A normal heart rate is between 60 - 100 times per minuet.
Sinus braydicardia is a heart rate below 60 BPM. A heart rate of 52 BPM may be dangerous but it depends on the underlying causes.
Sinus braydicardia can be causes by:
1) Rest- it can occur during sleep
2) Sinus node disease- which causes sinus node pauses
sinus braydicardia can causes hypotention ( low blood pressure 100 < 60< MMHG)
It can causes fainting and lack of blood supply to the brain. However Sinus braydicardia more often than not be harmless and a good heart rate for plenty of coronary blood flow
Treatment
Usally a heart rate below 60 does not need treatment if it is asymptomatic. However if it is symptomatic it may be treated by a pacemaker.
A heart rate of 52 may also be normal in athletes. For example Lance Armstrong's resting heart rate is 32-34 beats per minute. This is an extreme case however. So depending on your physical activity, age, weight and diet your rate could be lower then 60 with no negative effects.
that's a pretty low resting heart rate unless you are an athlete in great shape.
Everything from 65 to 95 BPM will be considered OK. Ideal heart resting heart rate for 56 years old would be 65-70 BPM. http://www.24by7info.com/heartrate/normal_heart_rate_in_adult.html http://www.24by7info.com/normalheartrateinadult/normal_heart_rate_in_adult.html
Heart rate (HR) is a measure of the number of heart beats per minute (bpm). The average resting human heart rate is about 70 bpm. Heart rate varies significantly between individuals based on fitness, age and genetics. Endurance athletes often have very low resting heart rates. Heart rate can be measured by monitoring one's pulse. Pulse measurement can be achieved using specialized medical devices, or by merely pressing one's fingers against an artery (typically on the wrist or the neck). It is generally accepted that listening to heart beats using a stethoscope, a process known as auscultation, is a more accurate method of measuring the heart rate. {| ! width="80" | Age ! width="120" | Normal heart rate(beats per minute | Newborn 120 Older Child 90-110 Adult 50-100 |}

The answer is 93526.51 Don't for get the modifier on the end, its a tricky question and it got me too. the 93526 is correct but not complete you need the 51 because it is a multiple procedure.
20% of 51= 20% * 51= 0.2 * 51= 10.2
that's a pretty low resting heart rate unless you are an athlete in great shape.
% rate:= 2/51 * 100%= 0.3922 * 100%= 39.22%
9.8%% rate:= 5/51 * 100%= 0.098 * 100%= 9.8%
14.49%% rate:= 51/352 * 100%= 0.1449 * 100%= 14.49%
% rate = 170% = 51/30 * 100% = 1.7 * 100% = 170%
percentage for 5 out of 51 = 9.8%% rate:= 5/51 * 100%= 0.098 * 100%= 9.8%
To find the unit rate, divide the total amount by the time. For 51 gallons in 14 minutes, the unit rate is calculated as 51 gallons ÷ 14 minutes, which equals approximately 3.64 gallons per minute.

35.17%% rate:= 51/145 * 100%= 0.3517 * 100%= 35.17%
% rate = 23.5294% = 12/51 * 100% = 0.235294 * 100% = 23.5294%
percentage = 63.75%% rate:= 51/80 * 100%= 0.6375 * 100%= 63.75%
