The ECG findings of an acute posterior wall MI include the following: ST segment depression (not elevation) in the septal and anterior precordial leads (V1-V4). This occurs because these ECG leads ...
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 ...
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.
