[Resuscitations in the hospital: reporting using the Utstein-style form and a study of 183 patients in the St. Radboud University Medical Center, Nijmegen, the Netherlands, between 1997-2000].

Objective: To evaluate the completion of the Utstein-style forms after cardiopulmonary resuscitation (CPR) in the St Radboud University Medical Center, Nijmegen (UMCN), the Netherlands, and to assess the outcomes of the CPR attempts.

Design: Retrospective, descriptive.

Method: All Utstein-style forms used in the UMCN during the period 1 January 1997-31 December 2000 were examined.

Aspirin plus coumarin versus aspirin alone in the prevention of reocclusion after fibrinolysis for acute myocardial infarction: results of the Antithrombotics in the Prevention of Reocclusion In Coronary Thrombolysis (APRICOT)-2 Trial.

Background: Despite the use of aspirin, reocclusion of the infarct-related artery occurs in approximately 30% of patients within the first year after successful fibrinolysis, with impaired clinical outcome. This study sought to assess the impact of a prolonged anticoagulation regimen as adjunctive to aspirin in the prevention of reocclusion and recurrent ischemic events after fibrinolysis for ST-elevation myocardial infarction.

Methods And Results: At coronary angiography <48 hours after fibrinolytic therapy, 308 patients receiving aspirin and intravenous heparin had a patent infarct-related artery (Thrombolysis In Myocardial Infarction [TIMI] grade 3 flow).

Geometrical aspects of the interindividual variability of multilead ECG recordings.

The electrocardiogram (ECG) as measured from healthy subjects shows a considerable interindividual variability. This variability is caused by geometrical as well as by physiological factors. In this study, the relative contribution of the geometrical factors is estimated.

Factors influencing immediate and long-term outcome of electrical cardioversion of persistent atrial fibrillation and flutter.

Background: To investigate which factors influence the immediate and long-term outcome of elective electrical cardioversion for persistent (>48h) atrial fibrillation or flutter.

Methods: In 255 patients, 435 electrical cardioversions were performed. Relevant clinical, electrocardiographic and echocardiographic factors were registered at each cardioversion.

Geometrical factors affecting the interindividual variability of the ECG and the VCG.

Various measures for quantifying the interindividual variability of the electrocardiogram and the vectorcardiogram in healthy subjects are presented. An analysis of factors that may cause this variability is performed, in particular of the geometrical factors of body size, heart size, heart position, and orientation. The results indicate that the variations in the magnitude of the electrocardiogram as observed through leads placed on the anterior thorax are dominated by the solid angle at which the outline of ventricular mass is seen from points on the thorax.
