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.
The US National Institutes of Health has published a list of normal resting heart rates. The pulse gets progressively slower through childhood toward adolescence. The normal resting heart rate for adults, including older-aged adults and everyone over the age of 10 years, is between 60-100 heartbeats a minute.4. Athletes who have done a lot of training may see their resting heart rate fall below 60 beats a minute, possibly to as low as 40 beats a minute.
