What is a precarrid lead?
Presordial lead refers to one of the six standard electrocardiograms (ECG or ECG) or the electrodes placed on the chest to obtain a 12-core ECG message graphically showing the electrical activity of the heart. The 12-Wedding ECG consists of 12 different views of the axis to the heart obtained from 10 different wires: six precordial wires and one on each limb. Dr. Frank Wilson introduced the use of precordial wires in the 40th century to measure cardiac electrical activity closer and this standard remained a routine, except where the tread belt tests are necessary to modify. Each precordial lead is marked as "V" along with the electrode number, such as "V1" or "V3".
Six predordial wires are located on the front chest in a standard configuration. V1 is placed on the right side of the chest on the fourth intercostal or rib, while the V2 is placed directly over the chest on the left side of the chest. V4 is located on the fifth intercostal space under the center of the left collarbone. Work back, precordial lead V3 is applied directly between V2 and V4. V5 and V6 are located on the same level as the V4 on the left front axillary line and the left midaxillary line.
The use of 10 electrodes allows evaluation of the electrical activity of the heart along 12 different axes and three separate planes. 12-head ECG measures heart electrical activity along the X axis that divides the heart into the right and left half; along the y axis that divides the heart into the front and back half; and along the Z -axis that divides the heart into the upper and lower half. This level of evaluation leads to a large amount of data replication with eight independent potential customers and four redundant electrodes. According to Malivo and Ploonsey, bioelectromagnetism , however, all 12 potential customers are recorded to improve the repository formula and thus improve the diagnostic value of the ECG evaluation.
the post of each precordial guidance to allThis information along 12 axes and three planes of the dividing heart allows very close identification of the injury area. Lack of oxygen or ischemia can cause temporary changes in specific ECG potential customers. The heart infarction or myocardial infarction (Mi) results in developing changes in various predordial wires depending on the specific area of heart attack - for example, front, rear or lower - because electrical pulses are interrupted due to tissue and death damage.
