Does thyrotoxicosis causes heart murmurs?

A doctor has provided 1 answer

High flow: Yes, this is common. Thyrotoxicosis increases cardiac output and the increased flow of blood can often create a "flow murmur". Although your doctor may want to do an echo to check it out, a flow murmur from hyperthyroidism is benign and usually goes away with treatment of the thyroid.
