Detection of left ventricular systolic dysfunction using a newly developed, laptop based, impedance cardiographic index
Authors: Yoseph Rozenman , Renee Rotzak , Robert P Patterson Results: A GGI cutoff of 10 was 89% sensitive and 96% specific for the detection of LVSD, confirming the excellent results of the training set. Positive and negative predictive values were 78% and 98% respectively. False positives and false negatives of GGI as a predictor […]

Overview: Thermodilution using a pulmonary artery catheter is considered the gold standard in measuring cardiac output. However. Drawbacks associated with the technique have prompted clinicians to seek less invasive options. But these alternatives have their own limitations. We examine the evidence on four devices that measure cardiac output using. Summary: All six studies found a […]
