The SARS-CoV-2 coronavirus causes COVID-19, a disease that damages heart muscle and impairs cardiac function.

This is due to a number of factors. The coronavirus connects to angiotensin converting enzyme-2 (ACE-2) receptors on cardiac cells before entering them. High levels of inflammation circulating in the body can potentially cause heart damage. The inflammatory process that occurs while the body’s immune system battles the virus can harm some healthy tissues, including the heart.

Coronavirus infection affects the inner walls of veins and arteries, causing blood vessel inflammation, damage to extremely small capillaries, and blood clots, all of which can obstruct blood flow to the heart and other regions of the body.

If you experience a rapid heartbeat or palpitations after COVID-19, you should consult your doctor. A brief acceleration in heart rate can result from a variety of factors, including dehydration. Make sure you’re getting enough water, especially if you’re suffering from a fever. A fast or irregular heart beat might cause the following symptoms:

Feeling your heart pounding in your chest quickly or irregularly

Lightheadedness or dizziness, especially when standing

Uncomfortable chest
