Changes in heart rate may signal COVID-19
In addition to the main symptoms, your heart rate may signal you have COVID-19, Express writes.
According to the COVID Symptom Study app, a not-for-profit initiative that has pooled together data from over four million contributors globally, your heart rate may hold a clue.
According to researchers behind the app, COVID-19 can cause an irregular or high heart rate (over 100 beats per minute).
"Get in the habit of measuring your pulse regularly so you can recognise the normal rate and rhythm of your heart and know if yours is changing," they advise.
According to the app's health experts, you can record your heart rate and identify any worrying changes by implementing four simple steps.
Normal resting heart rate is considered to be between 60 and 100 beats per minute (bpm).
As the app's researchers note, your heart rate could be slower if you exercise a lot or take medication like beta-blockers. "A normal heart can miss a beat occasionally," say the researchers.
"See your doctor if your heartbeat continues to be irregular and you’ve not already been diagnosed with a heart condition," they add.
