CSCT EXAM PREP
1. Multifocal Atrial Tachycardia


Answer -HR>100bpm (usually 100-150bpm; may be as high as 250bpm)


-Irregularly irregular rhythm w/ varying PP, PR, RR intervals


-3 distinct P-wave morphologies in the same lead


-Isoelectric baseline b/w P-waves (no flutter waves)


-not just a sinus rhythm w/ frequent PACs


2. Paroxysmal Atrial Tachycardia


Answer -atrial tachycardia that begins & ends abruptly


-P wave abnormal in comparison to sinus P wave


-atrial rate >100bpm


-3 consecutive identical ectopic p waves

,-QRS usually normal unless pre-existing bundle branch


-isoelectric baseline


3. Premature Atrial Complex (PAC)


Answer -abnormal (non-sinus) P wave is followed by a QRS complex


-can hide in preceding T wave


4. Atrial Fibrillation


Answer -irregularly irregular rhythm


-no P waves


-absence of an isoelectric baseline


-variable ventricular rate


-QRS complexes usually <120ms


-coarse or fine fibrillary waves


5. Atrial Flutter

, Answer -narrow complex tachycardia


-regular atrial activity at ~300bpm


-flutter waves (saw-tooth) best seen in leads II, III, aVF


-loss of isoelectric baseline


6. Ashman's Phenomenon


Answer -type of beat w/ a wide QRS complex, typically mimicking RBBB


-typically appears during atrial fibrillation


-often mistaken for PVCs


-follow a short R-R interval and are preceded by a long R-R interval


-aberrantly conducted complex that originates above the AV node rather than originating in the right or left ventricle
