Problems solved by technology

However, in the PPG waveform, contrary to what is provided by the ECG signal, there is no specific information about the electromechanical activity of the heart, so that additional modules that distinguish normal from abnormal rhythms are required

Embodiment Construction

[0061] figure 1 An embodiment of an evaluation system 1 for evaluating a heart rate of a subject is shown schematically and exemplarily. The evaluation system 1 includes a PPG signal supply unit 10, a motion signal supply unit 20, a parameter supply unit 30, a heart rate determination unit 40, a rest period determination unit 50, a heart rate histogram determination unit 60, a heart rate distribution determination unit 70, and an abnormality determination unit 80 , an evaluation unit 90 and a feedback providing unit 100 . In this example, all units of the evaluation system 1 are contained within a housing 6 . However, in other examples, one or several of the units of the evaluation system 1 may also be provided remotely from the housing 6, such as at a central server, and communicate with the evaluation system 1 by any known wired or wireless means. Furthermore, in other examples, the evaluation system 1 is fully implemented as a unit within a computer system and must not in...

Abstract

The present invention relates to an assessing system, an assessing method and a computer program for assessing a heart rate of a subject, which find application in categorizing a physiological response as a condition, in particular in the diagnosis of pathological tachycardia and bradycardia. The assessing system comprises a photoplethysmography (PPG) signal providing unit (10); a motion signal providing unit (20); a parameter providing unit (30) for providing a subject specific parameter; a heart rate determination unit (40); a resting period determination unit (50); an abnormality determination unit (80) for determining an abnormality of the heart rate during the resting period; and an assessing unit (90) for assessing the determined abnormality based on the subject specific parameter. The invention provides a system and a method, which allow for a more reliable assessment of a heart rate of a subject based on a PPG signal of the subject.

Description

technical field [0001] The present invention relates to the assessment of a subject's heart rate. In particular, it relates to an evaluation system, an evaluation method and a computer program for evaluating a heart rate of a subject. Its application is to classify physiological responses into conditions, especially in the diagnosis of pathological tachycardia and bradycardia. However, it is to be understood that the present invention also finds application in other fields and is not necessarily limited to the applications mentioned above. Background technique [0002] A healthy adult heart typically beats within a specific frequency range during rest. Tachycardia (ie, heart rate that is too fast) or bradycardia (ie, heart rate that is too slow) can indicate a heart problem. [0003] Conditional assessment of heart rate from electrocardiogram (ECG) recordings can be done based on heart rate and rhythm and additionally ECG morphology. Employing a photoplethysmographic (PP...
