In the frontal plane lead system, when the initial vector of the QRS wave is directed downward, the positive initial QRS wave is recorded in leads II, III, and aVF.
In the frontal lead system, when the initial vector of the QRS wave points upward, the II, III, and aVF leads record a negative initial QRS wave, i.e., a small q wave.
During ventricular depolarization, a spatial QRS loop is generated, projected onto the frontal lead system, forming the frontal QRS loop, which further forms the electrocardiogram.
