WebTriphasic Waves with Sharp and Slow Wave Complexes (Slow Spike-Waves) One hundred randomly selected EEGs (67 patients) contain ing sharp and slow wave complexes (SSWC) were searched for TWs. Such TWs were further analysed for relative amplitudes of individual components and anterior-posterior or posterior-anterior delay. RESULTS Etiology WebAug 31, 2024 · Triphasic waves (TW) are included in the GPDs, and often described as GPDs with triphasic morphology [ 4, 26 ]. The prevalence of GPDs varied from 0.8 to 4.5% in critically ill patients.
