You're definitely not the lone ranger here! There is actually a known connection between MG and heart issues worth understanding.

In MG, the same autoimmune process that attacks neuromuscular junctions can sometimes also target cardiac muscle. This is particularly noted in people who have a thymoma (a thymus gland tumor). When the heart is affected, it can lead to:

- Irregular heart rhythms (arrhythmias)
- Heart muscle inflammation (myocarditis)
- Heart failure in more serious cases Given that your symptoms have been escalating over two to three months — especially the lightheadedness and needing to cough to reset your rhythm — it would be really worth having a direct conversation with your neurologist about whether your MG could be contributing to what's happening with your heart.

Your care team should ideally be communicating with each other about this, since MG can sometimes be the missing piece of the puzzle that cardiologists aren't always looking for.

Please don't ignore worsening lightheadedness or chest pain — if symptoms become severe, seek emergency care right away.
