Associated with Down syndrome is an increased risk of hearing and vision defects, heart abnormalities (about 50% are born with congenital heart defects, for which the majority can be surgically corrected), infection, leukaemia, thyroid disorders, and of developing Alzheimer-type dementia in later life.
The heart beats normally around 35-40 000 000 times a year in normal conditions. (70 beat/minute) If you then also calculate (for a normal active person) 200 hours of workout â¦ during a year whit raising of the heart beat up to 180 times a minute you can easily pass 50 million heart beats a year.The heart has a capability of beating 70 millions times in one year.he heart beats about 100,000 times a day, on average.   Generally, the heart beats around 70 times per minutes, or just over 4,000 times per hour. (70 x 60 = 4,200) In a f â¦ ull day, that is about 100,000 beats.
An adult heart is about the size of two intertwined fists. Each day an average heart beats 100,000 times and pumps 2,000 gallons of blood. During a lifetime, the heart will pump 1 million barrels of blood. A heart will beat 2.5 billion times in an 80-year life. The body contains 60,000 miles of blood vessels. Every year since 1900 (with the exception of 1918) heart disease has killed more Americans than any other disease.
