Single-Lead ECG and MAP Measurement for IH-SR and IH-5 Langendorff or Working Heart

Single-Lead ECG and MAP Measurement for IH-SR and IH-5 Langendorff or Working Heart

For single-lead ECG and MAP measurements on functional IH-SR or IH-5 Langendorff or working heart systems. ECG and MAP are recorded to be analyzed together.

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.

For single-lead ECG and MAP measurements on functional IH-SR or IH-5 systems, one ECG lead is combined with one MAP electrode.

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.

For additional options available for the IH-5 system, please see Multi-Lead ECG and MAP Measurement Options for IH-5 Langendorff or Working Heart.

Features & Benefits

  • Mini monophasic action potential electrodes for epicardial and endocardial recording, with dedicated holders 
  • Precision MAP electrodes with dedicated holders allow easy positioning on the heart
  • Small electrodes allow multiple ECG and MAP signals to be recorded even on mouse hearts 
  •  Mini ECG electrodes with dedicated holders 
  •  Flexible ECG electrodes follow the heartbeat, dedicated holders allow easy positioning on the heart 
  •  Optimized coaxial pacing electrode 
  •  Reduced stray fields from the pacing electrode for more accurate recordings


Applications

MAP recording is essential to researchers who study:

  • Atrial fibrillation
  • Arrhythmias
  • Anti-arrhythmic drugs
  • Ischemia
  • Depolarization and repolarization cycles
  • Activation time
  • Mechanisms of action of various drugs

MAP Electrodes

The MAP electrodes required for each application, species and system are included in the options above.

Micro MAP-Tip Electrode (73-3840) for single epicardial MAP on IH-SR with mouse heart includes the electrode, spring wire and pack of sponges, as well a 2 mm male connector. The MAP electrode opposite holder (73-3858) needs to be attached with a certain pressure to the heart on the opposite side to hold the heart in position.

Mini MAP-Tip Electrode (73-0150) for single epicardial MAP on IH-SR (rat, guinea pig heart) or IH-5 (rat, guinea pig, rabbit heart) comes with two male connectors and includes one pack of sponges. The MAP electrode opposite holder (73-2989) holds the rat or guinea pig heart in place at a certain pressure.

MAP Electrode for Intracardial MAP (73-3715) for endocardial MAP on IH-SR or IH-5 (rat, guinea pig, rabbit heart) includes necessary holders.
