These leads encircle the precordium and provide information about the anterior, posterior, right and left forces.
EMS a programmers guide to c# 5.0 pdf responders should be trained and equipped to obtain 12-lead ECGs.
The EMS stat 12-Lead is a compact pocket-sized visual aide, used to assist the clinician in interpreting 12-lead ECGs.
An out-of-hospital 12-lead ECG and advanced notification of the ED can reduce time to reperfusion.This visual aid is easy to use and can be placed on most 12-lead ECG.The electrodes for the these leads are placed directly over the heart itself.The limb leads I, II, III, aVR, aVL, and aVF provide information about the superior, inferior, rightward, and leftward forces.Six limb leads (three bipolar and three unipolar) and six driver for sd card reader windows 7 precordial leads make up the standard 12-lead ECG.Electrodes of opposite polarity make up a bipolar lead.In addition, the EMS stat 12-Lead creates a systematic approach to looking at and identifying abnormalities within a 12-lead ECG.The six precordial leads are also called the chest leads.One positive electrode and a reference point make up a unipolar lead.The ECG LeadsThe electrocardiogram (ECG) traces the variation in voltage produced by the heart muscle during depolarization and repolarization.The standard ECG records depolarization and repolarization along designated paths called lead systems.Each lead traces the electrical activity between two points.American Heart Association, Handbook of Emergency Cardiovascular Care for Healthcare Providers 2006.24.
