Think of things backwards. These are the septal and anterior ECG leads. The MI is posterior (opposite to these leads anatomically), so there is ST depression instead of elevation. Turn the ECG ...

so a large amount of myocardial or conduction tissue must be damaged to block the posterior fascicle. Right axis deviation of 90 to 180 degrees The presence of a qR complex in lead III and a rS ...

The purpose of this study was to evaluate whether the 12-lead ECG could be substituted by ECG sets with a limited number of leads. Materials and methods: The performance of three ECG systems (ie ...

The rhythm is regular at a rate of 130 beats/min. A P wave occurs before each QRS complex (+) with a stable PR interval (0.14 sec). The P wave is positive in leads I, II, aVF, and V4-V6.
