As a non-invasive yet most appreciated indicative tool, the 12-lead ECG records the heart's electrical activity as waveforms. When understood precisely, an ECG can notice and monitor a host of heart circumstances - from arrhythmias to coronary heart disease to electrolyte imbalance.
Since the first telecardiogram was logged in 1903, huge paces have been made in the recording and clarification of ECG. Today, the 12-Lead ECG remains a typical investigative tool among paramedics, EMTs, and hospital staff. To gauge the heart's electrical activity precisely, proper electrode placement is crucial.
In a 12-lead ECG, there are 12 principals intended using 10 electrodes bought from ECG Electrodes Providers.
Chest (Precordial) Electrodes and Placement
» V1 - Fourth intercostal part on the right sternum
» V2 - Fourth intercostal part at the left sternum
» V3 - Halfway between placement of V2 and V4
» V4 - Fifth intercostal part at the midclavicular line
» V5 - Frontal axillary line on the same flat level as V4
» V6 - Mid-axillary line on the same flat level as V4 and V5
A lead is an indication of the electrical activity of the heart from a specific angle. Put merely, a lead is like a standpoint. In 12-lead ECG, 10 electrodes are delivering 12 standpoints of the heart's activity using diverse angles through two electrical planes - perpendicular and horizontal planes.
The exact assignment of each electrode on the patient is significant. Improper placement can lead to an untrue or misleading diagnosis.
Make sure the electrode conducting cream is fresh and sufficiently moist. A dry electrode with insufficient cream reduces the conduction of the ECG signal.
Often, electrode cream dry-out is a result of improper storage. Store electrodes as ordered by ECG Electrodes Providers in India and do not remove them from their bag until they're ready for use.
Do not position electrodes on the skin over bones, cuts, irritated skin, and body parts where there is lots of conceivable muscle movement.
