What is the cure for intense fear and rapid heartbeats when praying aloud or reciting the Quran in front of a congregation, which immediately disappear afterward?

The discomposure a reader experiences when reciting in front of people is something that afflicts some individuals who are unaccustomed to public recitation, and it may disappear with practice. He should be sincere to Allah, ponder the Qur’an, and contemplate Allah's greatness and His watchfulness, for this may alleviate what he experiences.
