Quantitative ballistocardiography (Q-BCG) for measurement of cardiovascular dynamics.
In the seventies of the past century ballistocardiography had been thought to be obsolete in cardiology for impossibility of objective calibration. In the present work the quantitative ballistocardiography (Q-BCG) for measurement of systolic force (F) and minute cardiac force (MF) in sitting subject was described. The new principle of piezoelectric transducer enabled to register the force cause...
متن کاملSystem Dynamics Aproach For Quantitative Risk Allocaion
Allocation of construction risks between clients and their contractors has a significant impact on the total construction costs. This paper presents a system dynamics (SD)-based approach for quantitative risk allocation. Using the proposed SD based approach, all the factors affecting the risk allocation process are modeled. The contractor’s defensive strategies against the one-sided risk alloca...
متن کاملTheory and Developments in an Unobtrusive Cardiovascular System Representation: Ballistocardiography
Due to recent technological improvements, namely in the field of piezoelectric sensors, ballistocardiography - an almost forgotten physiological measurement - is now being object of a renewed scientific interest.Transcending the initial purposes of its development, ballistocardiography has revealed itself to be a useful informative signal about the cardiovascular system status, since it is a no...
متن کاملA new index for quantitative ballistocardiography: the velocity of body displacement.
Calculation of the velocity of body displacement and of the momentum of the body from 100 normal ballistic tracings shows that the values of the velocity of body displacement present a small scatter (mean value 68.3 + 13.9 mm. per second) and are independent of body weight and surface area. For uniformity of values and simplicity of calculation, which can be effected also on many abnormal traci...
متن کامل[New trends in ballistocardiography].
Balistocardiography is a method by which body vibrations caused by heart activity are registered. Evolution during the past fifty years to the present is described. Balistocardiography (BCG) represented by instruments of different natural frequencies and damping should bring information about cardiac output. This expectation was not fulfilled due to the unsuitable physical properties of apparat...
