| Question | Answer |
|---|---|
| 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. |
