Biphasic triphasic monophasic waveform

WebOct 25, 2009 · Biphasic and monophasic waveforms have been used for defibrillation. Older defibrillators deliver monophasic waveforms while the newer ones deliver biphasic waveform. Monophasic as the name implies, delivers current in only one direction. In monophasic damped sinusoidal waveform, the current returns to baseline gradually … WebJul 27, 2010 · The finding of an abnormal monophasic/biphasic CFA Doppler waveform is an 87% sensitive marker of proximal iliac disease. A monophasic waveform is 88% specific for iliac stenosis. Whilst CFA Doppler waveform morphology is a useful adjunct in detection of iliac disease normal triphasic CFA waveforms do not exclude iliac stenosis.
