Two future lines of action are available for automating macro-pattern identification in ICP signals: achieving strict agreement on morphological characteristics of “traditional” B waveforms, or starting a new with a fresh computerized approach for recognition of new clinically relevant patterns. Definitions and etiologies are still unclear, which makes systematic and standardized detection difficult. These terminologies appear to be interchangeable and seem to be used indiscriminately, with some papers using more than five different terms.

In total, 19 different terms were found, B waves being the most common. A literature search was carried out using PubMed/MEDLINE, with the following search terms: B waves + review filter, slow waves + review filter, ICP B waves, slow ICP waves, slow vasogenic waves, Lundberg B waves, MOCAIP.

MethodsĪ systematic review protocol including search strategy and eligibility criteria was prepared in advance. To better understand B wave characteristics and ease their detection, a literature review was carried out. Several competing terms exist, addressing either their probable physiological origin or their physical characteristics. Although B waves were introduced as a concept in the analysis of intracranial pressure (ICP) recordings nearly 60 years ago, there is still a lack consensus on precise definitions, terminology, amplitude, frequency or origin.
