A method for time-domain analysis of respiratory sinus arrhythmia

Abstract

Respiration-related heart rate variabilityrespiratory sinus arrhythmia (RSA) -is clearly related to vagal activity. Usually it is analysed in frequency domain. An improved method for the assessment of the RSA in timedomain is proposed and evaluated on a control group of 12 healthy volunteers (9 male, 3 female; age 31-70). The method is based on a measurement of respiration rate, combined with a reliable beat-to-beat heart rate determination. RR intervals of each respiration cycle are superimposed to obtain average RSA. The study of RSA in the time-domain can provide more information about the adaptation process and possible parasympathetic response of the heart, e.g. after heart surgery, because the shape of a typical RSA curve and its phase (relative to the measured breathing) are obtained. The time domain analysis of RSA is simple and does not need forced timing of respiration. We confirmed that the proposed methodology could be used in ambulatory and remote monitoring environments to follow the long-term changes in the RSA.

Mobile Healthcare Adoption among Patients in a Developing Country Environment: Exploring the Influence of Age and Gender Differences

“…Indeed, the e-healthcare phenomenon has already established its presence in healthcare sphere and has largely impacted healthcare systems to better achieve quality deliverables and outcomes to all users and parties involved in healthcare systems (Kaplan, 2008;Mayernik et al, 2010;Trobec & Stanic, 2011;Hill et al, 2012). Indeed, the new innovation of e-technologies has potentially achieved greater connectivity at the point of care where healthcare providers, healthcare professionals, and patients can leverage the best information and knowledge for better informing decision-making in the delivery of cost-effective healthcare (Gurman et al, 2012).…”

“…Indisputably, m-technology has revolutionized communication process within the healthcare environments and it is becoming more efficient in service delivery, seamlessly effective in improving joint function, cost-effective, adaptive to emergencies, quality-effective, responsive to changes, and overwhelmingly more simplified and streamlined (Mayernik et al, 2010;Trobec & Stanic, 2011;Gurman et al, 2012;Deloitte, 2014). Admittedly though, IT with its mighty computing capabilities has many miles to travel to achieve a specific satisfaction level in delivering the goods for healthcare systems.…”
