When you have heart failure, your heart tries to compensate for its lack of pumping power by beating faster (tachycardia) in order to keep up the same flow of blood around your body.

This increased heart rate may sometimes be irregular and cause palpitations which feel like your heart is racing or throbbing. You should discuss palpitations with your doctor or nurse.
