When the left free wall and septal accessory pathway are excited, preexcitation waves with different polarities are generated in leads and aVL.

On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
When the ventricular preexcitation wave leaves the baseline and then falls back to the baseline, it is interpreted as an isoelectric line preexcitation wave.
When the left anterior wall and posterior wall accessory pathway are excited, preexcitation waves with different polarities are generated in the inferior wall leads of , and aVF.
Ventricular preexcitation is the pre excitation of a portion of the ventricular muscle by the accessory pathway, forming a rough and dull, and fuzzy wave that can be positive, negative, or biphasic.
Ventricular preexcitation is a fusion wave formed by the accessory pathway and normal atrioventricular conduction system exciting a part of ventricle respectively.
When ventricular preexcitation components occupy different proportions of QRS waves, the measured PJ intervals are different.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
The polarity of ventricular preexcitation waves can be positive, as shown in Figures A and B, or negative, as shown in Figures C and D.
When there is a left ventricular free wall bypass, the polarity of the ventricular preexcitation is positive in lead V1 and negative in lead aVL on the electrocardiogram.
Surrounding the atrioventricular ring, except for the anterior septum of the left ventricle, there is no distribution of accessory pathways, and accessory pathways can exist in other parts.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
On the electrocardiogram, observing the morphology of QRS waves in lead V1 can distinguish whether ventricular pre excitation is located in the left ventricle or the right ventricle.
On the electrocardiogram, the PJ interval is used to distinguish between ventricular heartbeats and ventricular pre excitation. The normal value of PJ interval is less than 270ms.
