Biphasic Defibrillation vs. Monophasic Defibrillation â Gentle, yet effective, biphasic waveforms are now the standard of care. Biphasic defibrillation. This technology is known as monophasic waveform defibrillation. A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.Although not fully understood, this process depolarizes a large amount of the heart muscle, ending the dysrhythmia. Other types of defibrillators include standard defibrillators with a monitor, which can be monophasic or biphasic, as well as transvenous or implanted defibrillators. Unlike monophasic devices, biphasic defibrillators use a different waveform technology: either a biphasic truncated exponential (BTE) waveform or a rectilinear biphasic waveform (see Comparing waveforms). Implantable cardioverter-defibrillators (ICD) are defibrillators that are designed to help patients from inside their body. This technology is known as monophasic waveform defibrillation.
