ECG Rhythms and other helpful tools Rhythm ECG Characteristics Strip Example 1. Normal sinus Rhytm (NSR)P Wave:YES PR Interval:0.12-0.20 sec QRS:0.06-0.10 sec Rate:60-100 bpm Regularity:Regular 2. Sinus Bradycardia Causes: Intrinsic sinus node disease Increased parasympathetic tone Drug effect P Wave:YES PR Interval:0.12-0.20 sec QRS:0.06-0.10 sec Rate:< 60 bpm Regularity:Regular 3. Sinus Tachycardia Causes: Exercise Hypovolemia Medications Feber Hypoxia Substances Anxiety, Fear Acute MI Fight or Flight Congestive Heart Failure P Wave:YES PR Interval:0.12-0.20 sec QRS:0.06-0.10 sec Rate:> 100 bpm Regularity:Regular

Rhythm ECG Characteristics Strip Example 4. SR wPACs (Premature atrial complexes) Causes: Normal Excessive use of caffeine, tobacco, or alcohol CHF Myocardial ischemia or injury Hypokalemia, Dig toxicity COPD P Wave:YES, early & upright, different from Sinus PR Interval:0.12-0.20 sec QRS:0.06-0.10 sec Rate:< 100 bpm dependent on underlying rhythm Regularity:irregular 5. SR wPVCs (Premature atrial complexes) Causes: Gastric overloadStressCaffeine, Alcohol, NicotineHeart DiseaseAcid-Base ImbalanceElectrolyte ImbalanceCyclic AntidepressantsHypoxiaAcidosisAcute MIP Wave:usually absent not present PR Interval:follows the underlying rhythm, but in the early complex no P wave is present QRS:0.06-0.10 sec underlying, with 0.12 sec or greater; bizarre and notched Rate:dependent on underlying rhythm Regularity:6. Atrial Fibrillation Causes: Ischemic heart disease Hypoxia Acute MI Digitalis toxicity Mitral or tricuspid disease P Wave:not identifiable PR Interval:not measurable QRS:0.06 – 0.10 sec Rate:Atrial: 400-700 bpm Ventricle: 160-180 bpm Regularity:irregular
