ACLS precourse self-assessment – Rhythms questions and answers well illustrated. Sinus Bradycardia - correct rate less than 50 bpm monomorphic ventricular tachycardia - correct answers.Ventricular tachycardia where the QRS complex has the same morphology or fixed shape. Supraventricular tachycardia (SVT) - correct answers.A faster than normal heart rate beginning above the heart's two lower chambers. Second degree AV block (Mobitz type 1) - correct answers.Wenckebach phenomenon, typically occurs at the AV node. Characterized by successive prolongation of the PR interval until an atrial impulse s not conducted to the ventricles. The P wave corresponding to the atrial impulse is not followed by QRS complex (P-R interval gets progressively longer). QRS complex drops. Atrial Fibrillation (A-Fib or AF) - correct "quiver" chaotically and the ventricles beat irregularly Sinus Tachycardia - correct answers.>100 (100-150) normal sinus rhythm; increased heart rate. Atrial Flutter - correct answers.Rapid, irregular atrial contractions due to an abnormality or atrial excitation. Stable tachycardia. (QRS < 0.12) narrow. Ventricular fibrillation (V-fib or VF) - correct rapid uncoordinated fluttering contractions of the ventricles. (pg. 116) Second Degree AV Block Mobitz Type 2 - correct answers.-PR interval is constant -atrial conduction to ventricle is intermittent (intermittent non-conduction of p waves with constant PR interval on conducted beats.
