Basic Arrhythmia Interpretation Exam
Normal Sinus Rhythm - ANS -.12-.20s and constant
An EKG Rhythm Characterized By A Normal Rate And Rhythm, With All Wave Intervals In The Normal
Ranges.
Sinus Bradycardia - ANS -everything is normal except heart rate.
-Looks just like normal sinus rhythm except that the rate is below 60
Sinus Tachycardia - ANS --Looks just like normal sinus rhythm except that the rate is over 100
100-160 bpm, regular atrial and ventricular rhythm
Sinus Arrhythmia - ANS -Appearance is ALMOST NORMAL but if you calculate with calipers the QRS is
irregular
Sinus Arrest - ANS -irregular heart rhythm
one or more complete PQRST complexes missing.
After pause rhythm is DIFFERENT PQRST may come early or later but not on time.
Sinus Block - ANS -irregular heart rhythm
one or more complete PQRST complexes missing.
After pause Rhythm is AS EXPECTED. (caliper falls where it should regularly fall.
Premature Atrial Contraction (PAC)
THIS IS AN EVENT NOT A RHYTHM - ANS --normal underlying rhythm but some beats may be early and
the P wave will look abnormal
Atrial Tachycardia - ANS -Heart rate is 150-250 bpm , P wave may be flattened or notched and can blend
into the T wave making it difficult to read the P wave, everything else is normal.
