Sensor Range Information:
- 200 to 4,000µV
The ECG sensor measures the electrical energy generated during a heartbeat. To record the classic PQRST wave, the sensor's three electrodes can be attached to the skin of the user's forearms using disposable ECG patches.
The sensor is supported with a comprehensive user guide (available from the Resources tab). Each sensor is supplied with a pack of 100 disposable ECG electrode patches.
As the average heart cycle is typically 0.7 to 0.8 seconds this Sensor is best used with an EasySense logger capable of fast logging e.g. EasySense VISION, QAdvanced, 3Link, 1Link. A logger capable of only 10-bit resolution (e.g. Q3+, Q5+ or Flash Logger) may not capture enough detail.
- Comparing the ECG to the waveform produced by the Heart Rate Sensor
- Comparing the ECG of a rested heart to an exercised heart
- What happens to the ECG trace if a sensor lead location is changed
- Understand the meaning and relationships of the PQRST waveforms
- Investigate the effect of mild stimulants (caffeine)
The ECG sensor has 3 sensor leads. The change in electrical energy is detected by two leads and referenced to a ground signal. The changes in energy are displayed as a waveform. As the electrical changes being detected are very small and prone to disturbance, it is vital that the test subject is relaxed, and motionless. Please note that this product is designed for demonstration of the ECG waveform, it is not designed or intended to be used for medical diagnosis.
Supplied with a pack of 100 disposable ECG electrode patches. Additional ECG Patches (3286) are available in packs of 100.
