What are the possible physiological mechanisms behind the changes observed? Does the intervention affect the patient’s quality of life or performance in activities of daily living?

Write the pathophysiology of atrial fibrillation, Hypercholesterolemia, and Hypertension.
For each topic I want:
• Description of the condition (the pathophysiology)
• possible causes
• incidence
• physical and/or physical and/or mental impairments and disabilities related to the condition.
• Details should be given on medical and exercise interventions.
• Provide a brief justification for the use of each intervention.
For this part: 3 pages divide it over atrial fibrillation and hypertension, and 1 page Hypercholesterolemia.

For the discussion discuss the potential/real beneficial effects of exercise intervention for each one atrial fibrillation, Hypercholesterolemia, and Hypertension:
• Which system (i.e. sensory, motor, cardiovascular, etc.) is improved after the intervention?
• What are the possible physiological mechanisms behind the changes observed?
• Are there scientific evidences to support the use of the chosen intervention?
• Does the intervention affect the patient’s quality of life or performance in activities of daily living?
For this part: divide it over 4 pages because for atrial fibrillation and Hypertension exercise intervention might be the same.
