Analysis of heart rate variability wave structure at diagnosis of arrhythmias of ischemic genesis

Presented here results of investigation of 971 patients (pts) with coronary artery disease and different clinical forms arrhythmias of ischemic genesis. Except standard cardiological methods, all pts investigated by high-resolution rhythmocardiography (RCG) and analysis of heart rate variability (HRV) wave structure. The exactitude of registration HRV, keeping it at computer memory there was 1000+3 Hz. Except research of autonomic sympathetic and parasympathetic heart rhythm regulation, also there was evaluated humoral-metabolic influences on the HRV. There was defined, that the majority of the heart arrhythmias may be registered on rhythmocardiogram and visually may be discerned. Also RCG has some advantages, which aren’t registering by other methods. There are advantages: the possibilities of autonomic arrhythmogenic background evaluation, discovery of their connection with sympathetic or parasympathetic tone, and also evaluation of hemodynamic significance and danger for life of the every arrhythmic episode. Also there were defined predictor of heavy arrhythmia - it is autonomic cardioneuropathy, significant HRV reduction and reactions absence of it in tests. High-resolution RCG is adequate and informative method in clinical arrhythmology.Представляются результаты обследования 971 больного с хронической ишемической болезнью сердца и различными клиническими формами кардиоаритмий. Помимо стандартных кардиологических методов всем пациентам проводилась ритмокардиография высокого разрешения (РКГ) с анализом волновой вариабельности сердечного ритма (ВСР). Точность регистрации электрокардиосигнала, хранение его в памяти компьютера были 1000+3 Гц. Оказалось, что большинство аритмий регистрируются на ритмокардиограмме (Ркг), визуально распознаются, могут быть анализированы с точностью в 1 миллисекунду, имеют преимущества, не регистрируемые другими методами - возможность оценки автономного (вегетативного) аритмогенного фона нарушений ритма, их зависимости от преобладания симпатического или парасимпатического отделов вегетативной системы, а также гемодинамического значения и жизнеопасности каждого эпизода аритмии. Выделен предиктор кардиоаритмии- синдром автономной кардионейропатии с предельно выраженным снижением ВСР и реакций ритма на стимулы в пробах. РКГ является адекватным и информативным методом диагностики в клинической аритмологии

Differitial diagnosis of sinoatrial blockade in rhythmocardiography

Researches had studied in arrhythmology during 5-8 years for evaluation of high-resolution rhythmocardiography (RCG) possibilities for sinoatrial blockade differential diagnosis. 362 patients (pts) (270 with dysfunction of sinus node-DSN- and 92 with sick sinus syndrome -SSS). The differential signs were defined between at functional sinus breaches and morphological SSS. They have different autonomic background, DSN has more safe wave HRV structure, and at the SSS was define syndrome autonomic cardioneuropathy with stabilization of the HRV and life-dangerous arrhythmias, for example –atrial fibrillation. RCG shows hemodynamic meaning of every arrhythmic episode, that is very important in treatment.Проводились исследования в аритмологии для оценки возможностей метода ритмокардиографии высокого разрешения (РКГ) для анализа вариабельности сердечного ритма в (ВСР) дифференциальной диагностике синоатриальной блокады. В течение 5-8 лет проводились РКГ-обследования 362 пациентов с дисфункцией синоатриального узла (ДФСУ) на фоне ишемической болезни сердца (ИБС). Из их числа выделены 92 случая с синдромом слабости синусового узла (СССУ). Найдены дифференцированные признаки между функциональными нарушениями (ДФСУ) и синоатриальной блокадой органического генеза, их автономного фона и гемодинамического значения аритмических эпизодов

Focus on high energy particles and atmospheric processes

The letters published in the ‘Focus issue on high energy particles and atmospheric processes’ serve to broaden the discussion about the influence of high energy particles on the atmosphere beyond their possible effects on clouds and climate. These letters link climate and meteorological processes with atmospheric electricity, atmospheric chemistry, high energy physics and aerosol science from the smallest molecular cluster ions through to liquid droplets. Progress in such a disparate and complex topic is very likely to benefit from continued interdisciplinary interactions between traditionally distinct science areas

High-resolution rhythmocardiography and diagnostic possibilities

Energetic particle influence on the Earth's atmosphere

This manuscript gives an up-to-date and comprehensive overview of the effects of energetic particle precipitation (EPP) onto the whole atmosphere, from the lower thermosphere/mesosphere through the stratosphere and troposphere, to the surface. The paper summarizes the different sources and energies of particles, principally galactic cosmic rays (GCRs), solar energetic particles (SEPs) and energetic electron precipitation (EEP). All the proposed mechanisms by which EPP can affect the atmosphere are discussed, including chemical changes in the upper atmosphere and lower thermosphere, chemistry-dynamics feedbacks, the global electric circuit and cloud formation. The role of energetic particles in Earth’s atmosphere is a multi-disciplinary problem that requires expertise from a range of scientific backgrounds. To assist with this synergy, summary tables are provided, which are intended to evaluate the level of current knowledge of the effects of energetic particles on processes in the entire atmosphere

Combination of the W boson polarization measurements in top quark decays using ATLAS and CMS data at root s=8 TeV

The combination of measurements of the W boson polarization in top quark decays performed by the ATLAS and CMS collaborations is presented. The measurements are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 8 TeV, and corresponding to an integrated luminosity of about 20 fb(-1)for each experiment. The measurements used events containing one lepton and having different jet multiplicities in the final state. The results are quoted as fractions of W bosons with longitudinal (F-0), left-handed (F-L), or right-handed (F-R) polarizations. The resulting combined measurements of the polarization fractions are F-0= 0.693 +/- 0.014 and F-L= 0.315 +/- 0.011. The fractionF(R)is calculated from the unitarity constraint to be F-R=-0.008 +/- 0.007. These results are in agreement with the standard model predictions at next-to-next-to-leading order in perturbative quantum chromodynamics and represent an improvement in precision of 25 (29)% for F-0(F-L) with respect to the most precise single measurement. A limit on anomalous right-handed vector (V-R), and left- and right-handed tensor (g(L), g(R)) tWb couplings is set while fixing all others to their standard model values. The allowed regions are [-0.11,0.16] for V-R, [-0.08,0.05] for g(L), and [-0.04,0.02] for g(R), at 95% confidence level. Limits on the corresponding Wilson coefficients are also derived.Peer reviewe
