RELIAS DYSRHYTHMIA BASICS EXAM QUESTIONS WITH ANSWERS normal sinus rhythm (NSR) Criteria: (PR, QRS, QT, Rhythm: reg or irreg) 1 P-wave for Every QRS, REGULAR rhythm PR: 0.12-0.20 QRS: 0.06-0.10 BBB = 0.12 QT: 0.36-0.44 BPM: 60-100 Sinus Bradycardia Criteria: (PR, QRS, QT, Rhythm: reg/irreg) PR: 0.12-0.20 QRS: 0.06-0.10 QT: 0.36-0.44 BPM: 60 (Reg. rate) Tx: Atropine 0.5mg, Pace, Dopamine 2-10 mcg/kg/min, Epie 2-10 mcg/min Sinus Tachycardia Criteria: (PR, QRS, QT, Rhythm: reg/irreg) PR: 0.12-0.20 QRS: 0.06-0.10 QT: 0.36-0.44 BPM: 100-150 (Reg. rate, P wave may merge with T-wave) Cause: fear, anxiety, hypoxia, sepsis, hypovolemia, infection Sinus Arrhythmia Criteria: (PR, QRS, QT, Rhythm: reg/irreg) PR: 0.12-0.20 QRS: 0.06-0.10 QT: 0.36-0.44 BPM: HR increase w/ inspiration, HR decrease w/expiration P-P interval lengthen and shorten with respirations Irreg Rhythm NO TX Sinus Pause Criteria: (PR, QRS, QT, Rhythm) PR: 0.12-0.20 QRS: 0.06-0.10 QT: 0.36-0.44 Irregular rhythm Short Pause: no TX; Long/Freq. Pause & symptomatic = TX like Sinus Brady Premature Atrial Contraction (PAC) Heart Rate: Depends on underlying rhythm Regularity: Interrupts the regularity of underlying rhythm P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave PRI: measures between .12-.20 seconds and can be prolonged; can be different from other complexes QRS: .12 seconds TX: none, check Lytes, precursor for A-Fib/Flutter Atrial Fibrillation (A-Fib) (PR, QRS, QT, RHYTHM, TX) PR: Can't Measure NO P WAVE QRS: 0.06-0.10 QT: May/May Not be Measurable Rhythm: IRREGULARLY IRREGULAR Rate: Atrial 400 BPM Tx: Diltiazem (Cardizem), Amiodarone, Beta Blocker (Lopressor), Digoxin, Anti-Coag (Heparin), Cardiovert Atrial Flutter (PR, QRS, QT, RHYTHM, TX) PR: Can't Measure NO P WAVE QRS: 0.06-0.10 QT: Can't Measure Rhythm: Ventricular Rate = Reg. Atrial = Irreg Atrial Rate 250-400 Ventricular: count QRS "Saw Tooth/Flutter Waves" Tx: Same as A-Fib paroxysmal atrial tachycardia (PAT) (PR, QRS, QT, RHYTHM, TX) an episode that begins and ends abruptly during which there are very rapid and regular heartbeats that originate in the atrium PR: 0.12-0.20 QRS: 0.06-0.10 QT: 0.36-0.44 Atrial Rate: 150-250 Reg Vent Rate: 150-250 Tx: Adenosine, Diltiazem, vagal, Cardiovert Premature Junctional Contraction (PJC) (PR, QRS, QT, RHYTHM, TX) Rate: Normal or accelerated 60-100 P wave: Inverted Before/After QRS, Absent PR: 0.12-0.20 QRS: normal 0.06-0.10 QT: 0.36-0.44 Conduction: normal rhythm: irregular: PICs occur early in cycle of baseline rhythm NO TX: check E-Lytes -an ectopic pacemaker in the AV Junction produces PJC's Junctional Rhythm (PR, QRS, QT, RHYTHM, TX) Rate: Atrial 40-60, Ven. 40-60, Regular P-Wave: Inverted, Before/After QRS, Absent PR: 0.12 (May not be able to if Absent) (May be 0.12 if before QRS) QRS: 0.06-0.10 QT: 0.36-0.44 Tx: If symptomatic Atropine, Pacemaker Accelerated Junctional Rhythm (PR, QRS, QT, RHYTHM, TX) Rhythm: Regular regular rhythm Rate 60-100 P-waves = inverted or occur before during or after QRS, PRI measured if p before QRS 0.12 PR: 0.12 (May not be able to if absent/ may be 0.12 if before QRS) QRS: 0.06-0.10 QT: 0.36-0.44 Tx: None Upgrade to remove ads Only $35.99/year Junctional Tachycardia (PR, QTS, QT, RHYTHM, TX)
