Premature atrial contractions are not necessarily caused by heart disease. Most premature atrial contractions are caused by functional reasons, such as drinking strong tea, coffee, alcohol, poor rest, emotional anxiety, and stress, which can lead to premature atrial contractions. Other patients with serious infections or psychiatric disorders, such as anxiety, depression, or cardiac neurosis, may also experience premature atrial contractions. In addition, some patients may have heart disease itself, which can lead to atrial premature beats, such as hypertrophic cardiomyopathy, dilated cardiomyopathy patients will have atrial premature beats, the presence of coronary artery disease, angina pectoris can also lead to the emergence of atrial premature beats. Therefore, it is recommended that the patient undergoes further cardiac ultrasound and dynamic electrocardiogram to determine whether the patient has organic heart disease.
