WebNov 22, 2024 · To use the heart axis calculator, you have to calculate the net amplitude of the QRS (see QRS morphologies ). Subtract the Q wave and the S wave amplitude from the R wave amplitude. If the result is negative, the minus sign must be used (for example, -2). QRS = 12 mm. QRS = 1 mm (R wave: 7 mm - S Wave: 6 mm). WebQts is the total Q of the speaker. It is defined as 1/Qts = 1/Qes + 1/Qms. Qtc: Qtc is the total Q of the speaker in an enclosure including all system resistances. A Qtc of .707 is the most common and generally produces the flattest frequency response with approximately a 12dB/octave rolloff.
