Relias Dysrhythmia Basic A

Normal sinus rhythm - Regular Rate: 60-100 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Bradycardia - Regular Rate: <60 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Tachycardia - Regular Rate: 100-150 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Premature Atrial Contraction - IRREGULAR Rate: depends on underlying rhythm P wave: Present or hidden in T wave PR Interval: 0.12-0.20 sec QRS: <0.12 sec Atrial Fibrillation - IRREGULAR Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: <0.12 sec A fib RVR - IRREGULAR Ventricular rate: 100-175 P wave: unable to see PR Interval: N/A QRS <0.12 sec Atrial Flutter - Usually REGULAR can be irregular Atrial rate: 250-350 Ventricular rate: variable BUT < atrial rate P Wave: Flutter PR Interval: N/A QRS: <0.12 sec Supraventricular Tachycardia - Regular Rate: 150-350 P wave: Hidden in QRS or T wave PR: unable to determine QRS: <0.12 sec Junctional Rhythm - Regular Rate: 40-60 P Wave: ABSENT or INVERTED PR Interval: None or <0.12 QRS: <0.12 sec Accelerated Junctional Rhythm - Regular Rate: 60-100 P Wave: NONE or INVERTED PR Interval: None or <0.12 QRS: <0.12 sec Junctional Tachycardia - Regular Rate: >100 P Wave: NONE or INVERTED PR Interval: None or <0.12 QRS: <0.12 sec
