Key result
Pulse transit time serves as a surrogate semi-quantitative monitor of abrupt blood pressure changes, though it lacks the accuracy required for beat-to-beat blood pressure measurement.

PTT unsuitable for beat-to-beat BP monitoring; leaves open its surrogate role for abrupt changes pending prospective validation.
Does pulse transit time accurately measure beat-to-beat blood pressure or abrupt blood pressure changes?
PTT is a non-invasive technique that, while not accurate enough for beat-to-beat BP monitoring, shows potential as a surrogate marker for abrupt BP changes and disease-specific cardiovascular reactivity.
Foo et al. (2006) conducted a review in Cardiovascular diseases / Blood pressure variations. Pulse transit time (PTT) was evaluated. Pulse transit time serves as a surrogate semi-quantitative monitor of abrupt blood pressure changes, though it lacks the accuracy required for beat-to-beat blood pressure measurement.
