    • Atrial flutter
    • Rhythm: Regular or irregular
    • Rate: Fast (250-350 bpm) for Atrial, but ventricular rate is often slower
    • P Wave:Not observable, but saw-toothed flutter waves are present
    • PR Interval: Not measureable
    • QRS: Normal (0.06-0.10 sec)
    • Normal Sinus Rhythm
    • Rhythm: Regular
    • Rate: Normal (60-100 bpm)
    • P Wave: Normal (positive & precedes each QRS)
    • PR Interval: Normal (0.12-0.20 sec)
    • QRS: Normal (0.06-0.10 sec)
    • First degree heart block
    • PR interval: .20<
    • Atrial Fibrillation
    • Rhythm: Irregular
    • Rate: Very fast (> 350 bpm)
    • P Wave: Absent - erratic waves are present
    • PR Interval: Absent
    • QRS: Normal
    • Idioventricular Rhythm
    • Rhythm: Regular
    • Rate: Slow (20-40 bpm)
    • P Wave: Absent
    • PR Interval: Not measurable
    • QRS: Wide (>0.10 sec), bizarre appearance
    • Junctional Escape Rhythm
    • Rhythm: Regular
    • Rate: Slow (40-60 bpm)
    • P Wave: Present before, during (hidden) or after QRS, if visible it is inverted
    • PR Interval: Not measurable
    • QRS: Normal (0.06-0.10 sec)
    • Second Degree Heart Block Type II
    • Rhythm: Regular (atrial) and irregular (ventricular)
    • Rate: Characterized by Atrial rate usually faster than ventricular rate (usually slow)
    • P Wave: Normal form, but more P waves than QRS complexes
    • PR Interval: Normal or prolonged
    • QRS: Normal or wide
    • Sinus Arrest
    • Rhythm: Irregular due to pause
    • Third degree heart block
    • Rhythm: Regular, but atrial and ventricular rhythms are independent
    • Rate: Atrial rate usually normal and faster than ventricular rate
    • P Wave: Normal shape and size, may appear within QRS complexes
    • PR Interval: Absent: the atria and ventricles beat independently.
    • QRS: Normal, but wide if junctional escape focus
    • Accelerated Idioventricular Rhythm
    • Rhythm:┬áRegular
    • Rate: 50-110 bpm
    • P Wave: Absent
    • PR Interval: Not measurable
    • QRS: Wide (>0.10 sec), bizarre looking
    • Ventricular Tachycardia┬áTorsade de Pointes
    • Rhythm: Irregular
    • Rate: Fast (200-250 bpm)
    • P Wave: Absent
    • PR Interval: Not measurable
    • QRS: Wide (>0.10 sec), bizarre looking
    • Supraventricular Tachycardia
    • Rhythm: Regular
    • Rate: Fast (150-250 bpm)
    • P Wave: Merged with T wave
    • PR Interval: Normal (0.12 sec)
    • QRS: Normal (.10 sec)
    • Sinus Tachycardia
    • Rhythm: Regular
    • Rate: Fast (> 100 bpm)
    • P Wave: Normal, may merge with T wave at very fast rates
    • PR Interval: Normal (0.12-0.20 sec)
    • QRS: Normal (0.06-0.10 sec)
    • Notes: QT interval shortens with increasing heart rate
    • Ventricular Tachycardia (Monomorphic)
    • Rhythm: Regular
    • Rate: Fast (100-250 bpm)
    • P Wave: Absent
    • PR Interval: Not measurable
    • QRS: Wide (>0.10 sec), bizarre looking
    • Premature Ventricular Contraction
    • Rhythm: Irregular
    • Rate: The underlying rate
    • P Wave: Absent
    • PR Interval: Not measurable
    • QRS: Wide (> 0.10 sec), bizarre appearance
    • Notes: Two PVCs together are termed a couplet while three PVCs in a row with a fast rhythm is ventricular tachycardia
    • Pacemaker Failure to Capture
    • Rhythm: Irregular
    • Rate: Slow or normal
    • Notes: Pacemaker spikes are not followed by P waves or QRS complexes
    • Sinus Brady with frequent (bigeminal)PVC's
    • QRS: Wide (> 0.10 sec), bizarre appearance
    • Notes: PVC appears every second beat
    • Multifocal Atrial Tachycardia
    • Rhythm: Irregular
    • Rate: Fast (> 100 bpm)
    • P Wave: Often changing shape and size from beat to beat (at least three differing forms)
    • PR Interval: Variable
    • QRS:n Normal (0.06-0.10 sec)
    • Notes: T wave is often distorted Also review wandering atrial pacemaker lesson
