MINA: Multilevel Knowledge-Guided Attention for Modeling Electrocardiography Signals [PDF]
arXiv, 2019 Electrocardiography (ECG) signals are commonly used to diagnose various cardiac abnormalities. Recently, deep learning models showed initial success on modeling ECG data, however they are mostly black-box, thus lack interpretability needed for clinical usage.

Cryptanalyzing an image encryption algorithm based on autoblocking and electrocardiography [PDF]
IEEE MultiMedia, 2018, 2017 This paper analyzes the security of an image encryption algorithm proposed by Ye and Huang [\textit{IEEE MultiMedia}, vol. 23, pp. 64-71, 2016]. The Ye-Huang algorithm uses electrocardiography (ECG) signals to generate the initial key for a chaotic system and applies an autoblocking method to divide a plain image into blocks of certain sizes suitable ...

Deep Learning–Based Algorithm for Detecting Aortic Stenosis Using Electrocardiography
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020 Background Severe, symptomatic aortic stenosis (AS) is associated with poor prognoses. However, early detection of AS is difficult because of the long asymptomatic period experienced by many patients, during which screening tools are ineffective. The aim

Identification of weakly coupled multiphysics problems. Application to the inverse problem of electrocardiography [PDF]
Journal of Computational Physics, vol. 283, p. 271-298, 2015, 2015 This work addresses the inverse problem of electrocardiography from a new perspective, by combining electrical and mechanical measurements. Our strategy relies on the defini-tion of a model of the electromechanical contraction which is registered on ECG data but also on measured mechanical displacements of the heart tissue typically extracted from ...

Comparison of different electrocardiography with vectorcardiography transformations [PDF]
Italian National Conference on Sensors, 2019 This paper deals with transformations from electrocardiographic (ECG) to vectorcardiographic (VCG) leads. VCG provides better sensitivity, for example for the detection of myocardial infarction, ischemia, and hypertrophy.

A Primer of Electrocardiography [PDF]
Archives of Internal Medicine, 1961 This monograph is precisely what it is stated to be. It is an excellent elementary textbook which presents the fundamentals of electrocardiography in a concise and lucid manner. This book is designed for the beginning student, although it might be quite valuable for review by general practitioners and internists who see only limited numbers of tracings.

Relevance of increased negative T waves in apical hypertrophic cardiomyopathy with progressive myocardial damage: Insights from repeat cardiac magnetic resonance studies [PDF]
Radiology Case ReportsIn patients with apical hypertrophic cardiomyopathy (HCM), progressive electrocardiographic changes are observed during long-term follow-up. However, it is difficult to correspond these changes to the specific myocardial changes.

Current and Future Use of Artificial Intelligence in Electrocardiography
Journal of Cardiovascular Development and Disease, 2023 Artificial intelligence (AI) is increasingly used in electrocardiography (ECG) to assist in diagnosis, stratification, and management. AI algorithms can help clinicians in the following areas: (1) interpretation and detection of arrhythmias, ST-segment ...
