In this paper, we propose a technique of artificial intelligence called adaptive neuro fuzzy inference system (ANFIS) for canceling maternal electrocardiogram (MECG) in fetal electrocardiogram extraction (FECG).This technique is used to estimate the MECG present in the abdominal signal of a pregnant woman. The FECG is then extracted by subtracting the estimated MECG from the abdominal signal. P...

This work describes a hybrid adaptive filtering technique, designed to optimize the removal of the electrocardiogram (ECG) from surface electromyography (sEMG) recordings. Using the adaptive noise cancellation technique (ANC), we minimize the error gradient based on combined Time-Frequency filtering enhancements. The validation on artificially prepared signals with a real data basis shows bette...

Supraventricular tachycardias (SVTs) are rhythm disturbances arising within the sinus node, the atrial tissue or the atrioventricular node. They are characterized by narrow QRS complex morphology on an electrocardiogram (ECG) and rapid heart rate. A correct diagnosis is essential for treatment and can sometimes be challenging as different rhythm disturbances may have a similar appearance on the...

OF the many attempts to analyze the nature of the electrocardiogram, the application of laws which define the spread of electrical currents in volume conductors have been most rewarding. However, problems peculiar to the living organism such as the influence of finite boundaries on the distribution of the action currents on the body surface, and the definition of a point of reference or zero po...

This report describes heart disease in a 32-year-old man with the syndrome of chronic progressive external ophthalmoplegia (CPEO). The surface electrocardiogram showed first degree AV block and left bundle-branch block and there was HV prolongation on the His bundle electrogram. Endomyocardial biopsy showed the changes of hypertrophy on light microscopy, and on electron microscopy there were in...

An automated monitoring system for home health care has been designed for an experimental house in Japan called the Welfare Techno House (WTH). Automated electrocardiogram (ECG) measurements can be taken while in bed, in the bathtub, and on the toilet, without the subject's awareness, and without using body surface electrodes. In order to evaluate this automated health monitoring system, overni...

The Osborn wave is a deflection immediately following the QRS complex of the surface ECG. It can be observed in hypothermic patients. A 51-year-old man was admitted to the emergency department of our hospital because of loss of consciousness with tonic-clonic seizures. The cranial computerized tomography (CT) showed intraparenchymal hematoma. After neurosurgical intervention, during hospitaliza...

A patient in whom Wenckebach phenomenon was observed to coexist in the three distal branches of the specialized ventricular conduction system, with an intermittent trifascicular block producing a second degree A-V block, is described. Surface electrocardiogram demonstrated the presence of this phenomenon in the right bundle branch (RBB) and the anterior division of the left bundle branch (LBB)....

Fetal electrocardiogram (fECG) monitoring is a technique for obtaining important information about the condition of the fetus during pregnancy and labour by measuring electrical signals generated by the fetal heart as measured from multi-channel potential recordings on the mother body surface. It is shown in this paper that the fetal ECG can be reconstructed by means of higher order statistical...

Fourteen patients with predominantly right sided dilated cardiomyopathy were studied, of whom five died suddenly. The condition is characterised by male preponderance, syncope, ventricular tachycardia, which typically has a left bundle branch block pattern on the surface electrocardiogram, and right heart failure. The diagnosis should be considered in patients presenting with otherwise unexplai...
