Guide To Atrial Fibrillation Symptoms

Lightheadedness And Dizziness

Atrial fibrillation prevents the lower chambers of the heart from filling completely, and this reduces the amount of blood pumped to the lungs and rest of the body. Patients may develop low blood pressure and many experience lightheadedness and dizziness as a result. Patients may feel as though they are about to faint, and some have fainting episodes. Individuals who feel lightheaded or dizzy should try to sit or lie down as soon as possible to reduce the risk of a fall. If a home blood pressure monitor is available, it can be beneficial to measure the patient's blood pressure at the time dizziness is experienced. Patients should report any episodes of dizziness to their medical team, and they should let their healthcare providers know if they are experiencing more frequent dizziness than usual.
