Cardiology An EKG generated from a 12-lead EKG–leads I, II, III, aVR, aVL, aVF, V1–V6. See Electrocardiogram. McGraw-Hill Concise Dictionary of Modern Medicine. © 2002 by The McGraw-Hill Companies, Inc. Want to thank TFD for its existence? Tell a friend about us, add a link...
Lead IIhas themostpositivedeflectioncompared to leads I and III. Normal Cardiac Axis Right axis deviation Typical ECG findings forright axis deviation: Lead IIIhas themostpositivedeflection, andlead Ishould benegative. Right axis deviation is associated with right ventricular hypertrophy. Right Axis De...
Thereafter, the impulse moves through the electrically predominant left ventricle in an inferior and rightward direction, thus explaining the S waves in leads I and aVL as well as the R waves in leads II, III, and aVF. Radiologic studies of the human heart in situ have shown that the ...

The limb leads, of which there are six (I, II, III, aVF, aVR and aVL), have the exploring electrode and the reference point placed in the frontal plane. These leads are therefore excellent for detecting vectors traveling in the frontal plane. The chest (precordial) leads (V1, V2, V3...

As a general rule if the net deflections in leads I and aVF are positive then the axis is normal. If lead I has a net negative deflection whilst aVF is positive then there is right axis deviation. If lead I has a positive deflection and aVF has a negative deflection then there is left...
Normal Amplitude: .5 mm in limb leads Normal Deflection: I, II, V3-V6 Normal Duration: 0.1 – 0.25 sec The QT Interval indicates both depolarization and repolarization ventricular activity. The QT Interval begins at the start of the QRS complex and ends at the completion of the T-Wave. ...
