Fever is a symptom of many different illnesses and is usually caused by an infection. A rise in body temperature signals the immune system to release more cytokines which are proteins that help fight the infection. One of the main types of cytokines is interleukin-6 (IL-6).
IL-6 is known to cause an increase in heart rate. In fact one study showed that heart rate increased by 10 beats per minute (bpm) for every 10 ng/mL increase in IL-6 levels. So if your body temperature is 38°C (100.4°F) your heart rate could be about 20 bpm higher than normal.
While a fever itself is not dangerous it can make your heart work harder than normal. If you have a heart condition you may be at risk for complications from a fever. If you have a fever and are worried about your heart talk to your doctor.
