ECG: The augmented limb leads aVF, aVR and aVL

Описание к видео ECG: The augmented limb leads aVF, aVR and aVL

We show how to record the augmented limb leads of the ECG. This is done by using two resistors which join two limbs together and then connect to the negative input of the amplifier. The positive input of the differential amplifier is then connected to the remaining limb and so on. This gives us aVF, aVR and aVL. With the resulting aVF it is then very easy to estimate the mean electrical vector of the heart which is also demonstrated in this clip.
