How does impedance cardiography work?
Technology Description. Impedance cardiography (ICG), also known as thoracic electrical bioimpedance (TEB), is a technology that converts changes in thoracic impedance to changes in volume over time. In this manner, it is used to track volumetric changes such as those occurring during the cardiac cycle.
What is ICG signal?
Impedance cardiography (ICG) is a safe, non-invasive method to measure a patient’s hemodynamic status. The ICG waveform is generated by thoracic electrical bioimpedance (TEB) technology, which measures the level of change in impedance in the thoracic fluid.
What is a BIOZ?
The Bio-Z test is a medical technology breakthrough that provides your cardiologist safe, noninvasive access to information about your heart’s ability to deliver blood to your body, how hard your heart is pumping, and the amount of fluid in your chest. It is much like an EKG using sensors placed on the neck and chest.
What is impedance in the heart?
Cardiac impedance is a measurement of the mechanical activation of the heart.
What is impedance in ECG?
Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and …
What is aortic impedance?
Aortic characteristic impedance (Zc) was calculated from the ratio of change in carotid pressure and aortic flow in early systole. Pulse wave velocity (PWV) was assessed from tonometry and body surface measurements.
What does ICG stand for medical?
Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, liver and gastric blood flow, and for ophthalmic angiography.
Is BIOZ a word?

What is meant by skin impedance?
Skin impedance is an important facet of bio-impedance and can be used to analyze the condition of the human body. Basically, skin impedance is the response of a specific skin region to an externally applied electrical current (or voltage) [11]. Therefore, the electrode is crucial for the detection of skin impedance.
What is called impedance?
Electrical impedance, measure of the total opposition that a circuit or a part of a circuit presents to electric current. Impedance includes both resistance and reactance (qq. The resistance component arises from collisions of the current-carrying charged particles with the internal structure of the conductor.
What does impedance mean in medical terms?
Medical Definition of impedance 1 : the apparent opposition in an electrical circuit to the flow of an alternating current that is analogous to the actual electrical resistance to a direct current and that is the ratio of effective electromotive force to the effective current.
