, 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 ans:
Atrial Fibrillation-Has "chaotic" atrial electrical activity (no P waves, f-waves instead) with irregular R-R
intervals. - correct ans:
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 ans:
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 ans:
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 ans:
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 ans:
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 ans:
First Degree AV Block, the PR interval is constant and measures greater than 0.20 second. - correct ans:
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 ans:
Second Degree (AV) Block has a constant PR interval with blocked QRS complexes - correct ans:
Second Degree (AV) Block has a constant PR interval with blocked QRS complex (2) - correct ans:
