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. waveformThe 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.waveform
wave·form (wāv'fōrm), The form of a pressure or sound wave, electric stimulus, or pulse; for example, an arterial pressure or displacement wave; or of a sound or pacemaker pulse as demonstrated on an oscilloscope.wave·form (wāv'fōrm) The form of a pulse (e.g., an arterial pressure or displacement wave), or of the pacemaker pulse as demonstrated on the oscilloscope under a specified load. waveformThe shape or the representation of a signal, e.g., in cardiology, the shape of the electrical shock used in cardioversion or defibrillation.biphasic waveformA waveform used by some defibrillators that discharges energy in two phases (first positive, then negative). The shock applied by a biphasic defibrillator uses 30-40% less peak current at the same applied energy level than a monophasic defibrillator and is both less injurious to the heart and more likely to terminate ventricular fibrillation. damped sinusoidal waveformA defibrillation waveform that rises sharply to a peak voltage and then returns gradually to zero.monophasic waveformA waveform used by some defibrillators that delivers a single shock of positive energy to the myocardium. truncated exponential waveformA defibrillation waveform that rises sharply to a peak voltage and then is abruptly cut off and returns to zero.FinancialSeeSine Wavewaveform
