What is the pathophysiology of atrial fibrillation?
What is the pathophysiology of atrial fibrillation?
- Prolonged QT interval on the ECG
- Regular and organized electrical activity in the atria
- Coordinated contraction of the atria
- Chaotic and disorganized electrical activity in the atria (correct)
What are some triggering factors for atrial fibrillation?
What are some triggering factors for atrial fibrillation?
- Low blood pressure, lung disease, anemia
- Hypertension, heart failure, coronary artery disease (correct)
- High cholesterol, diabetes, obesity
- Healthy lifestyle, regular exercise, balanced diet
What is a consequence of atrial fibrillation?
What is a consequence of atrial fibrillation?
- Regular ventricular response, leading to stable cardiac output
- Decreased risk of blood clot formation in the atria
- Irregular ventricular response, leading to variable cardiac output (correct)
- Consistently high heart rate
