Understanding Atrial Fibrillation
Before discussing how devices like the Galaxy Watch can help detect AFib, it’s crucial to understand what AFib is and why it matters.
What is Atrial Fibrillation?
Atrial Fibrillation is a heart condition in which the upper chambers of the heart (the atria) experience chaotic electrical impulses, leading to an irregular and often rapid heart rate. This disarray can cause symptoms and complications, including:
- Heart Palpitations: An atypical awareness of heartbeats, which can feel racing or fluttering.
- Dizziness and Fatigue: These can occur due to inadequate blood flow to the body’s organs.
- Increased Risk of Stroke: The irregular blood flow can lead to blood clot formation, elevating the risk of stroke.
Symptoms and Risks
Despite being a serious condition, AFib may not always present clear symptoms. Many individuals might not even realize they have it, which underscores the importance of regular monitoring, especially for those with risk factors like:
- Age
- High blood pressure
- Heart disease
- A family history of AFib
