Normal Sinus Rhythm
Sinus node initiates
regular impulses at a
normal rate. Each
impulse is conducted
normally to the
ventricles.

Normal Sinus Rhythm
 Regularity: Regular
 Rate: 60–100 beats per minute
 P Wave: Normal and upright; one P
wave in front of every QRS complex
 PRI: .12–.20 seconds and constant
 QRS: Less than .12 seconds

Sinus Bradycardia
Sinus node initiates
regular impulses at a
slow rate. Each
impulse is conducted
normally to the
ventricles.

Sinus Bradycardia
 Regularity: Regular
 Rate: Less than 60 beats per minute
 P Wave: Normal and upright; one P
wave in front of every QRS complex
 PRI: .12–.20 seconds and constant
 QRS: Less than .12 seconds

Sinus Tachycardia
Sinus node initiates
regular impulses at a
fast rate. Each
impulse is conducted
normally to the
ventricles.

Sinus Tachycardia
 Regularity: Regular
 Rate: Greater than 100 beats per
minute (usually 100–160 beats per
minute)
 P Wave: Normal and upright; one P
wave in front of every QRS complex
 PRI: .12–.20 seconds and constant
 QRS: Less than .12 seconds

Sinus Arrhythmia
Sinus node fires faster
during inspiration and
slower during
expiration, creating
an irregular rhythm.
Rate is usually
normal. Conduction to
ventricles is normal.

Sinus Arrhythmia
 Regularity: Irregular
 Rate: 60–100 beats per minute
(usually)
 P Wave: Normal and upright; one P
wave in front of every QRS complex
 PRI: .12–.20 seconds and constant
 QRS: Less than .12 seconds
