ECG Electrocardiogram Amplifier
Part #: ECG100C

The ECG100C Electrocardiogram Amplifier records electrical activity generated by the heart and will reliably record ECG from humans, animals and isolated organ preparations. The ECG amplifier output can be switched between normal ECG output and R-wave detection. The R-wave mode outputs a smoothed pulse with the occurrence of each R-wave. The exact timing of the R-wave is detected even under conditions of extreme signal artifact. The amplifier also includes a user-switchable baseline stabilizer.

The ECG100C  is part of a complete research system solution (See System Overview). These amplifiers interface with the MP150 data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications.

Use the AcqKnowledge software to provide a complete Lead II ECG analysis. The software automatically scores the data and extracts the measurements of interest on a cycle-by-cycle basis. The results are automatically exported to Excel or pasted in the Journal file. AcqKnowledge also includes a fully automated HRV analysis feature. The HRV analysis provides values for VLF, LF, HF, VHF, sympathetic, and vagal, as well as the sympathetic / vagal balance.

12-lead ECG Options

  • For full, simultaneous, 12-lead ECG recording, use a total of eight ECG100C amplifiers and a WT100C Wilson terminal (virtual reference). Use two ECG100C to record Leads I and II, from which the software will calculate Lead III, aVR, aVL and aVF, and use six ECG100C to simultaneously generate the six precordial chest leads (V1-V6).
  • To generate a 12-lead recording using seven simultaneous leads with a single precordial chest lead appended in data segments, use three ECG100C amplifiers and a TSD155C multi-lead ECG cable (which incorporates a built-in Wilson Terminal). Use two ECG100C to generate Leads I and II, from which the software will calculate Lead III, aVR, aVL and aVF, and use the other ECG100C with the TSD155C to record one (movable) precordial lead [V1, V2, V3, V4, V5 or V6] in appended data segments.
MRI/CT Scan Trigger Option
  • To trigger an MRI System or CT Scanner with the occurrence of the R-wave present in animal (high frequency) ECG or respiratory data for gating purposes, use the DTU100 Digital Trigger Unit.

  • This is an algorithmic method to extract the R-Wave timing from a possibly corrupted ECG, or one where the R-wave is suppressed. BIOPAC R-wave detectors in the ECG100C and ECG100C-MRI both employ this strategy for detecting R-waves, as an option.
