The Figure 1B ECG shows an increase in the amplitudes of QRS complexes. The loss of 13 lbs (5.2% of his BW) led to a rise of 35.1%, 24.2%, 18.1%, 2.3%, and 6.5% in aVR, ΣI&II, Σ6LimbLds ...

The standard ECG has 12 leads. Six of the leads are considered ... The six limb leads are called lead I, II, III, aVL, aVR and aVF. The letter “a” stands for “augmented,” as these ...

The axis of the ECG is the major direction of the overall ... The negative of lead aVR (R for right arm) is at +30 degrees; the positive of lead aVR is actually at -150 degrees.

Figure 2: An ECG obtained from a beagle dog 21 days later, showing six rhythm strips simultaneously (leads I, II, III, aVR, aVL and aVF). VPCs are the most frequent type of abnormal rhythm in dogs ...
