The ECG sensor ML84m measures electrical potentials produced by the heart (Electro- cardiogram). These small voltages are measured at the skin of the wrists and elbow through electrodes. The ECG sensor can also be used to measure the electrical potentials generated by muscle cells when these cells contract and relax (Electromyogram). For safety reasons the sensor uses an optical coupler to avoid any direct electrical contact between the person whose ECG is measured and the measurement interface or computer. The ECG sensor is delivered together with a package of 100 electrode patches.
The ECG sensor can be used for various experiments such as:
• Monitoring ECG in rest and after mild exercise
• Investigating ECG changes with mild stimulants
• Studying the P, Q, R, S, T waveforms
• Studying the effect of different body positions on the ECG
• Recording the electrical activity of a muscle (EMG)
• Associate amount of electrical activity with strength of muscle contraction.
• Investigate the relation between the EMG and the force exerted by the arm.
The ECG sensor ML84m is a digital sensor (on-sensor digital conversion), which gives calibrated values of the measured quantity. This sensor can only
be connected to the CMA MoLab interface and not to other CMA interfaces such as VinciLab, CoachLab II+ or EuroLab.
Technical specifications of the sensor are described in its User's guide
