waveform

[′wāv‚fȯrm]
(physics)
The pictorial representation of the form or shape of a wave, obtained by plotting the displacement of the wave as a function of time, at a fixed point in space.

waveform

The shape of an audible or electronic signal. On an oscilloscope, analog waveforms show up as smooth curved lines that rise and fall (sine waves), while digital waveforms appear as square-shaped vertical and horizontal lines. See wavelength, sine wave and square wave.

Since 1988 thoracotomy became unnecessary and the pacing lead system was placed transvenously [5], monophasic waves were no longer satisfactory for the transvenous approach, and which benefited the development of biphasic waveforms in 1991.

The shock success rate--defined as eradication of ventricular fibrillation after the first shock and restoration of an organized rhythm marked by at least two QRS complexes within 5 seconds--was 69% in patients undergoing biphasic waveform defibrillation and 45% with monophasic.
Rolf Stutz, chairman and CEO of ZOLL added, "Beyond the growth in our existing products during the second quarter, our release of initial clinical trial results of our clinically advanced, patented Biphasic waveform technology was extremely well received by clinicians at the American College of Cardiology Convention in March.
