Electronic Fetal Heart Rate (FHR) monitoring is recommended to assess fetal well-being during labour in high risk pregnancies. This Cardiotocograph (CTG) relies on the ultrasound technology with limitation of signal loss 15% 40% cases [1]. In earlier versions these CTG monitors, heart tracings were generally reasonable quality many artefacts and some degree occasional large noise. Subsequent mo...

Heart disease is the leading cause of mortality worldwide, and it utmost importance that clinicians researchers understand dynamics heart. As an electrical measure heart’s activity, electrocardiogram, or ECG, gold standard for recording cardiac state, whether monitoring structure traces make up ECG indicating key metrics such as heart rate variability. Long-term often required to identif...

In-vivo monitoring of patient’s cardiac mechanics via seismocardiogram was recently introduced (demonstrated). Usually, seismocardiogram is recorded using accelerometers placed on patient’s sternum. This study present the ability of a PVDF piezo film transducer to record the mechanical activity of the heart (seismocardiogram and heart sounds) and also of the respiration-related, thorax motion. ...

Elevated resting heart rate is associated with greater risk of cardiovascular disease and mortality. In a 2-stage meta-analysis of genome-wide association studies in up to 8 , 7 individuals, we identified 4 new loci associated with heart rate and confirmed associations with all 7 previously established loci. Experimental downregulation of gene expression in Drosophila melanogaster and Danio rer...

Fetal heart rate and its beat-to-beat variability are two important indications about the health and condition of the fetus. The observed maternal electrocardiogram (ECG) signal consists of mother heart signal and fetal heart signal and is often very noisy. In this paper, we propose a multivariate singular spectrum analysis (MSSA) for extracting and separating the mother heart signal, the fetal...

Phonocardiography is a widely used method of listening to the heart sounds and indicating the presence of cardiac abnormalities. Each heart cycle consists of two major sounds - S1 and S2 - that can be used to determine the heart rate. The conventional method of acoustic signal acquisition involves placing the sound sensor at the chest where this sound is most audible. Presented is a novel algor...

ECG reports the electrical variations that arise in the heart. Any change in the normal ECG signal can cause cardiac problems. ECG signal involves different waves that are P, Q, R, S and T as shown in the fig. 1. These waves collectively constitute cardiac cycle. Doctors use this graph to measure the heart rate of a person and in case of any discrepancy or change in normal pattern, they take th...

Disorders in the functions of heart cause diseases or arrhythmias cardiovascular system. Diagnosis cardiac is realized utilizing Electrocardiogram which an electrophysiological signal. In this study, a three-class, K-means clustering-based arrhythmia detection method, distinguishing type Right Bundle Branch Block and Left from normal heart-beats, proposed. Data MIT-BIH Arrhythmia Database were ...
