Sinus tachycardia is the name for a pulse that beats regularly but faster than 90bpm.
It happens when your body sends out electrical signals to make your heart beat faster, and it can be a result of hard exercise, anxiety, certain drugs or a fever.
You’re at a higher risk of having this problem if you have diabetes, heart disease, anaemia, high blood pressure or any other condition that puts a strain on the heart.
Sinus tachycardia isn’t to be taken lightly as complications can lead to blood clots, heart attacks, strokes, heart failure, loss of consciousness or sudden death.
Always see a doctor if your resting pulse is higher than 90bpm and treat any symptoms it comes with such as fainting, dizziness, headaches, chest pain, anxiety and inability to exercise as an emergency.
