To estimate the prevalence and incidence of atrial fibrillation in the entire population of Hungary. Analysis of the National Health Insurance Fund Administration database between 2007 and 2009 considering data from 2002. We assumed that patients with atrial fibrillation would turn to health care providers at least once either as outpatients or inpatients in a 5-year period. The National Health Insurance Patient Registry was used to assess the true number of patient visits. The prevalence of atrial fibrillation in Hungary is between 2.37-2.67%. Each year, only about half of these patients seek medical advice. Our survey seems to be the first epidemiological study that aims at estimating the prevalence of atrial fibrillation in the total population of our country. Using a time frame of five to seven years, the prevalence of atrial fibrillation in the total population is significantly higher than it was estimated earlier. However, by using a mathematical model, an even higher prevalence rate of atrial fibrillation (2.95%) was calculated for the total population of Hungary.

A Gerecse földtani térképezése során a Magyar Földtani és Geofizikai Intézet geológusai új, vagy régen feledésbe merült és részletesen soha nem dokumentált pannóniai feltárásokat azonosítottak a hegység északi előterében, az onnan dél felé felnyúló völgyekben, és a hegység belsejében is. Az ezekből begyűjtött puhatestű fauna (kiegészítve a már korábban ismert tatai puhatestű faunával és régebbi gyűjteményi anyagokkal) és a feltárásokban megfigyelhető szedimentológiai jellemzők alapján a pannóniai rétegsor itt is, mint az egész Dunántúli-középhegység északnyugati peremén, egyetlen transzgresszív-regresszív ciklusból áll. A ciklus transzgresszív szárnyát a tatai téglagyári feltárásokban a vékony transzgresszív bázisrétegre települő Száki Formáció kékesszürke agyagja és az abban megőrződött mély szublitorális fauna, míg a Gerecse központi részén, a tardosi Vályus-kút környékén, 375 méter tengerszint feletti magasságban a lignites agyaggal kezdődő rétegsor fedőjében települő, szintén mé...

Sedimentary successions exposed at basin margins as a result of late-stage inversion, uplift and erosion usually represent only a limited portion of the entire basin fill; thus, they are highly incomplete records of basin evolution. Small satellite basins, however, might have the potential of recording more complete histories. The late Miocene sedimentary history of the Șimleu Basin, a northeastern satellite of the vast Pannonian Basin, was investigated through the study of large outcrops and correlative well-logs. A full transgressive-regressive cycle is reconstructed, which formed within a ca. 1 million-year time frame (10.6-9.6 Ma). The transgressive phase is represented by coarse-grained deltas overlain by deep-water lacustrine marls. Onset of the regressive phase is indicated by sandy turbidite lobes and channels, followed by slope shales, and topped by stacked deltaic lobes and fluvial deposits. The deep-to shallow-water sedimentary facies are similar to those deposited in the...

The Pannonian (Late Miocene – Early Pliocene) Tihany Member (formerly Tihany Formation) was deposited in the littoral zone of Lake Pannon and in various deltaic environments. The embedded fossil mollusc fauna faithfully reflects the patchy environmental conditions, and encompasses a wide spectrum of ecological groups, from brackish littoral through freshwater to terrestrial molluscs. This paper gives a fairly complete illustration of the mollusc fauna of the Tihany Member in the Balaton region, based on the palaeontological investigation of two surface outcrops. The first outcrop is a 40 m highsection cut into the Papvasar Hill near Balatonfűzfő. Its mollusc fauna is outstandingly rich with 95 species. The lower part of the outcrop yielded some species that are characteristic of the sublittoral zone of Lake Pannon (Congeria praerhomboidea STEVANOVIC, Lymnocardium  majeri (HORNES)). Mass occurrence of littoral brackish molluscs, such as Melanopsis, Viviparus,  Theodoxus,  Lymnocardiu...

As the almost 200-year palaeontological research revealed, the geographical distribution of various fossil mollusk faunas in deposits of the late Neogene Lake Pannon displays a regular pattern. The lake basin was filled by lateral accretion of sediments, resulting in condensed sedimentary successions in the distal parts of the basin and successively younger shallow-water deposits from the margins towards the basin center. Exposed intra-basin basement highs, however, broke this strict pattern when they acted as sediment sources during the lake’s lifetime. The Mecsek Mts in southern Hungary was such an island in Lake Pannon during the early late Miocene. Deposition of the 200 m thick Sarmatian–Pannonian sedimentary succession in Pécs-Danitzpuszta at the foot of the Mecsek Mts was thus controlled by local tectonic and sedimentary processes, resulting in a unique succession of facies and mollusk faunas. A typical, restricted marine Sarmatian fauna is followed by a distinct freshwater or...
