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

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

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 ...

Boundary‐Dependent Sleep–Wake Dysregulation in Idiopathic Hypersomnia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sleep state, consistent with ...

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.

Association of elevated albumin-corrected anion gap with all-cause mortality risk in atrial fibrillation: a retrospective study

BMC Cardiovascular Disorders
Background Compared to the conventional anion gap, the albumin-corrected anion gap (ACAG) offers a more precise measure of acid-base imbalance, providing superior prognostic insight.

Electrocardiogram P-Wave Dispersion and New-Onset Atrial Fibrillation: A Nested Case–Control Study

Reviews in Cardiovascular Medicine
Background: This study aimed to investigate the association between electrocardiogram (ECG) P-wave dispersion (Pd) in sinus rhythm and the risk of new-onset atrial fibrillation (NAF) within one year, to identify high-risk individuals ...
