The book describes Dr. Sevelius' long career as medical scientist, pursuing specifically what can be learned from a radiocardiogram (RCG), the recording through the skin of the heart flow, the cardiac output (CO), the most fundamental of all body functions. The RCG has been slow in acceptance in clinical medicine. One worry has been the radiation. The radiation is approximately one-third that of a chest x-ray and should be of minor concern with proper education. Another difficulty is how to interpret the results. Other techniques for CO measurements have had similar problems, not because the techniques were wrong but because the interpretation was based on wrong premises with too wide a standard deviation for proper diagnosis in clinical work. Dr. Sevelius introduces two new assessments: hemodynamic and metabolic. With these interpretations the heart as a pump is first judged according to the size of simultaneously measured blood volume it has to pump and second, separately, as to how large a body the heart has to supply with oxygen. The hemodynamic evaluation of the heart flow is found to be a good predictor to a within six-month pending heart attack. This would make the RCG an exceptionally simple and useful tool for diagnosis in clinical medicine. This book collects Dr. Sevelius' work in digital format to make it easily available. It is Dr. Sevelius' hope that his work will inspire some young scientists to follow up his work because of its wide application in modern medicine.

About the author (2011)

After graduation from Karolinska Institute of Medicine in Stockholm, Sweden, Dr. Sevelius declared interest for blood flow marking the blood with an isotope and measuring regional blood flow through the skin. He was recognized as having research ideas worth pursuing. He was sent to University of Oklahoma Medical School in Oklahoma City to explore what he could do. He identified coronary blood flow from the radiocardiogram. The Federal Aviation Agency sponsored Dr. Sevelius to study the quantitative assessment of fatigue and aging as possible objective indicators for heart attacks in pilots.Dr. Sevelius also joined a group of 13 scientists to study the psychosomatic relationship of life events with heart attacks, a study sponsored by the National Institute of Health.Dr. Sevelius followed his academic work with appointment as Medical Director, first for the National Aeronautic and Space Agency (NASA), and later for the Lockheed Missile and Space Corporation from which he eventually retired after 20 years. As Medical Director he initiated employee heath education. See "Add Years to Your Life and Life to Your Years."In retirement, Dr. Sevelius turned to Anthropology for a possible generic explanation to wars among nations. See "The Nine Pillars of History.
