I saw a post today discussing palpitations after COVID. Folks, what I tell my patients is: if you get palpitations in the weeks to months after COVID, call your doc and get seen. Here’s why — palpitations after COVID are common, and one prevalent cause is atrial fibrillation. This is often detected by a wearable event recorder such as a Holter monitor, because a 1-time ECG (as if often done in the ER) is worthless if you aren’t in a-fib at the time. A-fib dramatically increases stroke risk.
