Question

Quizplus · Accepted Answer

Sinus rhythms are characterized by the presence of a uniform shape P wave preceding each QRS complex. This indicates that the electrical impulse is originating from the sinus node in the atria and spreading through the heart in a normal way. Multiple shapes of P waves, a wavy baseline or inverted P waves in Lead II would indicate an abnormal rhythm or conduction pathway.
