A new study by Chinese scientists from the Medical College of Qingdao University showed that higher heart rate is associated with an increased risk of death from all causes, even for those people who do not suffer from heart disease. According to experts, the relationship of heart rate with risk of death from all causes and cardiovascular mortality does not depend on the traditional risk factors for cardiovascular diseases, so heart rate can be a predictor of mortality in the general population.
Aside from being the predictor, the heart rate could also be monitored as a precaution with fingertip pulse oximeter. Scientists have proven how important it is to monitor the frequency of contractions of the heart muscles, if there is a tachycardia fibrillation. Such a strategy in the treatment is not less effective, than maintaining sinus rhythm.
But there’s a little complexity. Has not yet been identified, the optimal value of the heart muscle contractions, when there is an atrial tachycardia. But it still does not reject the value in tracking heart rate. At rest it should be equal to from 60 to 80 beats per minute. If you perform some simple physical work, the frequency increases from 90 to 115 beats per minute.
If you follow what this rate was to be observed by the OLED pulse fingertip oximeter, it will be possible to improve both the quality and the ability to carry the physical load. And this, in turn, will help to avoid heart failure. This means that the survival rate after heart attacks will increase.
These findings imply that people should pay more attention to the heart rate at rest, and also indicate the potential importance of physical activity to reduce heart rate.
