EKG Week 1

Dysrhythmia Analysis – “3 Rs”
• Determine Rhythm (Measure distance
between R-R intervals along strip)
Dysrhythmia Analysis – “3 Rs”
•Determine Rhythm (Measure distance bet. R to Rs
–Regular (R to R distances even)
–Irregular (R to R distances not even)
–Absent
Dysrhythmia Analysis – “3 Rs”
• Determine Relations(hips) & Durations
– # of Ps to # of QRSs (1 P for each QRS)
– Present
– Related
– Absent
“Quickie” Analysis:
– QRSs: present? −P waves: normal?
– Ps to QRSs: present, related?
Always evaluate the patient’s clinical status to
determine toleration of rate & rhythm.

• Site Classification:
– Sinus – Junctional
– Atrial – Ventricular
• Mechanism Classification:
– Bradycardia (<60 bpm)
– Tachycardia (>100 bpm)
– Prematurity (early beat, check site of origin)
– Escape (late beat, check site of origin)
– Flutter
– Fibrillation
– Conduction Defects
