Abstract:

This paper provides insights into where and how to integrate textile inductive electrodes into a car to record optimal-quality respiratory signals. Electrodes of various shapes and sizes were integrated into the seat belt and the seat back of a driving simulator car seat. The electrodes covered various parts of the body: upper back, middle back, lower back, chest, and waist. Three subjects completed driving circuits with their breathing signals being recorded. In general, signal quality while driving versus sitting still was similar, compared to a previous study of ours with no body movements.

Abstract:

Background and purpose: A valid 12-lead electrocardiogram (ECG) depends on correct acquisition technique, particularly on the accurate location of precordial (chest) electrodes. The emergency medical services (EMS) segment of the care continuum is under-represented in previous clinically oriented studies of electrode placement. This study sought to assess the accuracy of chest electrode placement by EMS and clinical personnel in one geographic area, to identify patterns of misplacement to inform future training and continuing education, and to compare two methods of assessing electrode placeme

Abstract:

It has been suggested that esophageal recordings of the diaphragm electromyogram (EMGdi) are influenced by changes in chest wall configuration. Whether the changes are of physiological or artifactual origin is unclear. For example, the distance between the esophageal electrode and the diaphragm is likely to alter with chest wall configuration and may lead to misinterpretations of EMGdi. The aims of this study were 1) to evaluate and quantify the effect of the muscle-to-electrode (ME) distance filter on EMGdi, as obtained with a multiple-array esophageal electrode, 2) to take advantage of the M

Abstract:

Electrical impedance tomography (EIT) is a radiation-free and noninvasive medical image reconstruction technique in which a current is injected and the reflected voltage is received through electrodes. EIT electrodes require good connection with the skin for data acquisition and image reconstruction. However, detached electrodes are a common occurrence and cause measurement errors in EIT clinical applications. To address these issues, in this study, we proposed a method for detecting faulty electrodes using the differential voltage value of the detached electrode in an EIT system. Additionally

Abstract:

Continuous ECG monitoring can play an important role in the rapid detection of pathological signatures and arrhythmias. Current systems use electrodes with limitations in wearable long-term applications and spatial selectivity. In this work, two sizes of textile concentric ring electrodes (TCRE42 and TCRE50) were developed and tested for monitoring cardiac activity. The low-cost devices were found to be easy to implement and to potentially have the advantages of textile electrodes for being lightweight, stretchable, adjustable, washable, and long-lasting. Both TCREs yielded similar signal dete

Abstract:

Epidermal electrophysiology is widely carried out for disease diagnosis, performance monitoring, human-machine interaction, etc. Compared with thick, stiff, and irritating gel electrodes, emerging tattoo-like epidermal electrodes offer much better wearability and versatility. However, state-of-the-art tattoo-like electrodes are limited in size (e.g., centimeters) to perform electrophysiology at scale due to challenges including large-area fabrication, skin lamination, and electrical interference from long interconnects. Therefore, we report large-area, soft, breathable, substrate- and encapsul

Background. Determination of the thoracic fluid content in the dynamics is becoming increasingly common in clinical trials and is a promising method for monitoring patients of intensive care units of various profiles. The most affordable and cost-effective methods for monitoring the amount of fluid in the chest at present are those based on measuring the electrical impedance of the chest when scanning it with high-frequency current. These techniques provide good repeatability of results, and are virtually independent of the operator. The purpose of the work is to develop own original techniqu

A system of electrodes for a bioimpedance spectrometry device has been developed. This device measures the resistance of biological tissues for given frequencies of electric current. The device is able to assess the state of organs and tissues of biological structures in case of breast cancer, as well as under various external influences. It differs from all existing bioimpedance spectrometry devices in that it has small dimensions, is capable of changing the frequencies of the probing current and at the same time immediately fixing the impedance values, and the system of electrodes has a hemi

Abstract:

The usefulness of diaphragm electromyography recorded from an oesophageal electrode depends on a reliable signal which is free of artefact. The diaphragm EMG (electromyogram) recorded from chest wall surface electrodes may be unreliable because of signal contamination from muscle activity other than the diaphragm. Initially, the oesophageal electrode catheter for human studies had only one electrode pair, which could be difficult to position accurately and was influenced by a change in lung volume. Recently, a multipair oesophageal electrode has been developed which allows a high-quality EMG t

Intraoperative wireless interrogation is a useful monitoring method for the leadless pacemaker (LP); however, there are few reports on this technique. A 60-year-old woman underwent cardiac surgery 24 days after Aveir LP implantation. Considering the risk of intraoperative device dislodgment and pacemaker malfunction due to electromagnetic interference, the LP was monitored by wireless interrogation via body-surface electrodes, and no device dislodgement or pacemaker malfunction was observed during surgery.

Abstract:

If esophageal and chest wall recordings of diaphragmatic electromyographic activity (EMG) accurately reflect neural drive to this muscle, then compound muscle action potentials (CMAPs) produced by supramaximal stimulation of the phrenic nerve should not alter with changes in diaphragmatic position. Maximal CMAPs were therefore recorded 1) during changes in lung volume from near residual volume to near total lung capacity, 2) during isovolume maneuvers at different lung volumes, and 3) while subjects were lying, sitting, and standing. The areas of maximal CMAPs recorded with the gastroesophagea

Abstract:

External defibrillation involves short electric shocks of several thousand volts applied to the chest of patients suffering from heart stop. The shock coordinates disorganized muscle fibers of the heart which then can resume normal activity. Implanted pacemakers monitor the natural electrical activity of the heart via electrodes mounted permanently on the inside of the heart. If this activity is insufficient, the pacemaker stimulates the heart muscle by applying a short electrical impulse of a few volts. During the period of defibrillation, voltage differences arise simultaneously between vari

Clinical assessment of cardiac status can be difficult and incomplete without an assessment of fluid volume status, especially of the lungs. Now, a new parameter is available, thoracic fluid content (TFC). It is an indicator of total fluid volume, both intracellular and extracellular. Because it is measured noninvasively using impedance cardiography (ICG), it could be a welcome addition to the physician's assessment. An evaluation of TFC was performed beginning with 1) an examination of chest impedance (Z) as an accurate means of following fluid changes, 2) the relationship of TFC to Z using b

In the typical setting used at Sacré-Coeur Hospital [2], unipolar signals are collected by a set of electrodes positioned both on the epicardial surface (63 to 127 leads fixed to a sock pulled over the heart) and on the endocardial surface of the left ventricule (64 to 127 leads fixed on a balloon which is introduced th
