• ejection
  • Compared with controls (n = 24), subjects with high-output HF displayed eccentric left ventricular remodeling, greater natriuretic peptide activation, higher filling pressures, pulmonary hypertension, and increased cardiac output, despite similar ejection fraction. (semanticscholar.org)
  • Given the high mortality and increasing prevalence of these comorbidities in Western countries, high-output HF must be considered in the differential diagnosis of patients presenting with dyspnea, congestion, and a normal ejection fraction. (semanticscholar.org)
  • temporal frequency division preferably obtained from the thoracic impedance signal derived after temporal low-pass filtering and high-pass in order to identify the wave events B and X, which are used to determine the time ventricular ejection and dZ / dTmin for determining the stroke volume of the heart by conventional methods.

  • In our previous reports, we have confirmed that a thorax is nearly assumed as an electrical cylinder model when a pair of current injection spot-electrodes are placed far from the thorax like a placement of the forehead - left medial knee or the mastoid process - lower right abdomen, and that the changes in current distributions associated with cardiac blood ejection are roughly homogeneous around the medial line of the thorax.

  • impedance
  • Transthoracic electrical impedance (or admittance) cardiography is a simple technique for the non-invasive and continuous monitoring of stroke volume or cardiac output by detecting the electrical impedance of a thorax which is roughly assumed to be a two-compartment coaxial cylindrical model composed of the aorta and its surrounding thoracic tissues.
