Dysrhythmias is also known as cardiac dysrhythmias, which can be described as an irregular heartbeat, that is an abnormal rhythm of the heartbeat, which may be due to the changes in the heart's normal sequence of electrical impulses.

Reasons why teenagers think it is good to date
Grace [21]

Answer:

Dating, especially during the teenage years, is thought to be an important way for young people to build self-identity, develop social skills, learn about other people, and grow emotionally.

Explanation:

While some teens tend to be interested in dating earlier than others, romantic interests are normal during adolescence. Girls are more vocal about the dating interest and tend to be interested in a greater degree at a younger age, but boys are paying attention also.

For many kids, 16 seems to be an appropriate age, but it may be entirely suitable for a mature 15-year-old to go on a date, or to make your immature 16-year-old wait a year or two.

I believe you need to be mature and understanding, and responsible if you want to have a relationship. Because it can lead to cheating, depression and sui.cide, which is NOT RIGHT!

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)
