BASIC DYSRHYTHMIA-RELIAS EXAM 2025
QUESTIONS AND ANSWERS.
Supraventricular Tachycardia (SVT) - correct answer - an
abnormal heart rhythm arising from aberrant electrical activity in
the heart; originates at or above the AV node
First degree heart block - correct answer - atrioventricular (AV)
block in which the atrial electrical impulses are delayed by a
fraction of a second before being conducted to the ventricles
2nd degree heart block type 1 (Wenkebach) - correct answer -
Progressively longer PR interval until the P wave is not followed
by a QPR
2nd Degree Heart Block (Mobitz II) - correct answer - Rare, but
more serious
Sudden appearance of a nonconducted P-wave
P-waves are nl, but some aren't followed by a QRS complex
PR & RR intervals are constant
, Page | 2
3rd degree heart block - correct answer - no obvious correlation
between p and qrs, need pace maker
Premature ventricular contraction (PVC) - correct answer - a
ventricular contraction preceding the normal impulse initiated by
the SA node (pacemaker)
Bigeminy PVC - correct answer - every other beat is a PVC
PVC couplets - correct answer - PVC occurring in pairs, no
adequate C.O. when this occurs
Monomorphic ventricular tachycardia - correct answer - presents
with wide QRS complexes of a common shape.
Torsades de pointes - correct answer - Rate: 120 - 200 usually
P wave: Obscured by ventricular waves
QRS: Wide QRS - "Twisting of the Points"
Conduction: Ventricular only
