Final Exam Questions EKG Strips With 100% Correct Answers. Atrial Flutter -has a "saw tooth or picket fence" atrial pattern (no P waves, F-waves in stead that may be in a ratio) between the QRS complexes. - CORRECT ANSWER Atrial Fibrillation-Has "chaotic" atrial electrical activity (no P waves, f-waves instead) with irregular R-R intervals. - CORRECT ANSWER PJCs cause the rhythm to be irregular. The P wave is inverted if it can be seen. It may occur before, during or after the QRS. The P wave will not be seen due to its low voltage. - CORRECT ANSWER Junctional Rhythm may have an inverted or absent P wave. The P wave may occur before, during or after the QRS complex. The rate for this rhythm is 40-60 bpm. - CORRECT ANSWER Accelerated Junctional Rhythm may have an inverted or absent P wave. The P wave may occur before, during or after the QRS complex. The rate for this rhythm is 60-100 bpm. - CORRECT ANSWER Junctional Tachycardia Rhythm may have an inverted or absent P wave. The P wave may occur before, during or after the QRS complex. The rate for this rhythm is 100-180 bpm - CORRECT ANSWER Supraventricular Tachycardia presents with a "normal-narrow" appearing QRS complex and a rate of greater than 150 bpm. Remember for heart rates approaching 150 or higher, it will be very likely that the P wave will be buried. Be prepared to increase the paper speed for this rhythm. - CORRECT ANSWER First Degree AV Block, the PR interval is constant and measures greater than 0.20 second. - CORRECT ANSWER Second Degree AV Blocok Mobitz I (Wenkebach) has a cyclical prolonging PR interval until the QRS is dropped. Then the cycle begins again. ***Remember the clue "lengthen, lengthen drop Wenkebach. - CORRECT ANSWER
