Changes in heart rate or rhythm are called
arrhythmias. They may reduce the amount of blood flow
from the heart (cardiac output) to the brain and the rest of the body.
Decreased blood flow to the brain can cause you to pass out suddenly (syncope). In some cases, you may feel short of breath
palpitations or chest discomfort before you faint.
Heart rate or rhythm changes also can occur when you are anxious
or afraid or in a stressful situation. Feeling worried, anxious, and nervous
may increase your heart rate, and you may feel lightheaded or like you are
going to faint.
