This paper presents a development of a handheld device for single-channel ambulatory ECG measurements. Our ECG device is designed for easy-to-use. ECG signal will be recorded for 1 minute by placing both thumbs on two dry electrodes and we have used this device to collect ECG signals from 50 volunteers. An ECG database is created from the collected ECG signals with self-annotated locations of QRS...
Ischemic Heart Disease (IHD) and stroke are statistically the leading causes of death world-wide. Both diseases deal with various types of cardiac arrhythmias, e.g. premature ventricular contractions (PVCs), ventricular and supra-ventricular tachycardia, atrial fibrillation. For monitoring and detecting such an irregular heart rhythm accurately, we are now developing a very cost-effective ECG monitor,...
Premature Ventricular Contraction (PVC) is one of the most common cardiac arrhythmias. PVC can occur in healthy people, but for those with frequent occurrence of PVCs, this can often be linked to pathological disorders of the heart. PVC detection allows the physician to diagnose heart disease accurately and also helps cardiac patients to be monitored effectively. This paper presents a novel algorithm...
This paper proposes a real-time algorithm of Premature Ventricular Contraction (PVC) detection based on a low computational method. This algorithm considers three time-domain features which are RR-interval, QRS-width and QRS-pattern. Simple decision rules are used in the classifier process which is suitable for embedded applications. The algorithm was tested with 26 ECG records from MIT-BIH Arrhythmia...
Holter recording of electrocardiographic signal (ECG) is usually disturbed by noise added to measured useful signal due to e. g. worse contact skin-electrode, body movements, etc. Our general goal is to find at least some piece of information from ECG (in our case - positions of QRS complexes) in corrupted signal, on which common preprocessing methods fail. The main purpose of the article is description...
