ECG Dysrhythmia Analysis: Rhythm Recognition (Relias)

ECG Dysrhythmia Analysis: Rhythm Recognition (Relias) How long is a normal QRS complex? *Ans*less than 0.12 seconds True or False: Multifocal Atrial Tachycardia is caused by at least three ectopic atrial pacemakers and has a rate of greater than 100 beats per minute. *Ans*True What ECG rhythm has no discernible P waves, irregular fibrillatory waves, and an irregular R to R interval? *Ans*Atrial fibrillation What helps determine if a patient is Â"toleratingÂ" a rhythm? *Ans*Blood pressure and level of consciousness What is a characteristic of sinus bradycardia? *Ans*less than 60 bpm What is a potential cause of PVCs? *Ans*Hypokalemia What is an expected atrial rate in atrial flutter? *Ans*250-400 bpm What is characteristic of standard ECG paper? *Ans*Comprised of small boxes measuring 0.04 seconds What is the normal duration for the PR interval? *Ans*0.12-0.20 What is the normal PR interval for an atrial fibrillation rhythm? *Ans*Not applicable What part of the cardiac cycle correlates with the QRS complex? *Ans*Ventricular depolarization What part of the heart ejects blood into the aorta? *Ans*Left Ventricle
