    What is the definition of Atrial Fibrillation?

    Atrial fibrillation (AF), also known as A-fib, is the most common type of irregular heartbeat (arrythmia) of the heart’s upper chambers (atria) which can lead to strokes, heart failure, blood clots in the heart and/or blockage of blood flow (ischemia) in the heart or other organs. Atrial fibrillation is frequently combined with a rapid heart rate (tachycardia) and occurs when the upper chambers of the heart (atria) receive abnormal electrical signals from the heart’s conduction system that causes the atria to quiver. Atrial fibrillation is categorized by the following four main types: Occasional (Paroxysmal) atrial fibrillation – This type of atrial fibrillation comes and goes, can last from minutes to hours, or even last as long as a week, or occur repeatedly, and may go away on its own. Persistent atrial fibrillation – In this type of atrial fibrillation, the irregular heart rhythm (arrythmia) doesn’t go away on its own and needs treatment to restore normal rhythm. Long-standing persistent atrial fibrillation – This type of atrial fibrillation occurs continuously, lasting longer than 12 months. Permanent atrial fibrillation – In this type of atrial fibrillation, the irregular heart rhythm cannot be restored to normal, in which case it becomes permanent, requiring heart medications and anticoagulants to prevent blood clots. Atrial fibrillation that occurs in individuals who do not have any heart defects or damage is called lone atrial fibrillation.

    When should I see an Atrial Fibrillation doctor in Portugal?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing an Atrial Fibrillation doctor in Portugal?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.

    How does MediFind rank Atrial Fibrillation doctors in Portugal?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Atrial Fibrillation doctors in Portugal?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with an Atrial Fibrillation doctor in Portugal?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Atrial Fibrillation doctor search results page. 

    Why is it important to get a second opinion from a different Atrial Fibrillation doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with an Atrial Fibrillation doctor in Portugal?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Atrial Fibrillation doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Atrial Fibrillation doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female Atrial Fibrillation doctors in Portugal?

    Look for the filter feature on the left side of the Atrial Fibrillation doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find an Atrial Fibrillation doctor that offers video calls?

    Look for the filter feature on the left-side of the Atrial Fibrillation doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
