Two channel data acquisition software for electrophysiologic studies on papillary muscles or purkinje fibres in a horizontal tissue bath (e.g. HSE Steiert papillary bath).

The HSE-HA Data Acquisition Hardware for EPES software is available in three versions:

• PLUGSYS Version 73-0161

This version consists of the PCI A/D board DT301 and the cable for connecting to a DIM Data Interface Module installed in the PLUGSYS basic system case

• Stand Alone Version 73-0235

This version consists of the PCI A/D board DT301 and a BNC input box where signals from external amplifiers can be connected.

• Stand Alone USB Version 73-3330

Hardware requirements for EPES:

Both the PLUGSYS and stand alone versions require the following computer hardware:

• Computer PENTIUM III PC, 500 MHz or more with one free PCI slot
• RAM 128 MB or better 256 Mbytes
• Hard disk space With at least 20 GB
• Monitor 19 inch standard monitor or 17-18 inch flat panel monitor
• Floppy Drive 1.44 Mbytes, CD-ROM drive
• Operating System Windows® NT/2000 or XP
• Backup Media CD-recorder (burner)

Acquired signals: Intracellular Action Potential, Contraction Force.
Various parameters can be derived from these signals:
Calculated Parameters from AP:

• CT Conduction Time
• TOP Take Off Potential
• AMP amplitude, dV/dtmax maximum rate of depolarisation
• EOP Potential after the end of action potential
• APD90, APD75, APD50, APD25, APD10 (Signal duration @ 90, 75, 50, 25, 10%)

Calculated parameters from contraction force are:
• LP Latency period
• RT Resting Tension
• DevF Developed Force
• dF /dtmax and dF/dtmin
• RD Response Duration

Stimulator control can be added
