CVS - arrhythmia Flashcards
1
Q
conduction system
A
SA -> AV -> bundle of His
2
Q
reasons for slow conduction
A
- heart block: interrupted conduction from atrium -> ventricle
- impulse generation
3
Q
reasons for fast conduction
A
- abnormal automaticity
- triggered activity: ectopy
- disorganisation: atrial/ventricular fib
4
Q
bradycardia symptoms (3)
A
- lethargy
- giddiness (CO decrease)
- dyspnea
5
Q
bradycardia treatment
A
atropine: increase HR (temp)
pacemaker
6
Q
tachycardia symptoms (4)
A
- palpitations
- giddiness (CO decrease cause the decrease in SV is > increase in HR)
- syncope (passing out)
- cardiac arrest
7
Q
tachycardia treatment
A
- defibrillators
- electrophysiology
