StaRN EKG Test for HCA (Lethal and Non-Lethal Rhythms normal sinus rhythm - ANSWER HR 60-100 bpm Regular Sinus Bradycardia - ANSWER HR 60 bpm Regular Sinus Tachycardia - ANSWER HR 100 bpm Regular sinus dysrhythmia - ANSWER HR 60-100 bpm Irregular rhythm P waves normal QRS complexes normal PR Intervals normal Sinus Arrest - ANSWER HR 60-100 bpm Rhythm is irregular where there is a pause P waves, QRS complexes and PR intervals are normal and all look alike (but absent where there is a pause in rhythm) Wandering Atrial Pacemaker - ANSWER -HR 60-100 bpm -Slightly irregular -P waves differ, as frequently as from beat to beat, may be upright or inverted, can even be absent -QRS complexes normal, all appear the same -PR intervals vary, when the P wave is present the P'R intervals may be normal, shortened, or prolonged -QT intervals within normal range but may vary Premature Atrial Complexes - ANSWER -Rate depends on underlying rhythm -Irregular due to early beat -P' wave may be upright or inverted, will appear different than those of the underlying rhythm -QRS complexes are normal -PR intervals can be normal, shorter than 0.12 seconds in duration or prolonged -QT intervals within normal range but may be shortened Bigeminal Premature atrial complex - ANSWER Every other beat Trigeminal - ANSWER Every third beat Quadrigeminal - ANSWER Every fourth beat Atrial Tachycardia (SVT) - ANSWER -HR 150-250 bpm -Regular unless the onset is witnessed (thereby producing paroxysmal irregularity) -P' waves may be upright or inverted, will appear different than those of the underlying rhythm, can be hidden in the preceding T wave -QRS normal -PR intervals can be normal, shorter than 0.12 seconds in duration or unmeasurable if the P wave can't be distinguished from the preceding T wave Atrial Flutter - ANSWER -Ventricular rate may be slow, normal, or fast; atrial rate is between 250 and 350 beats per minute -May be regular or irregular -P waves absent, instead there are flutter waves -QRS complexes are normal -PR intervals unmeasurable Atrial Fibrillation (F waves) - ANSWER -Ventricular rate may be slow, normal, or fast; atrial rate is greater than 350 bpm -Totally irregular -P waves absent, instead there is a chaotic-looking baseline -PR intervals unmeasurable Premature Junctional Complex - ANSWER -Rate depends on underlying rhythm -Irregular due to early beat -Will be inverted-may precede, be buried in or follow the QRS complex -QRS complexes normal -PR intervals will be shorter than 0.12 seconds in duration Junctional Escape Rhythm - ANSWER -Rate 40 to 60 bpm -Regular -P' waves are inverted; may appear before, during, or after the QRS complex -QRS complexes are normal, all appear the same -(PR intervals) if present, the P'R intervals will be shorter than normal Accelerated Junctional Rhythm - ANSWER -Rate 60 to 100 bpm -Regular -P' waves are inverted; may appear before, during, or after the QRS complex -QRS complexes are normal & all appear the same -(PR intervals) if present, the P'R intervals will be shorter than normal Junctional Tachycardia - ANSWER -Rate 100 to 180 bpm -Regular -P' waves are inverted; may appear before, during, or after the QRS complex -QRS complexes are normal, all appear the same -(PR intervals) if present the P'R intervals will be shorter than normal Premature Ventricular Complexes - ANSWER -Rate depends on underlying rhythm -Irregular -P' waves are not visible as they are hidden in the QRS complexes -QRS complexes are wide and biz are in appearance, have T waves in the opposite direction of the R wave -(PR intervals) are absent Idioventricular Rhythm - ANSWER -Rate 20 to 40 bpm -Regular -P waves are not visible as they are hidden in the QRS complexes -QRS complexes are wide and bizarre in appearance, have T waves in the opposite direction of the R wave -(PR intervals) are absent Accelerated Idioventricular Rhythm - ANSWER -Rate 40 to 100 bpm -Regular -P waves are not visible as they are hidden in the QRS complexes -QRS complexes are wide and bizarre in appearance, have T waves in the opposite direction of the R wave -PR intervals absent Ventricular Tachycardia - ANSWER -Rate 100 to 250 bpm -Regular -P waves are not visible as they are hidden in the QRS complexes -QRS complexes are wide and bizarre in appearance, have T waves in the opposite direction of the R wave -(PR intervals) are absent Ventricular Fibrillation - ANSWER -Rate 300 to 500 ventricular unsynchronized impulses per minute -Totally chaotic -P waves absent -QRS complexes wavy, chaotic line without any logic -PR intervals absent Asystole - ANSWER Total absence of electrical activity 1st Degree AV Heart Block - ANSWER -(Rate) Underlying rate may be slow, normal, or fast -Underlying rhythm is usually regular -P waves present and normal and all are followed by a QRS complex -QRS complexes are normal -PR intervals longer than 0.20 seconds and constant 2nd Degree AV Heart Block, Type 1 - ANSWER -Ventricular rate may be slow, normal, or fast; atrial rate is within normal range -Patterned irregularity -P waves are present and normal; not all are followed by a QRS complex - QRS complexes are normal -PR intervals are progressively longer until a QRS complex is dropped, then cycle begins again 2nd Degree AV Heart Block, Type 2 - ANSWER -Ventricular rate may be slow, normal, or fast; atrial rate is within normal range -May be regular or irregular (depends on whether conduction ratio remains the same) -P waves are present and normal; not all P waves are followed by a QRS complex -QRS complexes should be normal -PR intervals constant for all conducted beats 3rd Degree AV Heart Block - ANSWER -Ventricular rate may be slow, normal, or fast; atrial rate is within normal range -Atrial rhythm and ventricular rhythms are regular but not related to one another -P waves are present and normal, not related to the QRS complexes; appear to march through the QRS complexes -QRS complexes are normal if escape focus is Junctional and widened is escape focus is ventricular -PR intervals are not measurable
