-This module creates a batch-compliant interface to integrate the Finapres Medical Systems BeatScope software in the ANSLAB environment (a Beatscope license is required). Raw data can be edited before starting the Beatscope analysis, and extracted parameters can be browsed, edited and exported using the ANSLAB user interface. Extracted parameters are systolic blood pressure, diastolic blood pressure, true mean blood pressure, heart rate, total peripheral resistance, left ventricular ejection time, cardiac oxygen supply (demand ratio), cardiac output, stroke volume, aortic characteristic impedance and total arterial compliance.+This module creates a batch-compliant interface to integrate the Finapres Medical Systems BeatScope software in the ANSLAB environment (a Beatscope license is required).

For ambulatory monitoring data files, an elaborated activity analysis is available to allow for the identification and stratification of activity levels across the day as a basis for the analysis of other physiological signals (activity stratification as control of activity confounds).

This allows, e.g., the computation for baroreflex sensisitivy from ECG and blood pressure signals, or computation of sufficient cardio-respiratory coherence (>0.5) at respiratory frequencies to assure reliable interpretation of high-frequency HRV as truly respiratory driven and thus reliable index of vagal activity.

 == Vocal response analysis == == Vocal response analysis ==
-This module extracts response latency (vocal reaction time) and response magnitude from recorded sound signals. A response plot successively displays each vocal resonse and allows identification of inadequate responses and drag-and-drop editing of baseline level, onset latency, and response level. Sound can be played back for verification during scoring or written to WAV-files for playback in sound editing programs. This tool allows for example exact and reliable scoring of computerized Stroop tests.+This module extracts response latency (vocal reaction time) and response magnitude from recorded sound signals.
