BASIC DYSRHYTHMIA RELIAS TEST
2024-2025 GRADED A+
2nd Degree Heart Block (Mobitz II) - ANS✔✔--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 - ANS✔✔--no obvious correlation between p and qrs, need
pace maker
premature ventricular contraction (PVC) - ANS✔✔--a ventricular contraction
preceding the normal impulse initiated by the SA node (pacemaker)
Bigeminy PVC - ANS✔✔--every other beat is a PVC
PVC couplets - ANS✔✔--PVC occurring in pairs, no adequate C.O. when this occurs
monomorphic ventricular tachycardia - ANS✔✔--presents with wide QRS complexes
of a common shape.
normal sinus rhythm - ANS✔✔--heart rhythm originating in the sinoatrial node with a
rate in patients at rest of 60 to 100 beats per minute
Sinus Arrhythmia - ANS✔✔--Appearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
Sinus Bradycardia - ANS✔✔--<60
normal sinus rhythm
Sinus Tachycardia - ANS✔✔-->100 (100-150)
normal sinus rhythm
Premature Atrial Contraction (PAC) - ANS✔✔--Heart Rate: Depends on underlying
rhythm
Regularity: Interrupts the regularity of underlying rhythm
P-Wave: can be flattened, notched, or unusual. May be hidden within the T wave
PRI: measures between .12-.20 seconds and can be prolonged; can be different from
other complexes
QRS: <.12 seconds
Sinus Arrest/Pause - ANS✔✔--- SA node doesn't fire
