Below is an instruction that describes a task.

Main symptoms were swollen lymph nodes on the left side on my neck and armpit and frequent heart palpitations.Symptoms went away until April, when I started having sudden heart palpitations randomly throughout the day. When the palpitations end, my the same neck and armpit lymph nodes swell up painfully for several hours.Symptoms got bad enough that I thought I was dying and went to the ER. Not dying, just something that can happen post-covid. Minor abnormalities on ECG, Doctor explained why they weren't concerning in my case.After a couple months of reducing caffeine intake as much as possible ( about 2 cups of coffee before work, no more canned coffees or caffeinated tea at work), it seemed to have gone away.About two days ago, it came back. Didn't recognize the symptoms for what they were and went to the ER again. Slightly different abnormal but not concerning ECG. Blood pressure was high, went back down to normal by the time I was discharged. Negative COVID-19 test. Same left side lymph nodes painfully swollen.My Question for AskDocs:I plan to see a cardiologist about the heart palpitations since they have been so frequent after coming back.Is there any other specialty that might be able to help me? Or would making sure my heart is okay be enough?. ### Response: Cardiology will handle the palpitations.Without seeing your ekgs I can't tell you much more. There are many causes of palpitations, if the ER discharged you then the palpitations we're probably due to PACs or PVCs which can be treated by your PCP or cardiologist to reduce your symptoms, but like I said, can't say much more without the ekgs or more info..
