Hypertension can cause premature beats, but there are many reasons for premature beats, and hypertension is only one of them. Long-term hypertension can lead to fibrosis of the heart lining, resulting in lesions in the conduction system of the heart, and it can also cause structural changes in the heart, especially when the atria become larger, which can significantly increase the risk of premature beats and even atrial arrhythmias. In addition, when blood pressure is too high, the pumping pressure of the heart increases, which can also lead to premature beats. There are many reasons for premature beats, hypertension is only one of them. Another major reason for premature beats is due to mental and psychological activity disorders, such as staying up late, emotional stress or mood swings, which can also cause premature beats.
