Telemetry Test 49 Questions with Verified Answers Each small box on the monitoring EKG paper is how man seconds? - CORRECT ANSWER 0.04 seconds Paroxysmal means? - CORRECT ANSWER sudden onset and sudden termination Unique waveform characteristics of: Sinus Arrythmia - CORRECT ANSWER Regularly Irregular Sinus rhythm Unique waveform characteristics of: Atrial Fib - CORRECT ANSWER irregularly irregular with no p wave Unique waveform characteristics of: Atrial Flutter - CORRECT ANSWER prominent f waves/saw tooth pattern atrial kick is responsible for how much cardiac output? - CORRECT ANSWER 20-30% cardiac output PVC - CORRECT ANSWER premature ventricular contraction PAC - CORRECT ANSWER premature atrial contraction PJC - CORRECT ANSWER premature junctional contraction Unique waveform characteristics of: junctional complexes - CORRECT ANSWER may have no p waves, may have inverted or negative p waves, and have a PRI of <0.12 (short) Hallmark signs of a PVC - CORRECT ANSWER wide and bizarre QRS complex, originates in ventricle, and usually has a compensatory pause bigeminy - CORRECT ANSWER Ectopic beat every other beat trigeminy - CORRECT ANSWER ectopic beat every third beat quadgeminy - CORRECT ANSWER ectopic beat every fourth beat PVCs are frequently caused by what? - CORRECT ANSWER Hypokalemia aberrant/aberrancy refers to what - CORRECT ANSWER refers to abnormal conduction through the ventricles (cell to cell) resulting in wide complexes Unique waveform characteristics of: VTach - CORRECT ANSWER usually has a regular rhythm Which lead is best for measuring waveforms for rhythm interpretation? - CORRECT ANSWER Lead II Normal p waves - CORRECT ANSWER should be upright, best seen in Lead II truest picture of ventricular activity is in which lead - CORRECT ANSWER V lead Assessing new onset ST elevation - CORRECT ANSWER -presence of pain, SOB, or discomfort -check for lead placement accuracy -position patient in supine position with HOB up 30" and reassess ST -12 lead EKG and call MD SA Node rate - CORRECT ANSWER 60-100bpm AV node rate - CORRECT ANSWER 40-60bpm HIS-Purkinje system (ventricular) rate - CORRECT ANSWER 20-40bpm normal PR Interval - CORRECT ANSWER 0.12-0.20 sec normal QRS - CORRECT ANSWER 0.06-0.11 sec normal QTc - CORRECT ANSWER <0.50 sec prolonged QTc puts patient at risk for what? - CORRECT ANSWER R on T/Torsades de Pointe absolute refractory phase - CORRECT ANSWER when a cell is in this phase it cannot accept another impulse Main electrolytes of cardiac physiology - CORRECT ANSWER sodium and potassium (and Magnesium) Unique waveform characteristics of: Vfib - CORRECT ANSWER grossly irregular, ominous rhythm which produces no cardiac output treatment for vfib - CORRECT ANSWER defib Unique waveform characteristics of: Second Degree AV Block, Mobitz I (Wenkebach) - CORRECT ANSWER PRI progressively elongates until a ventricular complex is dropped Unique waveform characteristics of: Second degree AB block, Mobitz II (worse than Mobitz I) - CORRECT ANSWER PRI is constant, dropping QRS's at regular intervals; there are more p waves than QRS's Unique waveform characteristics of: Third Degree heart block - CORRECT ANSWER regular R-R, regular P-P, PRI's all different; atria and ventricles are beating totally independently If QRS is >0.12 sec and rate is 20-40bpm, the rhythm is most likely originating from? - CORRECT ANSWER originating from the ventricle Symptoms with arrythmias - CORRECT ANSWER dizziness, diaphoresis, SOB, hypotension, LOC Cariac output= - CORRECT ANSWER Heart rate x stroke volume Why is measuring QTc important? - CORRECT ANSWER B/c a prolonged QTc interval increases the risk of developing a lethal dysrhythmia ST segment may reflect myocardial injury or ischemia if? - CORRECT ANSWER it deviates from the isoelectric line and begins at the J point Junctional Escape Rhythm rate - CORRECT ANSWER 40-60 Accelerated Junctional Rate - CORRECT ANSWER 60-100 Junctional Tachycardia rate - CORRECT ANSWER >100 Unique waveform characteristics of: Idioventricular Rhythm - CORRECT ANSWER regular, HR 20-40bpm, wide and bizarre QRS failure to sense - CORRECT ANSWER pacer DOES NOT KNOW WHEN to spike/kick in, so spikes are in the wrong place failure to capture - CORRECT ANSWER pacer knows when to spike but NO QRS RESULTS failure to pace - CORRECT ANSWER no spike, no QRS; PACER DOES NOT FIRE AND NO BEAT Unique waveform characteristics of: Wandering atrial pacemaker - CORRECT ANSWER originating in multiple pacemakers and can be slightly irregular; usually 60-100bpm; p wave morphology changes beat to beat; PRI and QRS WDL Unique waveform characteristics of: SVT - CORRECT ANSWER tachycardia originating above the ventricle; generally 150-250bpm; can't see p or t waves to measure
