Is transfusion in coronary artery surgery a predictor or a cause of reduced long-term survival? [PDF]

, 2020
Background Transfusion is common after coronary bypass surgery. Transfused patients present with higher operative risk and an increased hazard ratio for curtailed long-term survival. There is debate as to whether transfusion itself may further exacerbate

RawECGNet: Deep Learning Generalization for Atrial Fibrillation Detection from the Raw ECG [PDF]

arXiv, 2023
Introduction: Deep learning models for detecting episodes of atrial fibrillation (AF) using rhythm information in long-term, ambulatory ECG recordings have shown high performance. However, the rhythm-based approach does not take advantage of the morphological information conveyed by the different ECG waveforms, particularly the f-waves.

Physical activity and incidence of atrial fibrillation: A systematic review and meta-analysis [PDF]

, 2014
Whether physical activity increases or decreases the risk of atrial fibrillation (AF) remains controversial. We conducted a systematic review and meta-analysis to evaluate the relationship between AF and extent of physical activity.

Electrocardiographic patch devices and contemporary wireless cardiac monitoring. [PDF]

, 2015
Cardiac electrophysiologic derangements often coexist with disorders of the circulatory system. Capturing and diagnosing arrhythmias and conduction system disease may lead to a change in diagnosis, clinical management and patient outcomes.

Flutter atrial: uma revisão de literatura

Brazilian Journal of Health Review
O flutter atrial é uma arritmia cardíaca causada por um circuito de reentrada nos átrios, predominantemente no átrio direito, e está associado a condições como doenças cardíacas estruturais, hipertensão, DPOC e abuso de substâncias.

Modes of Initiation of Two Types of Atrial Reentry in a Patient with Typical Atrial Flutter: Isthmus-dependent Micro-reentry versus Macro-reentry

Journal of Arrhythmia, 2005
We studied the modes of initiation of two types of atria] reentrant tachycardias (i.e., microreentry isthmus tachycardia and counterclockwise atrial flutter) in a 39-year-old male with typical atrial flutter.

Digoxin for atrial fibrillation and atrial flutter: A systematic review with meta-analysis and trial sequential analysis of randomised clinical trials

PLoS ONE, 2018
Background During recent years, systematic reviews of observational studies have compared digoxin to no digoxin in patients with atrial fibrillation or atrial flutter, and the results of these reviews suggested that digoxin seems to increase the risk of ...

ArNet-ECG: Deep Learning for the Detection of Atrial Fibrillation from the Raw Electrocardiogram [PDF]

arXiv, 2022
Atrial fibrillation (AF) is the most prevalent heart arrhythmia. AF manifests on the electrocardiogram (ECG) though irregular beat-to-beat time interval variation, the absence of P-wave and the presence of fibrillatory waves (f-wave). We hypothesize that a deep learning (DL) approach trained on the raw ECG will enable robust detection of AF events and ...
