twelvelead
A twelve-lead electrocardiogram (12-lead ECG) is a noninvasive diagnostic test that records the heart's electrical activity from twelve distinct viewpoints. The recording uses ten surface electrodes placed on the limbs and chest to produce twelve standard leads, providing a comprehensive view of cardiac conduction and rhythm.
Lead configuration and electrode placement: Three limb electrodes are placed on the arms and legs to form
Clinical uses: The 12-lead ECG is used to detect myocardial ischemia or infarction, arrhythmias, conduction abnormalities
Limitations and interpretation: Accurate interpretation depends on correct electrode placement and patient factors. Artifacts from movement,
