Lightweight Denoising Autoencoder Design for Noise Removal in Electrocardiography

IEEE Access, 2022
This study proposes two denoising autoencoder models with discrete cosine transform and discrete wavelet transform, to remove electrode motion artifacts in noisy electrocardiography. Initially, the discrete cosine transform and discrete wavelet transform

Transient ischemic attack and acute ischemic stroke: evidence of altered corrected index of cardiac electrophysiological balance

Frontiers in Neurology
BackgroundSeveral electrocardiogram (ECG) abnormalities have been reported in patients with acute cerebral ischemic events. The index of cardiac electrophysiological balance (iCEB) and corrected index of cardiac electrophysiological balance (iCEBc) are ...

Intracardiac electrocardiography

The Turkish Journal of Pediatrics, 1963
Keith⁰ in 1956 showed that the deaths from congenital heart disease occur chiefly in the first year of life. Cardiac surgery has advanced rapidly and provided a constant stimulus to the development of precise diagnostic methods. Cardiac catheterization

Computer-aided electrocardiography [PDF]

, 1987
The three principal forms of medical electrocardiography are the standard 12 lead electrocardiogram (ECG), the exercise ECG and the long-term ambulatory ECG. The volume of use of the 12 lead ECG is 10 to 20 times greater than that of the exercise test or

Examination of Electrocardiography and 24-Hour Holter Electrocardiography Data of Children Presenting With the Complaint of Palpitation.

Van Tıp Dergisi, 2021
INTRODUCTION: Introduction: Palpitations are the most common and most important symptoms of patients with rhythm disturbances. Rhythm disturbances may not be detected by electrocardiography.

Diagnostic utility and predictive ability of electrocardiography in detecting myocardial abnormalities in cardiac magnetic resonance imaging [PDF]

Background: The role of electrocardiography (ECG) to screen for cardiac sequelae on cardiac magnetic resonance imaging (CMR) in COVID-19 infection is unclear. This study examined the burden of CMR abnormalities (e.g.

A multicenter study on the diagnostic value of ankle brachial index combined with pulse volume wave parameters for peripheral arterial disease

Frontiers in Cardiovascular Medicine
ObjectiveTo evaluate the significance of incorporating all pulse volume wave parameters, such as the inter-arm systolic blood pressure disparity, inter-leg systolic blood pressure difference, proportion of mean arterial pressure, and upstroke time, into ...

The Gut–Heart Axis in Systemic Sclerosis: Evidence From a Large Prospective Early Disease Cohort

Arthritis Care &Research, EarlyView.
Objective Cardiac involvement significantly impacts prognosis in systemic sclerosis (SSc), highlighting the need for early risk stratification. Gastrointestinal (GI) symptoms are common and often manifest early. Emerging data suggest a link between GI and cardiac manifestations, possibly through shared mechanisms like dysautonomia.
