Is it true that long COVID causes persistent heart problems such as palpitations and myocarditis?

Yes. A Wikipedia reference and an ESC scientific statement both state that long COVID patients experience palpitations/tachycardia and myocarditis or peri-myocarditis, directly covering the claim. Additional peer-reviewed items report persistent heart inflammation and cardiac dysfunction after COVID-19, though some address COVID-19 generally rather than long COVID specifically.
