Measuring Einthoven II ECG and reference EMG simultaneously to be able to benchmark noise reduction algorithms

This database contains ECG and EMG recordings of 15 participants: - The first channel records from right wrist to left hip (ECG+EMG). - The second channel records from right wrist to right upper arm or right shoulder (EMG only). Data Format: .tsv (tab separated): samplingNumber ECG+EMG EMGonly checkDigitRow The sampling frequency is 250 Hz. Each recording is approximately 120 seconds long. The signal is in V (raw data straight from the ADC) The video recordings are synchronised with the data recording. There are 1 clean (no movement) and 3 types of forearm movements for each participant: 1. recording with relaxed arm and minimal EMG pollution 2. voluntary arm muscle contraction at approximately 0-15, 25-35, 45-55, 65-75, 85-95, 105-115 seconds of the recording. 3. voluntary arm muscle contraction at approximately 25-35, 45-55, 65-75, 85-95, 105-115 seconds of the recording. 4. voluntary arm muscle contraction during the 120 seconds of the recording.
