Full Description
"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.
