The bottom one or two lines will be a full rhythm strip of a specific lead spanning the whole 10 seconds of the ECG. Simply stated the galvanometer uses the ten leads to make twelve different recordings.
A rhythm that does not perfuse well can lead to impending heart failure quickly if not addressed.
12 lead ecg interpretation for dummies. 1 mm ST elevation in one or more of leads I II III aVL aVF V5 V6 or 2 mm ST elevation in one or more of leads V1-V4. ST elevation at the J point in at least 2 contiguous leads of 2 mm in men or 15 mm in women in leads V2V3 andor of 1 mm in other contiguous chest leads or the. A 12-lead ECG is made up of a tracing of the electrical activity of the heart from 12different points of view.
The point of view comes from the location of the positiveelectrode of each lead. The positioning of these electrodes is broken down into 3categories the limb leads lead I II III the augmented leads aVR aVL aVF andthe precordial or chest leads V1 V2 V3 V4 V5 V6. Interpret the 12-lead ECG in light of the history and clinical presentation.
When pre-test probability is high we take even subtle ECG signs more seriously. Conversely when the pre-test probability is low the ECG evidence must be compelling to. First the standard 12-lead ECG is a 10-second strip.
The bottom one or two lines will be a full rhythm strip of a specific lead spanning the whole 10 seconds of the ECG. Other leads will. The best advice I can suggest to people new at 12 lead interpretation is to fully look at one and just do the step by step approach.
