Webmeasurements of the width and the depth of Q waves in inferior leads (leads II, III, or aVF) were performed. A Q wave duration of >40 ms. and a depth of the Q wave of >-0.2 mV were considered suggestive of inferior wall myocardial infarction. In addition, the deviation of the ST segment from the baseline by more than 1 mm and WebECG criteria for pathological Q-waves (Q-wave infarction) Individuals with electrical axis 60–90° often display a small q-wave in aVL.

WebPulmonary embolism may cause ST segment elevations in V1, V2, II, aVF and III. However, the most common ECG finding in pulmonary embolism is sinus tachycardia. Occasionally the S1Q3T3 pattern may be seen; this means that there is a prominent S-wave in lead I, large Q-wave in lead III and T-wave inversion in lead III. WebThe slow spread of the impulse will result in a slow (and abnormal) activation of the right ventricle, which yields a bizarre and prolonged QRS complex on ECG. The hallmark of right bundle branch block is QRS duration ≥0,12 seconds, large R'-wave in V1/V2 and a broad and deep S-wave in V5/V6. Figure 2 illustrates a normal ECG, a right bundle ...
