Improvements in Accurate Detection of Cardiac Abnormalities and Prognostic Health Diagnosis Using Artificial Intelligence in Medical Systems

Abstract

This paper presents an approach of apt prognostic diagnostics of cardiac health by using Artificial Intelligence (AI) in safety-related based non-invasive bio-medical systems. This approach addresses the existing challenge in identification of the actual abnormality of the vital cardiac signal from the various interrupting factors like bio-signal faulted due to high noise signal interference, electronic and software fault, mechanical fault like sensor contacts failures, wear and tear of equipment. Presently, most of the medical systems use a 1oo1(one-out-of-one) system architectures, and there exists a safety procedure to raise a particular defined type of standard alarm for a specific failure to detect an abnormality. These existing approaches may incur high maintenance costs and subject to random failures with long downtimes of the system and where it affects operational safety to a certain extent. However, there is a scope to improve in the segregation of the actual fault-free signal and extract the abnormality of the vital feature for prognostic diagnostics. With advancements in systems engineering and usage of safety-related design architectures in medical systems, we used an Artificial Intelligence (AI) based approach in performing the data analytics on the selected correct vital signal for prognostic analysis. As a case study, we evaluated by configuring the system with the 2oo2 fault-tolerant safety-related design architecture and implemented the diagnostic function using the AI-based method on the apt logged data during system operation. The results show a substantial improvement in the accuracy of the cardiac health findings.

Risk management of smart healthcare systems: Delimitation, state-of-arts, process, and perspectives

“…117 Lakkamraju et al use artificial intelligence approaches in data analysis to identify the potential software and mechanical faults of medical systems for cardiac health. 118 We do not explain the terms in this subsection since there are too many keywords and algorithms, but we have not a complete review. Readers can reference the article by Hamet and Tremblay if they have interests in relevant topics.…”

Improvements in Medical System Safety Analytics for Authentic Measure of Vital Signs Using Fault-Tolerant Design Approach

“…However, considering these defined requirements and the implementation of the signal processing algorithms software, there is any inconsistency between the algorithms to extract the same vital sign parameter due to faults or limitations at a certain level. In the recent past, few experimental studies with varied sample parameter voting and data fusion methods were used (9,(12)(13)(14)(25)(26)(27)(28)(29) to better the safety of these devices. Additionally, few studies (14,21,22) reported that the same vital parametric data, like HR, can be realized with the different mediums of the sensor.…”
