【Abstract】

<正>There is now convincing evidence that blood pressure (BP) variability (BPV) is an independent cardiovascular risk factor that should be considered as such and, therefore, might become an important target for therapeutic interventions. A proper evaluation of all components of BPV requires that continuous measurements of BP be obtained in conscious subjects, either intra-arterially in animals or by means of finger photoplethysmography in humans. BPV can be studied in both the time and frequency domains. Time-domain analysis of BPV is mainly based on the calculation of the standard deviation of
