Opis

"Rate Adaptive Cardiac Pacing" provides a comprehensive overview of this most advanced form of stimulating the heart by means of cardiac pacemakers that vary the pacing rate according to the needs of the patients. The heart rate is controlled by one or several sensors that detect various parameters such as respiration, blood temperature, oxygen saturation, intracardiac pressure, QT interval, stroke volume andbody activity. Besides describing the clinical and functional characteristics of these various sensors, the book also gives a clear understanding of hemodynamic aspects and in particular, all clinical issues of importance such as indications for rate adaptive pacing and selection of the appropriate patients for rate adaptive pacemakers, with many ECG samples. The book also covers new concepts in rate adaptive pacing such as single lead atrial synchronous pacing and the combination of various sensors, which are among the most recent developments in the field. With contributions from the most wellknown experts in the field from allover the world, this book is the first publication to cover all the hemodynamic, clinical and technical aspects of rate adaptive cardiac pacing.
