Final answer:
VT, or ventricular tachycardia, is a fast heart rhythm from the heart's ventricles. 'VT chapter page' seems to refer to certain criteria in medical documentation or education, but is not standard terminology. The specifics of VT categorization can depend on the context or source material.
Step-by-step explanation:
The term VT stands for ventricular tachycardia, which is a type of cardiac arrhythmia characterized by a fast heart rhythm originating from the ventricles of the heart. The phrase VT chapter page is not a standard medical term and may refer to a specific protocol or documentation in a medical textbook or resource. Generally, in a clinical context, ventricular tachycardia is considered sustained if it lasts more than 30 seconds or requires intervention due to hemodynamic instability. However, if 'VT chapter page' refers to educational material or guidelines, the number of consecutive beats that define VT or the criteria to trigger a new chapter or page in a protocol could vary based on the source material in question.
