Cardio Flashcards
1
Q
Recall diff types of arrthymias and their ECG patterns
A
- sinus rhythmia
- sinus arrhythmia
- supraventricular arrhythmia
- atrial fibrillation
- ventricular premature complex
- ventric arrhythmia
- ventricular tachy
- 1, 2, 3rd degree heart block
- L vs R bundle block
- sick sinus syndrome
2
Q
Tx for ventricular tachy
- immediate
- home
A
- lidocain IV
- sotalol +/- amiodarone, atenolol (no if CHF)
3
Q
Class I cardio drugs
- mech
- eg
A
- Na channel blockers
- lidocaine, mexiletine
4
Q
Class II cardio drugs
- mech
- use
- eg
- contraindication
A
- beta-blocker
- sympathetic excitement associated arrhythmias
- atenolol (B1)
- CHFm careful if resp
5
Q
Class III cardio drugs
- mech
- use
- eg
A
- K channel blocker
- ventric and supraventric arrhthmias
- sotalol (also B-blocker)
6
Q
Prefered drug for tx ARVC
A
Sotalol
7
Q
Amiodarone
- mech
- use
- side effects
A
- K and Na channel blocker, bit of B blocker and Ca channel blocker
- GI, liver, thyroid –> monitor BW
8
Q
Tx for supraventricular tachy
- hosp
- home
A
- IV diltiazem
- diltiazem
- sotalol, atenolol (no if CHF) if no cardio dz yet
9
Q
Class IV cardio drugs
- mech
- use
- eg
A
- Ca channel blocker –> slows conduction in AV node
- supraventricular tachy, A-fib
- diltiazem
10
Q
Digoxin
- mech
- use
- adverse effects
A
- parasympathomimetic (ie incr parasymp)
- tx a-fib
- GI, pro-arrhythmia
11
Q
Tx for bradyarrhythmia
A
- pacemaker
- anticholinergics (e.g. atropine) if high vagal tone is cause
- B agonists (e.g. terbutaline)
- theophylline (incr HR as side-effect)
12
Q
When to tx arrhythmia
A
- sign change in haemodynamics
- rapid HR
- R on T phenomion
- freq arrhythmia
