Heart failure causes reduced blood flow to the rest of your body. If the flow to your brain is lower than usual or your blood pressure is low, you may feel dizzy.
Dizziness in people with heart failure is often caused by their medicines. However, irregular heart beats , which often happen with heart failure, or a temporary drop in blood pressure cuased by rising from a sitting or lying position (postural hypotension) can also cause dizziness.
You should discuss any dizziness with your doctor or nurse to identify its cause.
