WebA finding of S1Q3T3 [b] is an insensitive [10] sign of right heart strain. [11] It is non-specific (as it does not indicate a cause) and is present in a minority of PE cases.

WebThe ECG in all five cases showed sinus tachycardia and four of them showed an "S1Q3T3" pattern. This pattern is the pathognomic sign of right heart strain which consists of a deep S in lead 1, a Q-wave and an inverted T wave in lead 3. Sometimes inverted T-wave in V1 to V4 and incomplete RBBB are also seen. WebOccasionally 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. Moreover, T-wave inversions in lead V1–V3 are common in pulmonary embolism. Finally, a new right bundle branch block (RBBB) should always raise suspicion of pulmonary embolism in ...
