Having heart palpitations could be one of the earliest signs of high blood pressure, said Bupa UK.
Heart palpitations cause people to feel their own heart beat. It may feel like a pounding in the chest, added charity the British Heart Foundation.
It could even be felt in the neck, or heard in the ears when lying down, it said.
“Palpitations describe the sensation of feeling your own heart beating,” said the British Heart Foundation.
“They often feel like a fluttering, pounding, a thud or movement in your chest, which you may feel in your neck or through your ear when you are lying down.
“Palpitations are common and for most people are harmless, but they can be very unpleasant.”
