What happens to irregular pulse with exercise?

Some forms of irregular pulse become regular with exercise while others remain so may even worsen. Those with irregular rhythm due to abnormal beat originating from certain parts of the ventricle disappear with exercise. They are generally considered as a harmless irregularity. This is because the increase in heart rate with exercise suppresses the abnormal focus of electrical activity by over riding it with higher rate. But certain irregularities due to disease states increase with exercise and they could be more harmful. Certain other forms of irregularity remain unchanged with exercise.
