Atrial ectopic beats occur normally and rarely cause any symptoms.
Causes and Risk Factors
These premature heartbeats are associated with lung diseases, especially if high blood pressure is present in the arteries that go between the heart and lungs. Stimulants (such as coffee and tea, alcohol or some types of cold, allergy or asthma remedies) will sometimes set off the extra beat.
Atrial ectopic beats happen more often in older people than younger ones.
