Clinical Management of Atrial Fibrillation Flashcards
1
Q
Arrhythmia
A
- Abnormal rate or rhythm of heat rate
- Patient >65 or those with hypertension risk
2
Q
Measure pulse
A
- Measure 30s of heart rate by radial pulse multiply by 2
- Check regularity
3
Q
ECG
A
- Standard electrogram
- P wave shows that AV node is working properly
- QRS complex which is the depolarization
- T wave shows repolarization
4
Q
What happens happens to ECG at AF
A
- SA node fire multiple times
- May start in the atrium or anywhere else
- AV node ignore and regulate
- P wave disappear
5
Q
Ectopic beats
A
- Common and harmless
6
Q
Arterial fibrillation
A
- Common to sustain normal heart rate and rhythm
- Irregular complex of beats no P wave
7
Q
Ventricular tachycardia
A
- Regular but fast heart rate
8
Q
Ventricular fibrillation
A
- Most common life threatening arrhythmias
9
Q
Paroxysmal AF
A
- Episodes come and go stop within 48hrs of any treatment
10
Q
Persistent AF
A
- Each episode longer than seven days
11
Q
Long standing persistent AF
A
- Consistent AF for a yr or longer
12
Q
Permeant AF
A
- Present for a long time
13
Q
Symptoms of AF
A
- Asymptomatic in older people
- Palpitations
- Tiredness
- Dizziness
- Chest pains
14
Q
AF prognosis
A
- Common in older people >65 women
- Most like with people that have hypertension or atherosclerosis
- Good with treatment not life threatening
- Heart failure ventricles work too hard possible stroke
15
Q
Goals of management
A
- Establish diagnosis
- Control and prevent symptoms so stroke can be prevented
16
Q
Ambulatory ECG
A
- Paroxysmal AF portable therefore can detect the arrythmias worn for a week
