EKG Strips Images & Definitions
Atrial Flutter -has a "saw tooth or picket fence" atrial pattern (no P waves, F-waves instead 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:
- / 3
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.

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.
