Validation of a Smartphone-based Recorder for Detection of Cardiac Arrhythmias

2019-07-01 05:25:17 | BioPortfolio

Summary

The investigators will evaluate the diagnostic yield of the new AliveCor device versus a 12 lead ECG when used simultaneously to detect cardiac arrhythmia

Description

The investigators are planning to record 250 pre-defined abnormal ECGs (50 each of atrial fibrillation, atrial flutter, pre-excitation, ventricular tachycardia, , supraventricular tachycardia) and 150 control ECGs (100 sinus rhythm, 50 sinus tachycardia) using both the AliveCor Smartphone device and a 12-lead ECG. All 400 ECGs will then be read by 3 blinded reporters - a Consultant Electrophysiologist, a Consultant General Cardiologist and a General Practitioner. The output of the AliveCor automatic detection algorithm will also be recorded as a fourth reporter. The screening characteristics of all 4 reporters using the AliveCor device vs the definitive 12 lead ECG will be analysed and compared.

Increasing Mortality from Cardiac Arrhythmia in Germany?

The 'Deutscher Herzbericht 2016' [German Heart Report] reported a strongly increasing mortality rate from cardiac arrhythmia in Germany from 1990 to 2014. The increase was higher in women than in men ...

Management of arrhythmia recurrence in patients with pulmonary vein stenosis following atrial fibrillation ablation.

Arrhythmia recurrence is a common clinical problem in patients with pulmonary vein stenosis (PVS) following catheter ablation of atrial fibrillation. The study sought to analyse the management of arrh...

Emerging biomarkers for cardiac arrhythmias.

Cardiac arrhythmias are associated with substantial morbidity and mortality. Recent advances in the pathophysiological understanding of cardiac arrhythmia indicate that inflammation, fibrosis, and eve...

Fundamentals of Cardiac Mapping.

To characterize cardiac activity and arrhythmias, electrophysiologists can record the electrical activity of the heart in relation to its anatomy through a process called cardiac mapping (electroanato...

Surgical treatment of cardiac fibroma in a child with left ventricular noncompaction.

Surgical treatment of cardiac fibroma is rare in patients with left ventricular noncompaction (LVNC). Although several case reports regarding cardiac fibroma have been published, resection in a patien...

Medical and Biotech [MESH] Definitions

Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.

A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.

Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.

A potent anti-arrhythmia agent, effective in a wide range of ventricular and atrial arrhythmias and tachycardias. Paradoxically, however, in myocardial infarct patients with either symptomatic or asymptomatic arrhythmia, flecainide exacerbates the arrhythmia and is not recommended for use in these patients.

A type of cardiac arrhythmia with premature contractions of the HEART VENTRICLES. It is characterized by the premature QRS complex on ECG that is of abnormal shape and great duration (generally >129 msec). It is the most common form of all cardiac arrhythmias. Premature ventricular complexes have no clinical significance except in concurrence with heart diseases.
