Arrhythmias are a form of heart disease involving irregular heartbeats. Premature ventricular contractions (PVCs) are a type of arrhythmia that may indicate ventricular tachycardia (VT), a potentially life-threatening condition. A stand-alone embedded system has been developed to facilitate real-time arrhythmia detection, performing electrocardiogram (ECG) signal processing and alerting the pat...

• A new ECG arrhythmia classification method combining recurrence plot (RP) and deep learning in two stages is proposed. 1D signals were converted into 2D images using the RP tool to expose features for CNN classify. We applied since leverages spatial information, therefore well suited image classification. To archive better results, we took 2-second segments, then a two-stage R-peak detection....

Background: Idiopathic right ventricular arrhythmias (IRVA) are responsive to medical and ablative treatment and have a benign prognosis. Arrhythmias caused by right ventricular dysplasia (ARVD) are refractory to treatment and may cause sudden death. It is difficult to distinguish between these two types of arrhythmia. Objective: To differentiate patients with IRVA and ARVD by a conventional el...

BACKGROUND Cardiac involvement in sarcoidosis is often silent and may lead to sudden death. This study was designed to assess the value of programmed electric stimulation of the ventricle (PES) for risk stratification in patients with sarcoidosis and evidence of preclinical cardiac involvement on imaging studies. METHODS AND RESULTS Patients with biopsy-proven systemic sarcoidosis but without...
