There are some tricks to save you time, but first think about a normal EKG plot; in a normal EKG both leads I and AVF will be positive as the signal travels from the SA node (top right of the heart) to the tip of the ventricles (bottom left of the heart). This is a normal axis, and leads us to the rule of Normal PR interval: 0,12–0,22 seconds. The upper reference limit is 0,20 seconds in young adults. A prolonged PR interval (>0.22 s) is consistent with first-degree AV-block. A shortened PR interval (<0,12 s) indicates pre-excitation (presence of an accessory pathway). A positive QRS in Lead aVF similarly aligns the axis with lead aVF. Combining both coloured areas – the quadrant of overlap determines the axis.

Lead I more positive than aVF. The axis will therefore be oriented more toward 0°. Normal axis ~ 20° - 40° ECG#3 : Lead I positive. Lead aVF almost equiphasic. Therefore, the axis will be approaching 0°.

Normally precedes the QRS complex and is upright in leads: I, II, aVF, and V4 and V5. Inverted (negative) in leads II, aVL and V1 and V2. Duration of P wave is usually under 0.1 Second. Amplitude should be 0.5-2.5 mm when viewed in lead II.

However, a negative T wave is normal in lead aVR. Lead V1 may have a T wave with positive, negative, or biphasic where positive is followed by negative, or vice versa.

Limb leads: I, II, III, IV, V, and VI Hypertrophic cardiomyopathy is the thickening of the left ventricle, occasionally right ventricle. It may be associated with left ventricular outflow tract obstruction or may not be associated with it in 75% of the cases. ECG would be abnormal in 75 to 95% of the patients.

May 3, 2018 The PR, QRS, and QTc intervals are all normal. As for the aVL/aVF reversal, we must remember that aVL/aVF/aVR are all augmented leads
