WebFeb 10, 2024 · 1.5: Rhythm Interpretation. Each EKG rhythm has “rules” that differentiate one rhythm from another. Rules for each rhythm include paramters for measurements like rate, rhythm, PR interval length, and ratio of P waves to QRS complexes. Today we will focus only on lead II. Each “lead” takes a different look at the heart. WebNov 27, 2024 · An accelerated junctional rhythm (rate >60) is a narrow complex rhythm that often supersedes a clinically bradycardic sinus node rate (see images below). The QRS complexes are uniform in shape, and evidence of retrograde P wave activation may or may not be present. Junctional bradycardia due to profound sinus node dysfunction.
