BASIC DYSRHYTHMIA-RELIAS (ACTUAL 2025)
30 QUESTIONS WITH VERIFIED ANSWERS
Supraventricular Tachycardia (SVT) - <<<Answers>>an
abnormal heart rhythm arising from aberrant electrical activity
in the heart; originates at or above the AV node
First degree heart block - <<<Answers>>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) -
<<<Answers>>Progressively longer PR interval until the P
wave is not followed by a QPR
2nd Degree Heart Block (Mobitz II) - <<<Answers>>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
3rd degree heart block - <<<Answers>>no obvious
correlation between p and qrs, need pace maker
, premature ventricular contraction (PVC) - <<<Answers>>a
ventricular contraction preceding the normal impulse initiated
by the SA node (pacemaker)
Bigeminy PVC - <<<Answers>>every other beat is a PVC
PVC couplets - <<<Answers>>PVC occurring in pairs, no
adequate C.O. when this occurs
monomorphic ventricular tachycardia -
<<<Answers>>presents with wide QRS complexes of a
common shape.
Torsades de pointes - <<<Answers>>Rate: 120 - 200 usually
P wave: Obscured by ventricular waves
QRS: Wide QRS - "Twisting of the Points"
Conduction: Ventricular only
Rhythm: Slightly irregular
Ventricular fibrillation (V-fib) - <<<Answers>>abnormal
heart rhythm which results in quivering of ventricles
Idioventricular Rhythm - <<<Answers>><40
*looks like vtach but slow*
