Lead aVF: The augmented unipolar left leg lead (feet). It is oriented toward the inferior surface of the heart. Electrical current from the heart is traveling toward the feet. Image 16: Augmented Leads Standard leads, plus augmented leads make up the first six of a 12-lead ECG. Surprise!
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 le...

This activity is recorded using an electrocardiographic machine connected to the patient with four electric leads (labelled 1, 11 ,111, AVR, AVL, AVF) on the ankles and wrists and six on the front of the chest over the heart area (labelled V1-6). The normal pattern of the EKG allows...
due to Ca. ST segment on EKG Phase 3 – rapid repole – Ca close, K out ; T wave Phase 4 – resting – cell memb closed to Na, K moves in – diastol Fast response – not SA, AVN, no pacemaker. Don’t initiate, stim by other cells. T-hold leads to Na ch. open Phase 1...
aVL, aVF) • the 3 limb leads form an imaginary inverted triangle over the heart = Einthoven’s triangle • There should be a square wave calibration to show that 1mV is equivalent to 1cm in height. • Speed should be 25mm/sec. Hence 1 large square is 200msec ...
Leads aVR, aVL, and aVF measure positive electrical charges through a single electrode and a reference point having zero activity. Leads V1 through V6 are unipolar leads consisting of a single positive lead and a and a negatively charged reference point. ...
