Publication number: 20180325456Abstract: Medical devices and method for generating multi-time scale waveforms for display of sensor measurements are disclosed. Sensed or measured output signals from a sensor, such as a catheter, are processed to generate a first data set that uses a first time scale and a second data set that uses a second time scale. The generated data sets are then displayed on a display by juxtaposing the first data set with the second data set. In this manner, measurement data from the sensor can be shown in dual time scales that allow for faster and more efficient visual diagnostic assessments.Type: ApplicationFiled: May 9, 2018Publication date: November 15, 2018Inventors: Daniel Klebanov, Nicholas Herlambang, Ruslan R.
