Telemetry monitoring Exam 29 Questions with Verified Answers Aberrant ventricular conduction - CORRECT ANSWER conduction of an impulse NOT by the normal ventricular system but either through the ca... rdiac muscle itself or through extra conduction pathways. accelerated escape rhythm - CORRECT ANSWER occurs when a lower pacemaker initiates impulses at a rate faster than its inherent rate. AV dissociation - CORRECT ANSWER the atria and ventricles are being paced independently. bigeminy - CORRECT ANSWER pairs of beats, most often a sinus beat with an early impulse. Most often refers to a PVC every other beat, but can also be a PAC or PJC. asystole - CORRECT ANSWER the heart has lost its electrical activity, and there is no electrical pacemaker to initiate electrical flow. idioventricular rhythm - CORRECT ANSWER in the absence of a higher pacemaker, the VENTRICLES initiate a regular impulse at their inherent rate of 20-40 bpm. ventricular fibrillation - CORRECT ANSWER ventricles become irritable and generate incoordinated, chaotic impulses that cause the heart to fibrillate rather than contract ventricular tachycardia - CORRECT ANSWER an irritable focus in the VENTRICLES fires regularly at a rate of 150-250 bpm premature ventricular contractions (PVC) - CORRECT ANSWER single irritable focus within the ventricles that fires prematurely to initiate an ectopic complex. complete heart block; third degree heart block - CORRECT ANSWER the atria and the ventricles function in a totally disassociated fashion wenckebach; mobitz I - CORRECT ANSWER impulses from the sinus node are delayed in the AV node a little longer than the proceeding one, until one is eventually blocked completely. classical second degree block; mobitz II - CORRECT ANSWER the AV node selectively conducts some beats while blocking others. (Causing more P waves than QRS complexes.) first degree heart block - CORRECT ANSWER the AV node holds each sinus impulse longer than normal before conducting it through the ventricles. (Prolonged PRI) junctional escape - CORRECT ANSWER regular rhythm, 40-60 bpm, p waves before or after QRS, or lost entirely within the QRS, and if visible will be inverted. PRI less than .12 seconds (if p is visible), and the QRS will measure less than .12 seconds. accelerated junctional rhythm - CORRECT ANSWER Regular rhythm 60-100 bpm P wave, if visible will be inverted, may be lost in the QRS or occur after QRS PRI, if P is visible, will be < .12 seconds QRS < .12 seconds junctional tachycardia - CORRECT ANSWER Regular rhythm 100-180 bpm PRI, if P is visible will be inverted, P may be lost in the QRS or occur after QRS PRI, if P is visible, < .12 seconds QRS < .12 seconds Premature Junctional Contraction (PJC) - CORRECT ANSWER single early beat, with inverted P wave, or not visible P wave, or P wave after QRS, if visible, P wave will be inverted and have a PRI<.12 seconds Atrial flutter - CORRECT ANSWER atrial rhythm is regular atrial rate 250-350 bpm P waves have sawtooth appearance cannot measure PRI ORS measures <.12 seconds atrial fibrillation - CORRECT ANSWER Irregular No P wave QRS <.12 seconds Rate up to 100 bpm atrial tachycardia - CORRECT ANSWER Regular Rate 150-250 bpm P waves-yes, but may be lost in high rate PRI between .12-.20 seconds QRS < .12 seconds Premature atrial contraction (PAC) - CORRECT ANSWER Single premature ectopic beat from the Atrium Wandering pacemaker - CORRECT ANSWER Each beat originates from a different focus. Morphology of P waves changes as pacemaker site changes. Rate 60-100 bpm sinus arrhythmia - CORRECT ANSWER Rate 60-100 bpm uniform P waves PRI between .12 and .20 seconds QRS <.12 seconds R-R intervals vary, irregular sinus tachycardia - CORRECT ANSWER Regular uniform P waves PRI between .12 and .20 seconds QRS <.12 seconds Rate 100-160 bpm sinus bradycardia - CORRECT ANSWER regular uniform P waves PRI between .12 and .20 seconds QRS <.12 seconds Rate <60 bpm Normal sinus rhythm - CORRECT ANSWER regular uniform P waves PRI between .12 and .20 seconds QRS <.12 seconds Rate 60-100 bpm P wave - CORRECT ANSWER Atrial depolarization, normal measurement .12-.20 seconds QRS complex - CORRECT ANSWER ventricular depolarization, normal measurement <.12 seconds T wave - CORRECT ANSWER ventricular repolarization [Show More]
