Anterior-posterior impedance cardiography: a new approach to accurate, non-invasive monitoring of cardiac function.
The conventional impedance cardiogram is a record of pulsatile changes in the electrical impedance of the chest with each heartbeat. The signal seems intuitively related to cardiac stroke volume. However doubts persist about the validity of stroke volume measurements based on electrical impedance. This paper presents a new electrical axis for impedance cardiography that is perpendicular to the ...
متن کاملAccuracy of impedance cardiography for evaluating trends in cardiac output.
BACKGROUND Impedance cardiography (ICG) enables continuous, beat-by-beat, non-invasive, operator-independent, and inexpensive cardiac output (CO) monitoring. We compared CO values and variations obtained by ICG (Niccomo™, Medis) and oesophageal Doppler monitoring (ODM) (CardioQ™, Deltex Medical) in surgical patients. METHODS This prospective, observational, single-centre study included 32 sub...
متن کاملImpedance Cardiography for Cardiac Output Estimation
everal studies suggest the importance of cardiac power output calculation, which is derived from cardiac output (CO) and mean blood pressure, to predict the prognosis in heart failure patients not only in hospital but also in the outpatient setting.1–3 CO measured by the thermodilution method with a Swan-Ganz catheter placed in the pulmonary artery has become one of the most widely accepted and...
متن کاملNon-invasive estimate of cardiac output during exercise based on impedance cardiography and oxygen uptake in the elderly.
OBJECTIVE This study assessed the agreement between cardiac output (Q) measurements generated by two indirect methods and their applicability in 54 men and 77 women (aged 60-90). METHODS The subjects performed a cardiopulmonary test with incremental to maximal exercise on a cycle-ergometer. "Q" was estimated based on oxygen uptake and on impedance cardiography at 50% and 100% of the maximal w...
