Triphasic t wave
WebFeb 1, 2024 · Triphasic waves are abnormal electroencephalogram (EEG) waveforms seen in association with multiple clinical conditions, including encephalopathy and structural brain lesions, among others. They are nonspecific, high amplitude sharp/sharply contoured waves with three distinctive phases. WebAug 21, 2024 · A T wave which is inscribed on either side of baseline is called biphasic T wave. A lot of people have a biphasic T wave. A typical biphasic wave has two types of its own, one is terminal positivity and the other is terminal negativity. Why is it important? The biphasic T waves are known for dynamic change in polarity.

WebSep 18, 2015 · Twenty-six (41%) of 63 consecutive patients with triphasic waves had various types of metabolic encephalopathies while 37 patients (59%) had non-metabolic encephalopathies, usually senile dementia. Triphasic waves were not found to be specific for any single type of metabolic encephalopathy. WebTriphasic waves (TWs) are likewise generalized and periodic EEG waveforms seen in a wide array of encephalopathies. TWs have specific characteristics that are thought to distinguish them from other forms of GPDs.
