BMC Pediatrics, 2020 Background Atrial flutter (AFL) is a supraventricular tachyarrhythmia. In the ECG tracing, it is marked by a fast, irregular atrial activity of 280–500 beats per minute.

Classification of Human Ventricular Arrhythmia in High Dimensional Representation Spaces [PDF]
arXiv, 2013 We studied classification of human ECGs labelled as normal sinus rhythm, ventricular fibrillation and ventricular tachycardia by means of support vector machines in different representation spaces, using different observation lengths. ECG waveform segments of duration 0.5-4 s, their Fourier magnitude spectra, and lower dimensional projections of ...

New England Journal of Medicine, 1992 BACKGROUND Atrioventricular nodal reentrant tachycardia (AVNRT), the most common form of supraventricular tachycardia, results from conduction through a reentrant circuit comprising fast and slow atrioventricular nodal pathways.

Ventricular Tachycardia in the Absence of Structural Heart Disease [PDF]
, 2005 In up to 10% of patients who present with ventricular tachycardia (VT), obvious structural heart disease is not identified. In such patients, causes of ventricular arrhythmia include right ventricular outflow tract (RVOT) VT, extrasystoles, idiopathic ...

Postural Tachycardia Syndrome (POTS)
Circulation, 2013 Patient O.T. is a 26-year-old white woman who works in the music industry. She was diagnosed with pneumonia and treated with inhalers. Shortly afterward, she developed spells of tachycardia.

Learning disentangled representation from 12-lead electrograms: application in localizing the origin of Ventricular Tachycardia [PDF]
arXiv, 2018 The increasing availability of electrocardiogram (ECG) data has motivated the use of data-driven models for automating various clinical tasks based on ECG data. The development of subject-specific models are limited by the cost and difficulty of obtaining sufficient training data for each individual.

A young female patient with recurrent paroxysms of inappropriate sinus tachycardia
Journal of Family Medicine and Primary Care, 2019 Tachycardia is one of the most common presentations in medical practice. In most cases, it could be attributed to emotional problems, anemia, or thyroid disorders.

Characterization of blood pressure and heart rate oscillations of POTS patients via uniform phase empirical mode decomposition [PDF]
arXiv, 2019 Objective: Postural Orthostatic Tachycardia Syndrome (POTS) is associated with the onset of tachycardia upon postural change. The current diagnosis involves the measurement of heart rate (HR) and blood pressure (BP) during head-up tilt (HUT) or active standing test.

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.

Clinical Pharmacology &Therapeutics, EarlyView.Adverse drug reactions (ADRs) are a common cause of morbidity and mortality in hospitalized patients. Identification of ADRs in clinical practice, surveillance and research is essential to prevent further harm. The aim of this study was to assess the likelihood of drugs contributing to clinically important inpatient adverse events, in order to provide ...
