Can pneumonia cause prolonged QT waves?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I went to the emergency room with a rapid heartbeat. The doctor performed an EKG and chest X-ray and diagnosed me with pneumonia. However, my QT interval was slightly prolonged. He repeated the EKG a week later and said it was normal. Should I be concerned about the prolonged QT? Could pneumonia have caused it?

Please suggest.

Hi,

Welcome to icliniq.com.

How long was your QT interval? Pneumonia does not typically cause QT prolongation. Since it has resolved, it was likely due to reversible causes, such as electrolyte imbalances like hypocalcemia or hypokalemia. Many medications can also cause QT prolongation, so it is important to review any drugs you are taking. However, it would be wise to repeat the ECG (electrocardiogram) in three to four weeks to ensure the QT interval is not prolonged.

I hope this helps, and feel free to reach out if you have any questions.
