This type of waveform is flat with no current flowing.

• positive

• negative

• isoelectric

This type of waveform is upright with current flowing to positive electrode.

• positive

• negative

• isoelectric

• bipolar

Augmented and precordial leads are

• unipolar

• bipolar

When measuring limb leads, go in the following order:

• LA -> LL

  RA -> LA

  RA -> LL

• RA -> LL

  RA -> LA

  LA -> LL

• LA -> RA

  LA -> LL

  RA -> LL

• RA -> LA

  RA -> LL

When evaluating augmented leads, aVR records

• activity from the heart to the right arm

• activity from the heart to the left arm

• activity from the heart to the left leg
