Compatibility


AcqKnowledge software utilizes guided channel setting dialogs, allowing the user to easily configure all channel data types and parameters. Once parameters are established, recording settings can be saved as a graph template for future use. This allows for instant start up for subsequent recording sessions.

Left Ventricular Pressure Data

Left Ventricular Pressure data with calculated dP/dt waveform in AcqKnowledge

During recording, see real-time live raw data as well as real-time filtering or calculation channels. Display Rate, dp/dt, systolic, and diastolic pressure in real-time during recording, or choose from a variety of other filter and calculation settings. Easily insert markers for different stimuli presentation or experimental conditions throughout recording.

Physiological data can also be synchronized to video recording via BIOPAC Camera Systems. With Camera Systems physiological data and Video Data are time linked in AcqKnowledge. Simply scroll through either the video or physiological data to be taken to the corresponding data point in the other file.

After recording, take advantage of fully automated hemodynamic analysis routines in AcqKnowledge. Use guided video tutorials to get the most out of all available analysis tools.

Left Ventricular Pressure Automated Analysis Package Overview

Left Ventricular Pressure Classifier and Analysis

The Left Ventricular Pressure Analysis routine automatically locates systolic and end diastolic events on LVP signal. LVP Classifier first places markers and values on the waveform and then the full analysis extracts cycle-by-by-cycle measurements from the data.

Extracted measures include:

  • Contractility index
  • Developed pressure
  • dP/dt Max
  • dP/dt Min
  • End diastolic pressure
  • Minimum pressure
  • QA Interval QA
  • Rate – heart rate in BPM
  • Recovery time
  • Systolic pressure
  • Tau
  • Tension time index

See the LVP Classifier and Analysis in action:

 ABP Classifier & Analysis

Use this analysis routine to automatically place systolic and diastolic events on ABP signal. Use with invasive or noninvasive recordings! Get relative Q measures by also incorporating a Lead II ECG signal. Analysis extracts cycle-by-by-cycle measurements from the data.

Arterial BP and Left Ventricular BP Analysis Measurements include:

  • dP/dt Max
  • dP/dt Min
  • Minimum pressure
  • QA Interval
  • Recovery time
  • Diastolic pressure
  • Systolic pressure
  • Heart rate
  • Recovery Interval
  • Tau (LVP)
  • Tension time index (LVP)
  • Ejection time (ABP)
  • Mean blood pressure (ABP)
  • Time to peak pressure (ABP)

See the ABP Classifier and Analysis in action:

ECG Interval Extraction

Extracts cycle-by-cycle measurements from ECG waveform and places ECG complex markers on graph.

ECG Interval Extraction measures include:

    Corrected QT interval
    Heart rate
    P height
    PRQ interval
    QRS width
    QT interval
    R height
    RR interval
    ST interval

HRV Poincare Plot

Produces XY Plot of RR Intervals vs RR Intervals delayed by one beat (RR vs. RR+1). Use this routine to visually inspect for patterns in the sequence.
