[|Human|] I had the flu two weeks ago. I just caught what feels like a mini version. No fever, but I cough and have nasal drip and Im pretty weak feeling. Im on the third day of it. I am 34 years old, male. No health issues. I do feel my heart flutter once and while and just feel tired.. Is this a normal reaction to being sick?
[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that this feeling looks like a paroxysmal cardiac arrhythmia (an episode of atrial fibrillation or flutter, frequent ectopic beats or even ventricular arrhythmia, etc.). There is only one way to confirm any possible arrhythmic events, by means of ECG registering during such unpleasant feelings. The most appropriate option would be to undergo an ambulatory 24 to 48 hours ECG monitoring (Holder test). In addition, I would recommend you to perform a medical check up by your internist or cardiologist, for a comprehensive physical exam, a resting ECG, chest X-ray study, some additional lab tests like complete blood count, PCR, Thyroid, liver, renal function tests, blood electrolytes, etc., to rule in/out any possible flu complications, like thyroiditis, pericarditis, myocarditis, etc. that may lead to generation of cardiac arrhythmias and altered overall health status. A cardiac ultrasound would be necessary, if suspicions of myo-pericarditis, etc. are raised. Hope to have been helpful! Greetings!
