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
