The effect of right ventricular pacing on left ventricular relaxation was studied in 13 patients (age 62 +/- 3 years), with the atrial sensing ventricular pacing mode (VDD). A control group of similar age (64 +/- 4 years) consisted of 11 patients with atrial pacing (AAI). The timing of events was determined in both groups at similar R-R intervals (921 +/-(More)
An outbreak of severe hemorrhagic fever with renal syndrome (HFRS) occurred in 1988 in Pozarevac, Serbia, Yugoslavia. The disease was diagnosed in 4 children and 1 adult, and 1 of the children died. Rodents were captured from the same area and virus isolation attempted. A hantavirus, POZ-M1, was isolated from lung tissues of hantavirus antigen-positive Mus(More)
Acute and chronic threshold measurements were compared for three different electrodes: the Medtronic Target Tip model 4011, the Medtronic Ring Tip Model 6971 and the Siemens-Elema Carbon Tip Model 412S. The results of this study show that acute thresholds are lower with the Target Tip lead as compared to the other two. This finding applies to chronic(More)
A total of 46 patients with syncopal episodes after VVI pacemaker implantation were studied. Of these, 92% had one to three syncopal episodes and 8% more than three. All underwent a thorough clinical examination, which included chest X ray, echocardiogram, neurological exam, and the following protocol: 24-hour Holter monitoring, EEG, blood pressure (BP)(More)
Two biologically and genetically distinct hantaviruses were isolated from blood and urine specimens collected from four Yugoslavian patients with clinically severe hemorrhagic fever with renal syndrome (HFRS). Viral isolates from three patients, designated strains Belgrade 1-3, were distinct from Hantaan, Seoul, Puumala, and Prospect Hill viruses as(More)
OBJECTIVE We examined the prevalence of venous obstruction in 12 newborns and infants with permanent endovenous ventricular pacing, clinically, and by ultrasonographic assessment of hemodynamics (spontaneity, phasicity, velocity, and turbulence of flow) and morphologic parameters (compressibility, wall thickness, and thrombus presence). MATERIAL AND(More)
The early postoperative results of 44 surgically treated popliteal arterial injuries from the Yugoslav civil war are reported. Of these patients, 41 (93%) were males and three (7%) were females, average age was 28 (range 6-45) years. Twenty patients (45%) had gunshot wounds and 24 (55%) explosive wounds. Twelve (28%) suffered isolated vascular damage, while(More)
The aim of the paper is the presentation of the treatment of aneurysms of the extracranial carotid artery and review of literature. Aneurysms of extracranial carotid arteries (common carotid artery, external carotid artery and cervical part of the internal carotid artery) are very rate [1, 2]. In 1979 McCollum from the Baylor University (Houston, Texas)(More)
Endocardial pacing system implantation has been performed in 15 children of mean age 37 months (ranging from 1 day to 89 months). Endocardial lead fixation was performed by means of slowly resorbable suture (Dexon) to allow spontaneous lead migration as the child grows. During a mean follow-up period of 61 months (range 17-108 months), none of the patients(More)
Most centers worldwide use permanent endovenous cardiac electrostimulation in children requiring pacing whose body mass is over 10kg. The normal implantation route is via a subclavian vein puncture. In our Center, we have implanted permanent endovenous pacing systems for complete AV block in nine children with a mean body mass 7.4kg (range 2.45-10kg). The(More)
