Multi-Lead ECG and MAP Measurement Options for IH-5 Langendorff or Working Heart
For multi-lead ECG and MAP measurements on functional IH-5 Langendorff or working heart systems, up to 12 ECG leads are combined with up to 8 MAP electrodes.
The Monophasic Action Potential (MAP) electrodes work based on the principle of Franz et al whereby firm, stable contact of the MAP electrode results in a high-quality MAP. MAP recording has been utilized in cardiac physiology for decades as it allows regional assessment of the electrophysiological state of the intact heart.
Input boxes with circular MAP holders are available for various configurations.
For other options available for the IH-5 system, please see Single-Lead ECG and MAP Measurement Options for IH-SR or IH-5 Langendorff or Working Heart.
For multi-lead ECG and MAP measurements on functional IH-5 Langendorff or Working Heart systems, up to 12 ECG leads are combined with up to 8 MAP electrodes for measurement on rat, guinea pig or rabbit hearts.
The Monophasic Action Potential (MAP) electrodes work based on the principle of Franz et al whereby firm, stable contact of the MAP electrode results in a high-quality MAP. For electrophysiology studies, up to 12 ECG leads can be combined with up to 8 MAPS on a functional IH-5 system. These options are particularly suited for safety pharmacology laboratories.
- 6-lead ECG measurements are accomplished using Einthoven Goldberger leads and the PLUGSYS Einthoven Goldberger (EGM) module.
- 12-lead ECG measurements are accomplished using a combination of Einthoven Goldberger leads and Wilson leads with the PLUGSYS Einthoven Goldberger (EGM) and Wilson (WLA) modules. 12-leads ECGs are required for drug studies.
- MAP measurements use MAP electrodes with the PLUGSYS Monophasic Action Potential (MAPM) module.
- Input boxes with circular MAP holders are available for configurations that require them.
Applications
MAP recording is essential to researchers who study:
- Cardiac mapping
- Dispersion of ventricular repolarization
- Arrhythmias characterization of regional ischemias using MAP,
- Activation time and similar applications.
Options
You can make up to 12 ECG measurements alone or up to 12 ECG combined with up to 8 MAP measurements on a functional IH-5 system. Simply choose a combination of the following ECG and MAP options that suit your application. Measurements of 6 to 8 MAP, with or without ECG, require an Input Box.
