Heart Palpitations Causes & Risk Factors

Heart palpitations occur when the heartbeat suddenly speeds up. The person suffering palpitations may feel his heart has skipped a beat or is racing, but in some cases the heart rate may still be within a normal range. There are several causes and risk factors that can lead to heart palpitations.

Medications

• Thyroid drugs, asthma pills and inhalers, beta-blockers, and pills used to treat abnormal heart rhythm can all cause heart palpitations.

Stimulants

• Stimulants such as caffeine, cocaine, nicotine, and over-the-counter or prescription diet pills can also create heart palpitations.

Exercise

• Exercising can cause palpitations. Remember that sometimes heart palpitations are felt outside the chest, such as in the throat or neck.

Medical Conditions

• Those with medical conditions such as heart disease, anemia, or overactive thyroid are at greater risk for palpitations.

Emotional Factors

• Anxiety, stress, and hyperventilation are all causes and risk factors for heart palpitations.
