Surface ECG Signal Recording for the Implantable Subcutaneous String Defibrillator (ISSD) Detection Algorithm Performance Assessment

Recorded cutaneous ECG containing arrhythmia events are separately analysed by an expert Electrophysiologist and the ISSD detection algorithm, to allow assessment of the correct detection ...

Novel Methods for Arrhythmia Detection

Aims Approximately 20-25% of strokes are of cardioembolic origin, atrial fibrillation (AF) being a significant cause of cardioembolic strokes. AF is often symptomless and intermittent, mak...

Micra Atrial Tracking Using a Ventricular Accelerometer Study

The purpose of this study is to characterize performance of the MARVEL algorithm downloaded into the MicraTM TPS to provide atrial synchronous ventricular pacing in subjects with AV block.

Spontaneous Atrio Ventricular Conduction Preservation

In case of sinus node dysfunction, it is often necessary to choose the safer option provided by a DDD pacemaker even though the most appropriate mode of pacing is AAI mode. In addition to...

Prediction of Treatment Response at 6 Months by Combinatorial Analysis of Serum Biomarkers in Biotherapy Naive SpA

The main objective of this trial is to search for biomarkers associated with the success of adalimumab treatment in order to generate an algorithm to predict the response to this treatment...

Preferential conduction in arrhythmia ablation.

Characterisation of re-entrant circuit (or rotational activity) in vitro using the HL1-6 myocyte cell line.

Fibrillation is the most common arrhythmia observed in clinical practice. Understanding of the mechanisms underlying its initiation and maintenance remains incomplete. Functional re-entries are potent...

Does the comparison of median-to-ulnar nerve sensory conduction add an additional value in electrodiagnosis of carpal tunnel syndrome?

Distal sensory onset latency (DSOL), conduction velocity (SCV) and nerve action potential (SNAP) amplitudes are used in electrodiagnosis of carpal tunnel syndrome (CTS) beside motor conduction data. T...

QRS Detection Based on Improved Adaptive Threshold.

Cardiovascular disease is the first cause of death around the world. In accomplishing quick and accurate diagnosis, automatic electrocardiogram (ECG) analysis algorithm plays an important role, whose ...

Asymptomatic ventricular pre-excitation: what management?

The management of asymptomatic patients with ventricular pre-excitation diagnosed occasionally is controversial. In fact, the lack of clinical arrhythmias does not necessarily define a benign conditio...

Medical and Biotech [MESH] Definitions

One of the ANTI-ARRHYTHMIA AGENTS, it blocks SODIUM CHANNELS and slows conduction within the His-Purkinje system and myocardium.

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 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.

Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.

Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
