What is AF?
Atrial fibrillation (AF) is a supraventricular tachyarrhythmia resulting from irregular, disorganized electrical activity and ineffective contraction of the atria. The disorganised electrical impulses in that atria that causes them to fibrillate is usually at a rate of 300-600 bpm.
What are the three classifications for AF according to patterns of episodes?
What are non-cardiac causes of AF?
Non-cardiac conditions, such as:
○ Acute infection.
○ Autonomic neuronal dysfunction (such as vagally induced AF).
○ Electrolyte depletion (such as hypokalemia and hyponatremia).
○ Cancer (such as primary lung cancer involving the pleura and pericardium, and cancers such as breast cancer and malignant melanoma metastasising to the pericardium).
○ Pulmonary embolism.
○ Thyrotoxicosis
Diabetes mellitus
What are the symptoms for suspected AF in people with an irregular pulse with or without any of the following?
When should paroxysmal AF symptoms be suspected?
a. Less than 24 hours
b. Less than 48 hours
c. Less than 72 hours
Greater than 43 days
B . Suspect paroxysmal AF if symptoms are episodic and last less than 48 hours.
What is the two driving group entitlements that result in banning from driving if arrthymia hasn’t been controlled in X amount month/time?
- When is anticoagulant indicated in men and women WITH AF using X scoring system?
- What does the CHA2DS2VASc stand for and what are the scoring bands?
Congestive heart failure/left ventricular dysfunction (heart failure with reduced ejection fraction, or people with recent decompensated heart failure requiring hospitalization, irrespective of ejection fraction) = 1
What tool is used to measure bleeding risk to help guide decisions on anticoagulation?
ORBIT Score.
- What are is the range for patient with High ORBIT bleeding score risk?
A. 2.5-3.5
B. 4-6
C. 5-8
D. 4-7
D
In Ptx presenting with AF acutely w/o hemodynamic instability what should be offered in the first 48 hours?
When pharmacological cardioversion is agreed upon what is the first line agent used for Ptx with history of structural or ischemic heart disease presenting with new-onset AF?
Amiodarone
What does NICE guidance say about the treatment AF Ptx with cardioversion for whom the duration of arrythmia is greater than 48 hours or uncertain (hemodynamically stable) and is considered for long term RHYTHM control? ( do you cardiovert or not?)
In people with atrial fibrillation in whom the duration of the arrhythmia is greater than 48 hours or uncertain and considered for long‑term rhythm control, delay cardioversion until they have been maintained on therapeutic anticoagulation for a minimum of 3 weeks. During this period offer rate control as appropriate. [NICE 1.8.6]
What is first line anti-coagulant agent used in Ptx presenting with new-onset atrial fibrillation in whom a stable sinus rhythm has not been successfully restored within 48 hours of onset?
- If atrial fibrillation has been present for more than 48 hours and patient needs to be electrically cardioverted what is the next line of treatment in terms of anti-coagulation?
What is the first line therapy of choice in patients awaiting for cardioversion to maintain sinus rhythm? How long should they be continued on therapy?
