Filtering of ECG signals in predefine respiratory frequency band is also a well-known technique to extract the respiratory signal from the ECG . The filtering techniques for extraction of the respiratory signal from the ECG are not suitable when respiratory frequency lies outside the predefined respiratory frequency band.
the usual way of recording ECG is by 12-lead ECG. before going to depth lets first understand the difference b/w a ECG lead & an electrode. electrode-it simply means the metal plate used to detect electrical currents of heart in any location. ECG lead-it shows the differences in voltages detected by electrodes.
