One of the most common conversations I have in my office starts with a patient saying:
“I probably shouldn’t even be here. It’s just anxiety. I’m overreacting.”But here’s the truth: many people dismiss real heart symptoms as stress, anxiety, menopause, hot flashes, or thyroid issues. While those can certainly cause similar feelings, sometimes the real culprit is something much more serious—atrial fibrillation (AFib).
Why We Minimize Heart Symptoms
It’s natural to want to explain away uncomfortable sensations. Racing heart? Must be stress. Sweating? Probably hormones. Feeling lightheaded? Just exhaustion.
But in many cases, patients are actually experiencing AFib events—irregular heartbeats that increase stroke risk. These skipped or “funny beats” can cause anxiety, hot flashes, or feelings of stress, making it even harder to tell the difference.
How to Tell the Difference
The reality is, without checking your heart rhythm, there’s no way to be certain. That’s why I tell my patients:
- Don’t minimize symptoms. If something feels off, take it seriously.
- Use monitoring tools. Devices like KardiaMobile or an Apple Watch can quickly record your heart rhythm and help distinguish stress from AFib.
Get evaluated. Even if it turns out to be nothing, the peace of mind is worth it. If it is AFib, early detection can prevent serious complications like stroke.
When to Seek Help
If you experience:
- Fluttering, pounding, or irregular heartbeats
- Dizziness or lightheadedness
- Shortness of breath, fatigue, or unexplained weakness
- Episodes of “anxiety” that don’t quite add up
…it’s time to take a closer look.
The Bottom Line
Don’t brush off symptoms. What feels like stress, hormones, or anxiety could be your heart trying to get your attention. The best next step is to track your rhythm with a tool like KardiaMobile and bring the data to your cardiologist.
Early action can make the difference between reassurance and a life-threatening event.
