When ectopic impulses from the anterior wall of the right atrium produce a completely negative P wave in lead V1, the posterior wall ectopic impulse produces a positive and negative biphasic P wave.
When sinus arrest occurs, the electrocardiogram will show a long P-P interval, which is not multiples of the basal sinus cycle, including physiological and pathological reasons.
When ectopic impulses from the anterior wall of the right atrium produce a completely negative P wave in lead V1, the posterior wall ectopic impulse produces a positive and negative biphasic P wave.
Sinus heart rate less than 60 beats per minute in adults is called sinus bradycardia. A sinus heart rate of 40 to 50 beats per minute is moderate sinus bradycardia, and patients may have symptoms such as palpitations and dizziness.
On a 12 lead electrocardiogram, analyzing the morphology and polarity of ectopic P-waves can determine the approximate anatomical location of ectopic atrial foci.
Sinus heart rate less than 60 beats per minute in adults is called sinus bradycardia. A sinus heart rate of 40 to 50 beats per minute is moderate sinus bradycardia, and patients may have symptoms such as palpitations and dizziness.
When ectopic impulses originate in the left atrium, an upright P wave will be generated in V1 and an inverted P wave in lead aVL.

R wave greater than S wave is judged to be positive; R smaller than S is judged to be negative; R equal to S amplitude is judged to be equipotential.

In acute left main occlusion, the left ventricular myocardium is massively ischemic and necrotic, the excitatory potential of the left ventricle is weakened, and the axis may deviate to the right .

When the frontal QRS axis is at +83, the R amplitude of lead aVF is the highest.The frontal QRS axis is almost perpendicular to the axis of lead .
In the frontal lead system, the lead axes of the 6 limb leads form a hexaxial reference system, which is one of the important theories of electrocardiography.
