Is it normal for AFib to feel like a blow to the chest?

Question

Hello doctor,

I am 31 and was recently diagnosed with atrial fibrillation (AFib). During episodes, it sometimes feels like a sudden thump or blow to my chest, which really scares me.

At 31, is it normal for AFib to feel like a sudden blow to the chest?
Could this mean something more serious?

Every episode triggers panic, and I worry that my heart might stop or that something bad is about to happen. I am struggling to trust my body again and return to living normally. I have also started avoiding physical exertion because I am afraid it will trigger another episode.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I understand how frightening it can feel when your heart suddenly seems to thump or give a strong sensation in your chest, especially after being diagnosed with atrial fibrillation (AFib).

Many people with AFib describe a sudden thump, jolt, flutter, or the feeling of a blow in the chest. This is often because AFib causes an irregular heartbeat (a rhythm where the heart beats unevenly rather than in a regular pattern). Occasionally, after a brief pause between heartbeats, the next one can feel stronger, and this can be perceived as a distinct sensation.

By itself, this feeling does not necessarily mean that something more dangerous is happening or that your heart is about to stop.

At 31, it is important to continue working with your cardiologist (a doctor who specializes in heart conditions) to identify any possible underlying cause of AFib and ensure you are receiving the appropriate treatment. Once serious causes have been evaluated, gentle physical activity is often encouraged rather than avoiding exercise completely.

It is also understandable that anxiety can increase after experiencing unexpected heart sensations. Fear and stress can make you more aware of your heartbeat and may make symptoms feel more intense.

Seek urgent medical attention if you experience:

Severe or persistent chest pain.
Fainting or loss of consciousness.
Significant shortness of breath.
An episode that does not settle and makes you feel extremely unwell.

Otherwise, with proper evaluation, treatment, and follow-up, many people with AFib are able to return to normal activities and live fulfilling, active lives.

Thank you.

I hope this helps.
