QT interval is measured from the start of the Q wave to the end 100 bpm range, A useful rule of thumb is that a normal QT is less than half the preceding RR. If an ECG is fortuitously captured while the patients heart rate is 60 bpm, the absolute QT interval should be used instead!A useful rule of thumb is that a normal QT is less than half the preceding RR interval. The rest of the ECG waveform—including the QRS com-plex, T wave, and QT interval—should appear normal because impulses through the ventricles are usually conducted normally.Potassium level should be within normal range before giving dofetilide and kept in normal range.

The axis on an ECG relates to the vector of the electrical signal. The vector is the direction the electrical impulse is travelling through the heart. Normal range for the P wave vector is between 0 and 75 degrees, for the QRS between 30. The frontal plane QRS axis in RBBB should be in the normal range (i.e -30 to 90 degrees).
