drastically reducing the need for making frequent rounds to the patients’ bedsides. The proposed system employs GA-optimized wavelet based denoising to ensure that the heart sounds received by the healthcare giver is as free from noise as possible. The proposed system is empirically validated on a total of 2560 heart sound signals. The results indicate that the proposed system is indeed capable of being an asset to healthcare providers in improving the quality of healthcare that they can provide.
