Regarding thrombolysis for pulmonary embolism (PE):
a) ECG pattern: S1 Q3 T3 is an indication for thrombolysis.
b) If systemic hypotension is present, thrombolysis is contraindicated.
c) D-dimer is very helpful for diagnosis of PE but only a negative result is of any value.
d) Thrombolysis is first line treatment in non – massive PE.
