T wave alternans (TWA) has been associated with ventricular arrhythmias. Hence, TWA detection can risk stratify patients with heart disease who may experience sudden death from ventricular arhythmias. However, accurate TWA detection is technically challenging due to the low microvolt TWA signal and the confounding effect of biological noise such as movement, myopotentials or respiration. In this paper, we propose nonnegative matrix factorization (NMF)-Adaptive spectral method to increase the robustness of TWA detection in ambulatory electrocardiograms (ECGs)...

Changes in cardiac rhythm are not the only determinants of blood pressure variations in man. They play a part in the variations of systolic and diastolic pressures, the relative importance of which depends on the degree of arhythmia present and on the depth of respiration which, in itself, causes the systolic and diastolic pressures to decrease during inspiration and increase during expiration. No degree of rate variation can be regarded as a type. The cases range from those in which respiration governs the change of pressures entirely through those where more or less complicated mixtures of heart rate and respiratory influences intermingle to those in which extreme cardiac variations alone determine the pressure changes...

The tumultuous auricular activity which follows faradization of the auricles of mammals and which has been variously described, could be distinctly seen to consist almost constantly in our experiments on dogs of true fibrillatory movements of the separate muscle fibers coëxisting with a rapid auricular tachycardia. During peripheral stimulation of the right vagus nerve the true fibrillation alone existed, the tachycardia being inhibited. A comparison of the electrocardiograms from dogs with this abnormal auricular activity with those from patients with the type of cardiac arhythmia which has been attributed to auricular fibrillation, and from patients with so called auricular flutter, indicates that the auricular activity in patients with either of these conditions differs somewhat from that usually seen in the faradized auricles of the dog in our experiments...

Borreliosis is a multisystemic disease transmitted by ticks. Its diagnosis still remains a challenge because of the varied clinical picture and of difficulties in detection of the etiological agent (Borrelia burgdorferi). We report a case of a 53-years-old woman admitted to the Clinic of Cardiology due to life-threatening arhythmias with simultaneous deficits in concentration and memory. A suspicion of borreliosis was driven from the presence of cardiac symptoms as well as of psychiatric and from the case histories of a tick bite...

It has been shown that impaired cardiac autonomic activity is closely related with lethal arhythmias. Heart rate variability (HRV), analysis of beat-to-beat variations, is an important and widely used non-invasive method to assess autonomic function. Impaired cardiac autonomic activity and altered sympathovagal balance were previously documented in patients with hypothyroidism. However, the effect of subclinical hypothyroidism (SH) on autonomic function has not been studied yet. We aimed to investigate the effect of SH on sympathovagal balance using the HRV method...

Paroxysmal atrial fibrillation is one of the most common disorders of cardiac rhythm. It is often a step toward permanent arhythmia, specially if associated with cardiac disease. The management objectives of intermittent arhythmia may be different, as maintenance of sinus rhythm. However, risks of stroke and thrombo-embolism are similar to those for sustained atrial fibrillation and must be carefully assessed. In this article we review the epidemiology, pathophysiology, clinical aspects and current guidelines for treatment and management of paroxysmal atrial fibrillation...

The purpose of this study was to evaluate the sedative-anaesthetic effects of a combination of medetomidine (M, 50 microg per pigeon), butorphanol (B, 50 microg per pigeon) and ketamine (K, 25 mg per pigeon) in domestic pigeons. Eight domestic pigeons (four male and four female, 8-15 months old) were used. The combination of Medetomidine and butorphanol injectable solutions were used to produce sedation. Ten minutes after M + B administration, K was injected. The anaesthetic effects of the drugs were reversed by administration of Atipamazole (AT) at 60 min after K administration...

BACKGROUND: The effects of sotalol on the 24-hour profile of the QT interval relative to that of the heart rate (HR) may be helpful in determining the time course of the drug's action in controlling cardiac arhythmias. This has not been previously determined. Thus, the objective of the current study was to evaluate the influence of the drug on the circadian rhythmicity of HR and QT intervals from Holter recordings in ambulatory patients. Reverse-use dependency (RUD) of sotalol was also studied noninvasively from Holter recordings...

We isolated mutants affected in the circadian expression of the psbAI gene in Synechococcus sp. strain PCC 7942 using a strategy that tags the genomic locus responsible for the mutant phenotype. The search identified one short period (22 h) mutant (M2) and two low amplitude mutants, one of which showed apparent arhythmia (M11) and one that was still clearly rhythmic (M16). We characterized the disrupted locus of the low amplitude but still rhythmic mutant (M16) as the rpoD2 gene, a member of a gene family that encodes sigma70-like transcription factors in Synechococcus...

The detailed study of a patient who suffered from a severe amelodia without arhythmia as a consequence of bilateral temporal lobe damage revealed that the processing of melodic information is at least partially separable from the processing of rhythmic information. This dissociation was replicated across different sets of material, was supported by the presence of a reversed association, and was maintained in conditions that promote integration in the normal brain. These results argue against the view that melody and rhythm are treated as a unified dimension throughout processing...

Lyme disease is an infectious, multisystem disease involving the skin, heart, joints, and nervous system. With its ability to assess cardiac anatomy, chamber sizes and myocardial and valvular function, echocardiography is a powerful noninvasive tool to investigate possible cardiac involvement in this disorder. We studied by echocardiography 15 patients, (6 women and 9 men, mean age 28.5 years, range 17 to 42) with clinical and electrocardiographic changes compatible with acute myocarditis or myopericarditis...

RU486 (mifepristone) followed by a prostaglandin (PG) analogue has been marketed in France since April 1990 as a medical alternative to surgery for early pregnancy termination. By law, the drug is used only in the centres approved for voluntary pregnancy termination, and its distribution is strictly controlled. Before being marketed, it was distributed to more than 20,000 women, as part of a training programme for the prescribers. Analysis confirmed an efficacy rate of 95.3%. Failures included incomplete ovular expulsion (2...
