ECG 9 - Arrhythmias 3 Flashcards
1
Q
VF
- no ? and ECG totally disorganized
- patient usually will have ? ? ?
- manage as per ? ? protocol
A
qrs
LOC
cardiac arrest
2
Q
AF
- ? baseline with no ? waves
- ? is bombarded and will thus depol irregularly, leading to vent ? at an irregular ?
- usually 450-? atrial contractions per min
- normal ? as conduction from AVN is not abnormal
A
irregular p AVN contraction rate 600 qrs
3
Q
AF
- can be ?, or present with ?, palpitations, ?, ? pain or stroke/?
- if no ecg abnorms seen, ?h ? ecg monitoring or an ? recorder can be used to detect ? AF
A
aSx dyspnoea syncope chest TIA 24 ambulatory event paroxysmal
4
Q
AF Mx
- if presx ? with haemodynamic instability, do emergency ? without delaying for ?
- if hemodynamically stable, mx involves ? control, or ? control as well as ?
- ? control is generally first line
A
Sxatic cardioversion anticoag rate rhythm anticoag rate
5
Q
AF Mx
Rate control
-a bb (?) or ? (verapamil/diltiazem) are the agents used - what is CI in HF?
-the therapeutic target is ?-? bpm at rest
-if Sx not controlled with one drug - ? can be used - BB and ?
A
bisoprolol RLCCB RLCCB 60-80 combo digoxin
6
Q
AF Mx
Rhythm control (?)
-may be indicated in ? patients with ? onset AF (
A
cardioversion young new 48 reversible HF electrical flecanide, amiodarone
7
Q
AF Mx - Anticoag
- ? at initial presx, then assess need for long term anticoag using the ? score to assess ? risk
- anticoag considered in men with score of ? and anyone with score of ?
- the ? score can be used to assess the risk of a major ?
- target INR = ?-?
- either use ? or a ? - according to patient pref
- if anticoag CI - offer ? and ? - one ? agent is not enough
A
heparin cha2ds2vasc stroke 1 2 has bled bleed 2-3 warfarin NOAC aspirin clopidogrel anti-platelet
8
Q
AF- underlying causes
- cardiac - ?, ? heart disease, ? failure, and ? heart disease
- resp - ? infections, pulmonary ?, and lung ?
- systemic - XS ? intake, ?, ? depletion, infections, and ??
A
HTN
valvular
heart
ischaemic
chest
embolism
ca
alcohol
thyrotoxicosis
E-

9
Q
Atrial Flutter
if atrial rate is above ?/min and no flat ? between p waves exists, atrial flutter is present
–normally 300-? contractions /min
–classic ? ? baseline
-normal coordination of the ? are lost, but some element of ? still exists
-generally trtd as per ??
A
250 baseline 450 saw toothed atria synchronicity AF
