Cardiac Strips

Types of cardiac problems shown on strips.

Normal Sinus Rhythm Rhythm: Regular Rate: 60-100 P wave: Present PR: 0.12-0.20 QRS: 0.04-0.10 Everything is normal.
Sinus Dysrhythmia Rhythm: Irregular Rate: 60-100 P-wave: Present PR: 0.12-0.20 QRS: 0.04-0.10 Everything is normal except the rhythm.
Sinus Bradycardia Rhythm: Regular Rate: <60 P-wave: Present PR: 0.12-0.20 QRS: 0.04-0.10 Everything normal but rate is slow
Sinus Tachycardia Rhythm: Regular Rate: >100 P-Wave:Present PR: 0.12-0.20 QRS: 0.04-0.10 Everything is normal but rate is fast.
Premature Atrial Contraction (PAC) Rhythm: Irregular Rate: varies P-wave: Premature, abnormal shape PR: Normal QRS: Usually normal Premature P-wave with a narrow QRS. P-wave may be hidden in T-wave.
Paroxysmal Atrial Tachycardia (PAT) Rhythm: Regular Rate: 150-250 P-wave: not visible PR: unmeasurable QRS: narrow No visible P-wave because of the fast rate.
Atrial Flutter Rhythm: Regular Rate: 250-400, extremely fast P-wave: Abnormal PR: unmeasurable QRS: usually normal This strip's p-wave has a sawtooth appearance. Think of a butterfly fluttering it's wings.
Atrial Fibrillation (A-Fib) Rhythm: Irregularly irregular Rate:extremely fast, above 400 P-wave: absent PR:unmeasurable QRS:usually normal No visible P-wave.
1st Degree AV Block Rhythm: Regular Rate: Normal or bradycardia P-wave: normal PR: Prolonged QRS: Normal Everything is normal except for the prolonged PR interval.
2nd Degree AV Block Type I (Wenchebach or Mobitz I) Rhythm: Irregular Rate: normal or slow P-wave: present but too many PR: gets progressively longer QRS:normal This is recognized by P-waves with no QRS. The PR interval repeats it's self.
2nd Degree AV Block Type II Rhythm: Regular Rate: Slow P-wave: present, too many PR: normal or prolonged QRS: Wide P-waves with out QRS. Pattern does not repeat.
3rd Degree AV Block (Total Heart Block) Rhythm:Regular Rate: normal or slow P-wave: present but may be buried in the QRS PR: unmeasurable QRS: Long, wide The space between R-R will be the same, as will P-P. No pattern
Premature Junctional Contractions (PJC) Rhythm: Irregular when PJC occur Rate: P-wave: inverted or absent PR: Shortened QRS:Normal P-wave may occur before, during or after QRS. May also be absent or inverted.
Paroxysmal Junctional Tachycardia Rhythm: Regular Rate: 150+ P-wave: None PR: None QRS:Normal This is a cluster of 3 or more PJC. Same rules as PJC
Junctional Escape Rhythm: Irregular Rate: P-wave: PR: QRS: normal This has periods of flat line.
Premature Ventricular Contraction (PVC) Rhythm: Regular or Irregular Rate: Fast P-wave: Hidden PR: none QRS: Wide Premature, wide complex no proceeding P-wave.
Ventricular Tachycardia (V-Tach) Rhythm: Regular Rate: Fast P-wave: Usually not visible PR: unmeasurable QRS: Wide and distorted Wide complex, over 0.12, no visible P-wave, complexes look like PVC.
Ventricular Fibrillation (V-Fib) Rhythm: irregular Rate: ? P-Wave: none PR: None QRS: None This is a squiggly line on the strip. Can be a fine or course line. Usually follows R on T.
Idioventricular Rhythm (Dying Heart) Rhythm: Regular Rate: slow, and slowing This is a patient heart that is slowing to stop. CPR required if no DNR
Asystole Flat line, no beating heart.
