CC1 Assignment 4
Sinus tachycardia can be caused by - ANS-Anxiety, fever, atropine
Syncope can be a manifestation of any tachycardia because - ANS-ventricular filling times are
shortened
Carotid sinus massage can lead to - ANS-sinus bradycardia, sinus block or sinus arrest
In atrial flutter - ANS-Atrial impulses are blocked by the AV node
The AR is always fast
The QRSs are normal as conduction beyond the AV node is not affected
The PR interval is not measurable as there are no P waves (replaced by flutter waves)
The initial energy level required to convert PAT is - ANS-50 joules
Junctional escape rhythm can deteriorate to - ANS-VT, junctional tachycardia and/or idiopathic
ventricular rhythm?
The distinguishable features of Wenckebach are - ANS-variable PR intervals, AR > VR
Multifocal PVCs are reflected as - ANS-different looking beats
A regular rhythm with an AR of 110, VR of 110, constant PR interval of 0.12 seconds, QRS
complexes of 0.08 seconds is - ANS-sinus tachycardia
The most distinguishable feature of atrial fibrillation is - ANS-an irregular rhythm
Lidocaine is often effective in treating ventricular rhythms because it - ANS-suppresses
ventricular irritability
A defibrillator should be quickly accessible for the patient in third degree AV block because this
block can deteriorate to - ANS-VT
Sinus arrest can be caused by - ANS-digoxin toxicity
PAT with an AR of 240 beats/minute would always have - ANS-equal AR and VR
an equal rhythm
P waves may not be visible is HR is too fast
if Ps not visible the PR interval can't be measured
