yes most common is sinus tachycardia..

n the theme behind all ecg findings is sudden acute right heart strain.., or u can say acute cor pulmonale...
so other findings observed are
  • sudden onset of RBBB with typical symptoms,, i.e QRS >120ms, RR' pattern in V1, V2, wide S wave in V5 OR V6.
  • S1 Q3T3 which means
S wave in lead I : complete or incomplete RBBB

Q wave and T wave inversion in lead III: repolarization abnormalities of RV
  • T wave inversion in V1 to V3
  • low amplitude deflections may be seen
but ECG is non sensitive n non specific for PE. Its main use in PE is to rule out MI

There is no single common finding
As said in the previous comment
1- RBBB (complete or in-complete)
2- sinus tachycardia
3- other arrhythmia may happen
4- S1 Q3 T3 (statistically this is the most common change)
