Single lead means it has 3 connecting leads. The traditional ECG machines have 6 leads. Computerized ECGs have 12 leads. Patient monitors inside OT/OR often have one lead. The Arduino based patient monitor board we discussed before is costly and actually never became hugely popular. The module can extract, amplify, and filter small biopotential signals. ECG is the recording of the electrical … [Read more...]
