Can mono cause tachycardia

Yes, mononucleosis (mono), often caused by the Epstein-Barr virus, can lead to tachycardia. The infection may cause increased heart rate due to fever, dehydration, or the body's immune response. Additionally, complications such as splenomegaly can also contribute to an elevated heart rate. If someone experiences significant tachycardia with mono, they should consult a healthcare professional for evaluation.
