Its application for solving clinical problems potentially related to cardiac arrhythmias is rapidly increasing. In the meantime, the method has found widespread use in the identification of patients at risk for cardiac death as well as in the assessment of therapeutic interventions. It was the purpose of this symposium to bring together an international group of authorities in order both to provide an overall view of the field and to discuss critically the value of clinical, epidemiological and research applications of long term ambulatory electrocardiography in the light of new concepts and recent advances. The first section of this volume discusses the methodology and the performance criteria of the equipment and analysis systems. In the second section, the potentials and problems encountered in the use of long-term ambulatory electrocardiography for solving clinical questions and for predicting the occurrence of clinically important arrhythmias are extensively dealt with. New applications such as continuous ST segment monitoring, blood pressure measurement and other physiologic parameters are also included. Prevalence variability and prognostic aspects of ventricular arrhythmias, both in normals and in patients with cardiac disease, are the subject of section 3. The last section provides a critical review of the use of the method for the evaluation of therapeutic interventions with drugs. The editors feel that this volume represents the 'state of the art' in this newly important area of clinical cardiology. J. Roelandt P.G. Hugenholtz ACKNOWLEDGEMENTS The contents of this volume represent the accumulated scientific information that emerged from the symposium on Holter Electrocardiography held in October 1981 at the Thoraxcentre of the Academic Hospital Dijkzigt and the Erasmus University in Rotterdam. Each of the speakers kindly consented to supply a manuscript of their presenta tion and we would like to express our gratitude to them. The symposium was sponsored by the European Society of Cardiology and financial support was provided by the Cardiolab Foundation. The organization required a great deal of work and of secretarial assistance. Mrs Marjolijn Sneep-de Korver handled this with great dedication and efficiency, for which we are most grateful. We also much appreciate Mr B.F. Commandeur's professional help with the production of this volume. J. Roelandt January 1982 P.G. Hugenholtz vii CONTENTS v Preface. Acknowledgements. VI SECTION 1.
