A simple ballistocardiographic system for a medical cardiovascular physiology course.
Ballistocardiography is an old, noninvasive technique used to record the movements of the body synchronous with the heartbeat due to left ventricular pump activity. Despite the fact that this technique to measure cardiac output has been superseded by more advanced and precise techniques, it is useful for teaching cardiac cycle physiology in an undergraduate practical course because of its nonin...
متن کاملBallistocardiographic study in severe anemia.
ANEMIA affects the heart by impairing the oxygen supply of the myocardium and by increasing the mechanical load on the heart through alterations in the circulatory dynamics. Irrespective of the cause of anemia, the cardiac and circulatory disturbances are identical as long as the anemia is severe. With the introduction of ballistocardiographic technics, a new tool became available for the study...
متن کاملمقایسه تغییرات برون‌ده قلبی در 2 روش بیهوشی با هالوتان و پروپوفول در بیماران تحت عمل ترمیم روتاتورکاف در وضعیت نشسته با روش غیرتهاجمی
Maintenance of cardiac output in normal range to assure tissues and vital organ perfusion is one of the most important tasks of anesthetists. Hemodynamic and cardiac indices(e.g. cardiac output) change due to either anesthetic drugs or changes in body position during various surgical operations and they have also been important and notable problems. The goal of the present study was...
متن کاملEffect of Physiological noise on Thoraco-Lumbar spinal cord fMRI in 3T Magnetic field
Introduction: Functional MRI methods have been used to study sensorimotor processing in the brain and the Spinal cord. However, these techniques confront unwanted contributions to the measured signal from physiological fluctuations. For the spinal cord imaging, most of the challenges are consequences of cardiac and respiratory movement artifacts that are considered as signifi...
