Klappentext zu „Investigative Electrocardiography in Epidemiological Studies and Clinical Trials “
This book on investigative electrocardiography is addressed to investigators who are using electrocardiology as a research tool in epidemiological or clinical research or in investigations on possible adverse responses of new pharmacological agents. The primary emphasis of the book is on prognostic implications of ECG abnormalities in the conditions covered, including the prevalence and incidence of ECG abnormalities in contrasting populations. We excluded from our book cardiac disorders with a relatively low population pre- lence that otherwise may be of great clinical interest. We also decided to exclude acute myocardial infarction because we had only limited resources available on this topic from our population studies and from those clinical trials in which we have personally p- ticipated in the classi? cation of trial endpoints within the framework of an ECG research center. Clinical trials are a relatively new area of electrocardiology. However, electrocard- graphy has become a most valuable research tool in clinical trials and in investigations on morbidity and mortality risk associated with various clinical and subclinical con- tions. It has also become a crucial research tool in investigating adverse cardiac events associated with administration of new drugs. Evaluation of QT prolongation plays a central role in these investigations. As a possible marker of malignant arrhythmias, it is used by regulating agencies in their decision process for approval of new pharmacolo- cal agents.

Autoren-Porträt von Pentti Rautaharju, Farida Rautaharju
The authors have closely collaborated for over a quarter of a Century in operating an academic ECG Center that has been in charge of ECG analysis of all major national health surveys conducted by the US National Center for Health Statistics, a series of large cardiovascular observational studies and clinical trials conducted by the US National Heart, Lung, and Blood Institute and several large clinical trials sponsored by pharmaceutical industry.

Pressezitat
From the reviews: "This book reviews common ECG abnormalities in various populations and focuses on the prevalence and incidence of these abnormalities as well as the prognostic implications of the findings. It uniquely provides an extensive series of tables listing normal standard of ECG intervals, amplitudes, and vectors in various populations ... . Investigators using electrocardiography as a research tool are the intended audience ... . This is a thorough book that will be useful to its targeted audience." (Marc N. Saad, Doody's Review Service, August, 2008)
