UNLABELLED: The mechanisms of the protective effect of oligonucleotides (OGN) during pathological processes are poorlyunderstood. The goal of this work was to study the effect of OGN on arrhythmias induced by myocardial ischemia and reperfusion, and the HSP70 level in the heart. As a source of OGN was used the drug "Derinat" ("Technomedservis", Russia). In male Wistar rats were pre-treated the drug for 7 days (i/m, 7.5 mg/kg).The intensity of the arrhythmias was assessed by ECG during 10 min occlusion of the left coronary artery and subsequent 5 min of reperfusion...

INTRODUCTION: One-third of lone atrial fibrillation (AF) presents as familial disorder. Heterogeneity of both genetic background and clinical manifestations remains largely uncharacterized. We aimed to evaluate the clinical characteristics and especially the triggering factors of familial AF. METHODS AND RESULTS: Probands were screened from 84 consecutive lone AF patients seen in our tertiary hospital arrhythmia clinic. Those confirmed to have at least 1 first-degree relative with lone AF were included...

Preventive action of new antioxidant SkQ1 has been studied in rats on model of cardiac arrhythmia caused by epinephrine. The SkQ1 substance was given in dosages from 0.02 up to 20 moles/kg per os 2 weeks prior to experiment. Intravenous bolus introduction of epinephrine (10 or 6 mkg/kg in different experimental series) caused an immediate rise of arterial pressure in average by 19% and decrease in heart rate in average by 44%. The degree of changes of these parameters was approximately identical in all groups...

AIM: A detailed description of immune status abnormalities of adult patients with heart arrhythmia either idiopathic or in combination with primary heart disease such as chronic myocarditis and dilated cardiomyopathy (DCMP). MATERIAL AND METHODS: Eighty two consecutive patients aged 16-57 years admitted to the L.A. Myasnikov Institute of Clinical Cardiology (Moscow) for heart arrhythmia were studied. Among them 35 patients had idiopathic heart arrhythmia (IHA, group 1) with no evidence of any primary heart disease, while other 47 patients (group 2) had heart arrhythmia combined with primary heart disease (chronic myocarditis or DCMP)...

Aconitum napellus is an extremely dangerous plant that contains various toxic diterpenoid alkaloids, mainly aconitine primarily concentrated in the roots. We report a case of acute intoxication of a 21-year-old man admitted to our Emergency Department after the ingestion, in order to sleep, of three homemade Aconitum napellus capsules. Capsules were measured to contain 237 mg of root and 19 microg of aconitine. The patient experienced the first symptoms on wakening 5 hours later with generalized paresthesia, nausea, diarrhea, vertigo, thoracic pain dyspnea, and dyschromatopsia...

UNLABELLED: Patent foramen ovale (PFO) is a risk factor for transient ischemic attack (TIA) or ischemic stroke. In this study we investigated short and long-term safety and efficacy of percutaneous closure of PFO in secondary stroke prevention. METHODS AND RESULTS: We implanted PFO-closure devices in 8 patients (3 men and 5 women) after TIA or ischemic stroke (mean age 38 +/- 15.2). The implantation procedures were performed in general anesthesia, under transoesophageal echocardiography and fluoroscopy...

INTRODUCTION AND OBJECTIVE: The Central Nervous System (CNS) plays an essential role in the regulation of the cardiac function. There is strong evidence that many CNS lesions, mainly those of hemorrhagic origin, may induce repolarization abnormalities and enlargement of the QT interval (ECG changes) and several types of arrhythmias. In some cases these changes have been related to sudden death. The imbalance between the sympathetic and parasympathetic systems, favoring the former, seems to be the etiopathogenic factor...

A retrospective evaluation of 244 electrocardiograms obtained at rest at time of diagnosis from a population of 254 patients with intrathoracic sarcoidosis was carried out. Thirty-five (14%) were abnormal. Sinus tachycardia was present in 17 (7%), the rest encompassing various degrees of right-sided bundle branch, atrioventricular first degree block, ventricular extrasystolia and ST-depression. At follow-up after a median time of 27 years we found a significantly higher mortality risk in the group with ECG-changes compared to those without...

An Ambulatory ECG monitoring (AM) was carried out over a 24 hr. period on 90 healthy children divided into 3 age groups (lst week of life, 1 year of age and 5 years of age). There was a high number (about 50%) of unusable registrations because of detached electrodes, broken leads, and artifacts. The AM on children is characterised by: a) high values of the maximum frequencies (mean maximum absolute frequency 178 at birth, 164 at one year, 154 at 5 years); b) a great difference between the maximums and minimums; c) hourly variations related, above all, to feedings in the new-born babies and of a circadian type in the 5 years old children; d) almost constant marked sinus arrhythmias (80%); extremely rare extrasystolia (7...

In the investigations carried out the value of the noninvasive methods (routine-, three-minute-, 24-hour-, and load-ECG) for the diagnostics of latent ventricular disturbances of cardiac rhythm was controlled. 114 registrations of ventricular arrhythmias according to the Lown-classes with increasingly prolonged periods (1, 6, 12, and 24 hours) show that for the establishment of a ventricular extrasystolia of the classes IV and V a registrations lasting at least 24 hours is necessary. 1- and 3-minute-ECG are not suited for this...

In the ambulatory of an internal specialist a number of patients suffering from angina pectoris or hypertonia together with arrhythmic troubles received an initial treatment with beta-blockers over a period of 21 days. In cases in which arrhythmia persisted after this initial period the treatment was continued for another 21 days with the addition of Depasan retard in function of a second medicament. This combined treatment in form of an open study was extended to a total number of 50 patients presenting ventricular extrasystolia in 45 cases and in 5 cases absolute arrhythmia in addition to the main disease...

The authors describe their own method of right heart microcatheterization by means of transcutaneous introduction of an original unipolar microcatheter into the left subclavian vein. The method makes possible recording of th His bundle electrogram as well as of spike potentials of the sinus node and atrial conduction pathways. His bundle electrograms were recorded in 237 subjects, of whom 72 had ischaemic heart disease and 115 suffered from other cardiopathies, 50 persons with non-cardiac diseases constituted the control group...

Seventeen of 27 patients studied before and after surgical operations for basal meningioma frequently showed forms of cardial sinusal arythmia, sinusal tachycardia and ventricular extrasystolia. These pathological changes in cardiac rhythmics appeared and were aggravated during the postoperational period. Their possible pathophysiological mechanisms, due to the effect of the tumor and operative injury to the hypothalamo-diencephalic apparatus are discussed.

The study revealed the usefulness of the apexcardiogram in the assessment of the contractile state of left ventricle in cases of ventricular extrasystolia. The pre-ejection period/left ventricular ejection time (PEP/LVET) ratio and isovolumic contraction period (IVCP) are good parameters for demonstrating the postextrasystolic potentiation, the lack of which occurs in severe heart failure. PEP/LVET and IVCP are R-R-interval dependent in parasystolia. In the establishment of the postextrasystolic potentiation, the authors contribute an important role to the ventricular filling during the compensatory pause...

In 300 patients with extrasystolia and 36 patients with parasystolia a systematic search for reciprocal impulses was conducted with the aid of oesophageal ECG leads. Within 10-min periods, reciprocal impulses were detected in 13 patients (3.9 per cent). Reciprocal impulses occurred in extrasystolias of both functional and organic origin. Exercise contributes to the appearance of postextrasystolic reciprocal impulses. After intravenous injection of 10 mg Obsidan (propranolol hydrochloride) the phenomenon was less marked; in two patients, Obsidan oral medication (40 mg three times daily) led to the disappearance of reciprocal supraventricular paroxysmal tachycardia elicited by ventricular extrasystolia...
