Heart rate variability - current diagnosis of the cardiac autonomic neuropathy. A review

Combination of Ewing test, heart rate variability, and heart rate turbulence analysis for early diagnosis of diabetic cardiac autonomic neuropathy

The aim of this study was to compare and analyze Ewing test, heart rate variability (HRV), and heart rate turbulence (HRT) in the diagnosis of cardiac autonomic neuropathy (CAN) in diabetic patients.Ninety diabetic patients (age 18-78) and 20 nondiabetic control subjects were studied. Standard Ewing test and 24-hour Holter was performed in all participants to evaluate CAN. Patients with Ewing s...

A Comparison of Nonlinear Measures for the Detection of Cardiac Autonomic Neuropathy from Heart Rate Variability

In this work we compare three multiscale measures for their ability to discriminate between participants having cardiac autonomic neuropathy (CAN) and aged controls. CAN is a disease that involves nerve damage leading to an abnormal control of heart rate, so one would expect disease progression to manifest in changes to heart rate variability (HRV). We applied multiscale entropy (MSE), multi fr...

Orthostatic Hypotension and Heart Rate Variability as Indicators of Cardiac Autonomic Neuropathy in Diabetes Mellitus

Aim: The aim of this study was to emphasize two different points in our work: 1) The well known importance of (subclinical) postural hypotension and reduced heart rate variability as (early) markers of autonomic neuropathy; 2) and the more controversial influence of diabetic control in their worsening. Methods: Two standard cardiovascular response tests (heart rate variability by respiration an...

Heart Rate Variability, Heart Rate Recovery, and Heart Rate Turbulence Represent Different Components of the Cardiac Autonomic Nervous System

Heart Rate Variability Analysis a Non-invasive Clinical Screening Tool to Detect Functional Ability of Diabetic Cardiac Autonomic Neuropathy

Cardiovascular complications are the main cause of death in people with diabetes, which if identified can lead to improved health. A non-invasive, clinical system for low-cost screening of diabetes mellitus (DM) is introduced and tested on patients with some known conditions. Data recorded on 20 Normal Control (NC) and 20 Diabetic mellitus. Lead II electrocardiogram (ECG) was recorded in three ...
