Removal the electromyographic (EMG) noise is particularly challenging due to its spectral overlap with QRS complex. The existing EMG-denoising algorithms often distort signal morphology, thus obscuring diagnostically relevant information. xmlns:xlink="http://www.w3.org/1999/xlink">Methods:</i>...
Early coronary occlusion detection by portable personal device with limited number of electrocardiographic (ECG) leads might shorten symptom-to-balloon time in acute syndromes. The purpose this study was to compare the accuracy using vectorcardgiographic analysis a near-orthogonal 3-lead ECG configuration suitable for credit card-size integration automated and human 12 lead interpretation. 12-lead ECGs 3 additional ("abc") 2 arm left parasternal electrodes were recorded 66 patients...
Abstract Wearable smart monitors (WSMs) applied for the estimation of electrophysiological signals are utmost interest a non-stressed life. WSM which records heart muscle activities could signalize timely life-threatening event. The typically recorded across at surface body; hence, monitor requires high-quality electrodes. electrodes used in clinical settings [i.e. silver/silver chloride (Ag/AgCl) with gel] not practical daily out clinic usage. A application dry electrode stable and...
Non-invasive ventilation performed through an oronasal mask is a standard in clinical and homecare mechanical ventilation. Besides all its advantages, inevitable leaks the cause errors feedback information provided by airflow sensor and, hence, patient-ventilator asynchrony with multiple negative consequences. Here we investigate new way to provide trigger ventilator. The method based on measurement of rib cage movement at onset inspiration during breathing fibre-optic sensors. In series...
Clinical outcomes of several acute conditions, including myocardial infarction (MI), the most common cause death, can be improved by timely diagnostics based on electrocardiography (ECG). However, current diagnostic technologies include a large number wired ECG electrodes, which require accurate placement trained personnel. The ideal device would suitable for self-measurement, i.e., have small mobile or portable, and provide an diagnosis. these aims not been met using same device. A recently...
ECG measurements at rest are susceptible to different kinds of noise which may affect clinical interpretation. Unlike the low-frequency body movements or spectrally well-defined power line interference, broadband electromyographic (EMG) coincides with QRS complex, makes its removal particularly challenging. While a number algorithms have been developed, their evaluation and comparison long remained challenging due lack database EMG-contaminated genuine noise-free signals. We recently...
Introduction: Early prehospital chest pain assessment improves acute coronary syndrome (ACS) outcomes and can reduce unnecessary Emergency Room (ER) visits but requires medical personnel electrocardiographic (ECG) equipment. Objective: To evaluate the feasibility of a personal credit-card sized self-assessment device (HeartBeam, Santa Clara, CA, USA) in diagnosing ACS. Methods: ACS risk was estimated by serial likelihood ratio analysis 3 components: pre-existing heart disease (CHD)...
Background: The multiple electrodes needed to generate a 12-lead electrocardiogram (12L ECG) limits its use traditional health care settings. An innovative credit-card sized unit (HeartBeam, Santa Clara, CA, USA) when placed on the chest without cables captures vectorcardiogram (VCG). A personalized transformation matrix (PTM) then converts signals into 12L ECG. Objective: This is first quantitative (standard intervals and amplitudes) qualitative (rhythm diagnosis) accuracy assessment of...
Acute myocardial infraction (AMI) is a leading cause of death in the developed countries. Survival patients having acute coronary syndrome (ACS) dramatically depends on treatment delay. Hence, technology that would enable ECG recording immediately after ACS symptom occurrence may significantly decrease AMI mortality. In this study we investigate signal quality reconstructed 12-lead ECGs by using 3-lead handheld device with dry electrode realistic ambulatory conditions. For each subject...
