HEART FAILURE WITH ATRIAL
FIBRILLATION MIDTERM STUDY SHEET
2026 QUESTIONS WITH ANSWERS GRADED
A+
●● What are the two main types of atrial fibrillation based on duration?
Answer: Paroxysmal (less than 7 days) and persistent (more than 7
days).
●● What can happen due to turbulent blood flow in atrial fibrillation?
Answer: Formation of a thrombus that can dislodge and cause a stroke.
●● What are common causes of atrial fibrillation?
Answer: Advanced age, congenital heart disease, hypertension, and
endocrine disorders.
●● What is the estimated prevalence of atrial fibrillation in individuals
over 75?
Answer: Approximately 9%.
●● What is the lifetime risk of developing atrial fibrillation by age 80?
Answer: 22%.
,●● What are the three patterns of atrial fibrillation?
Answer: Paroxysmal, persistent, and permanent.
●● What characterizes paroxysmal atrial fibrillation?
Answer: Recurrent episodes that terminate spontaneously within seven
days.
●● What is persistent atrial fibrillation?
Answer: Atrial fibrillation that lasts more than seven days and requires
intervention.
●● What is long-standing persistent atrial fibrillation?
Answer: Atrial fibrillation present for more than 12 months.
●● What defines permanent atrial fibrillation?
Answer: A decision to stop all therapies due to unresponsive rhythm.
●● What role does cardiac remodeling play in atrial fibrillation?
Answer: It causes structural and electrical changes leading to deranged
rhythm.
●● What is the most common initiating trigger for atrial fibrillation?
,Answer: Ectopic focus in the atria, often around the pulmonary veins.
●● What are common symptoms of atrial fibrillation?
Answer: Palpitations, chest pain, shortness of breath, and dizziness.
●● What is the initial evaluation for a patient with atrial fibrillation?
Answer: Assessment for hemodynamic instability and history of
symptoms.
●● What physical exam findings may indicate atrial fibrillation?
Answer: Tachycardia, irregularly irregular pulse, and signs of heart
failure.
●● What is the significance of ECG in atrial fibrillation?
Answer: It is critical for diagnosing atrial fibrillation.
●● What are potential complications of atrial fibrillation?
Answer: Cardiogenic shock and ischemic stroke.
●● What lifestyle factors may contribute to atrial fibrillation?
Answer: Increased alcohol consumption, smoking, and illicit drug use.
, ●● What is the relationship between age and atrial fibrillation
prevalence?
Answer: Prevalence increases with age, particularly in those over 75.
●● What is the role of inflammation in atrial fibrillation?
Answer: Conditions causing inflammation can lead to the development
of atrial fibrillation.
●● What are some neurological disorders associated with atrial
fibrillation?
Answer: Subarachnoid hemorrhage and stroke.
●● What is the impact of hypertension on atrial fibrillation?
Answer: It is a common cause that can lead to paroxysmal and persistent
forms.
●● What is the importance of a complete history in atrial fibrillation
diagnosis?
Answer: It helps identify risk factors and symptoms relevant to the
condition.
●● What findings may indicate carotid artery disease during a physical
exam?
