1. Sinus Bradycar- Regularity: atrial and ventricular rate are regular
dia Rate: < 60 beats per minute
P wave: upright, smooth, round and uniform shape, one for every QRS complex
PRI : 0.12 to 0.20 seconds
QRS: 0.06 to 0.10 seconds
QTI: 0.36 to 0.46 seconds
T wave: upright, smooth and round uniform shape
2. Sinus Tachycar- Regularity: atrial and ventricular rate are regular
dia Rate: >100 beats per minute
P wave: upright, smooth, round and uniform shape, one for every QRS complex
PRI : 0.12 to 0.20 seconds
QRS: 0.06 to 0.10 seconds
QTI: 0.36 to 0.46 seconds
T wave: upright, smooth and round uniform shape
3. Sinus Arrhythmia Regularity: atrial and ventricular rate are the same but the rhythm will be slightly
irregular
Rate: variable, can be bradycardia to normal
P wave: upright, smooth, round and uniform shape, one for every QRS complex
PRI : 0.12 to 0.20 seconds

QRS: 0.06 to 0.10 seconds
QTI: 0.36 to 0.46 seconds
T wave: upright, smooth and round uniform shape
4. Sinus Arrest and Regularity: Regular but interrupted (by a pause)
Sinus Pause Rate: can occur at any heart rate
P wave: normal sinus P waves before the pause
PRI: 0.12 to 0.20 seconds before the pause, may be shorter or absent after the
pause
QRS: 0.06 to 0.10 seconds on the sinus beats, on the escape beats the QRS may
be narrow or wide depending on which pacemaker of the heart resumes after the
pause
QTI: 0.36 to 0.46 seconds for the sinus beats
5. Premature Atrial Regularity: underlying atrial rate is regular except for early beat, ventricular rate is
Contractions regular
PACs Rate: determined by the underlying rhythm
P wave: upright, smooth, round and uniform shape, EXCEPT for the premature
beat, it will shaped differently
PRI : 0.12 to 0.20 seconds except for early beat
QRS: 0.06 to 0.10 seconds and all are uniform
