WebFeb 16, 2024 · Arteries of the extremities show a triphasic pattern in the pulsed Doppler spectrum. The triphasic pattern has a first positive phase related with the systole of the left ventricle, a second negative phase related with the closure of the aortic valve, and a third positive phase produced by the elasticity of the arterial walls. WebMonophasic TMS Pulses: Monophasic pulse shapes (often referred to as ‘single pulse’) are predominantly used for testing the integrity of the cortico-spinal pathway, assessing interhemispheric inhibition and evaluating the excitability of corticocortical connections.
