Can heart palpitations cause fainting?

No: Heart palpitations is a symptom. As a general rule, causes of fainting (i.e. Loss of consciousness) are not symptoms.

Yes: Dependent on the cause of palpitations, if the person is having very fast cardiac arrhythmias, he/she can very well pass out (faint). The fast heart rate or the type of arrhythmia can cause a low cardiac output state leading to low blood pressure and the resulting fainting episode.
