Atrial fibrillation is a common arrhythmia in which the upper chambers of the heart are activated irregularly. It may cause palpitations or no symptoms at all. Care focuses on four goals: managing associated factors, preventing blood clots, rhythm or rate control, and regular reassessment.
At a glance
The main points
- Diagnosis needs heart rate recording, not just smartwatch reading.
- Stroke risk is assessed individually and changes over time.
- Rate control and rhythm control are different treatment approaches.
- Blood pressure, weight, sleep apnoea, alcohol and exercise all affect the course of the condition.
How is the diagnosis confirmed?
Suspicion can be triggered by a palpitation, an irregular pulse, or a mobile device alert. Diagnosis requires electrocardiographic documentation and medical interpretation. If the episode is intermittent, a Holter or longer recording may be required.
Then the duration and frequency of the episodes, possible triggering factors, accompanying diseases and the structure of the heart are evaluated. The same arrhythmia name does not mean the same plan for everyone.
Why stroke risk is assessed
Dysfunction of the sinuses can favor the formation of a blood clot, which in some cases can cause a stroke. The risk is not the same for everyone and is estimated by factors such as age, hypertension, diabetes, heart failure, vascular disease and previous stroke.
When anticoagulation is indicated, the goal is to reduce the risk of thrombosis. The decision, choice of drug, and dose need individualization and review. It is not interrupted because the rhythm "seems good" without a medical order.
Rate control and rhythm control
Rate control aims to keep the heart rate within an appropriate range, even if the arrhythmia continues. Rhythm control aims to restore and maintain sinus rhythm using medication, electrical cardioversion or ablation in suitable patients.
The choice depends on the symptoms, the duration of the arrhythmia, the age, the structure of the heart, other conditions and the patient's preferences. Often the plan is adjusted as the situation changes.
Care beyond arrhythmia
Proper blood pressure regulation, management of heart failure or diabetes, healthy weight, investigation of possible sleep apnea, and limiting excess alcohol are essential parts of treatment. It's not just general wellness advice.
Regular exercise adapted to your needs is usually beneficial, but the appropriate intensity depends on your symptoms, heart rhythm and overall condition.
What is monitored along the way
Symptoms, pulse and blood pressure where appropriate, bleeding episodes if taking anticoagulant, kidney function for certain medications and changes in risk factors are recorded. Absence of symptoms does not always mean absence of episodes.
Thromboembolic risk is dynamic: a new age group or a new disease can change the decision. That's why reappraisal is part of healing, not a sign of failure.
Practical in everyday life
Keep an up-to-date medication list and tell doctors and dentists if you are taking an anticoagulant. Don't take anti-inflammatories or supplements without checking for potential interactions. If bleeding occurs, seek instructions based on severity.
Smartwatch or blood pressure monitor can provide useful information, but notifications need confirmation. Save the file and note symptoms and time.
When not to wait
Immediate medical attention
Call 112 or 166 immediately for a new neurological symptom (weakness, facial drooping or difficulty speaking), fainting, severe shortness of breath or persistent chest pain. A very fast heartbeat with a strong feeling of being unwell needs urgent assessment.
