It's well known that anxiety can cause heart palpitations, and it's believed that the main cause may be an over-awareness of one's own heart, combined with surges of adrenaline that may occur at random in those with anxiety. These types of palpitations often trigger panic attacks. Panic attacks themselves can also cause palpitations. During a panic attack, two things occur that lead to rapid heartbeat: First, the sympathetic nervous system is on high alert, which may lead to a rapid increase in heart rate. Second, during panic attacks, people often have a tendency to hyperventilate.
