I'm really thin and I've noticed that I'm very aware of my heartbeat. I can even see the muscle on the left side of my chest moving with it. I've done a Holter, ECG, and ECHO, and they all came back normal. Should I be concerned about this?

It's understandable to be concerned when you notice your heartbeat so clearly, especially when you're thin and can see the muscle movement on your chest. Since your Holter monitor, ECG, and echocardiogram (ECHO) all came back normal, this is reassuring and suggests that your heart is functioning well.

Key points to consider:

1. Visibility of Heartbeat:

   • Being thin can make your heartbeat more visible and palpable, which is often normal.

2. Palpitations:

   • Awareness of your heartbeat can sometimes be heightened by anxiety or stress.

3. When to Seek Medical Advice:

   • If you experience symptoms like dizziness, chest pain, shortness of breath, or fainting, seek medical advice promptly.

4. Regular Monitoring:

   • Continue regular check-ups as advised by your doctor to monitor your heart health.

If you remain worried or notice new symptoms, discussing this with a cardiologist or your primary care physician can provide further reassurance and guidance. For now, your normal test results are a positive sign that there is no underlying heart problem.
