if: test RVH did not pass
and R amplitude  300 µV and R duration  30 ms in V1
and R amplitude

700 µV and R duration

40 ms in V2
and no Q wave in V2
and R/S ratio in V2

1
and positive T amplitude

negative T amplitude in V1 and V2
or negative J amplitude > 100 µV and positive T amplitude

100 µV in V2
and test inferior infarct passed
or Q amplitude > 100 µV and R amplitude < 1500 µV and Q/R rat  0.2 in V6
or
