A comprehensive evaluation of 62 spirometers from 37 different sources was performed using a two-part protocol: calibrated syringe, and dynamic waveform testing. All testingwas done with ambient air. Calibrated syringe testing examined the ability of the spirometers to accurately measure the output of a 3 L calibrating syringe under varying conditions. The accuracy, FVC volume linearity, and st...

Background—Numerous criteria believed to define a positive response to cardiac resynchronization therapy have been used in the literature. No study has investigated agreement among these response criteria. We hypothesized that the agreement among the various response criteria would be poor. Methods and Results—A literature search was conducted with the keywords “cardiac resynchronization” and “...
