The heart rate is one of the ‘vital signs,’ or the important indicators of health in the human body. It measures the number of times per minute that the heart contracts or beats. The speed of the heartbeat varies as a result of physical activity, threats to safety, and emotional responses. The resting heart rate refers to the heart rate when a person is relaxed.
While a normal heart rate does not guarantee that a person is free of health problems, it is a useful benchmark for identifying a range of health issues.
As per NIH (National Institutes of Health, USA) and AHA (American Heart Association) the normal resting heart rate can be between 60-100 BPM based on lifestyle and physiology.
Though there are generic values for normal resting heart rate (60-100 BPM), every person’s vitals are different and vary as per their routine and health. For example, an athlete’s resting heart rate can be between a range of 45 BPM to 55 BPM while a person with mild diabetes might have a resting heart rate in the range of 65 BPM to 75 BPM. Dozee learns from your data, personalizes and builds these baselines for you, and alerts you if your vitals show variations from the baselines. These baselines are updated every week. It takes approximately 5 nights of data for Dozee to compute the baselines.
Tachycardia is a fast or irregular heart rhythm, usually more than 100 beats per minute. At these elevated rates, the heart is not able to efficiently pump oxygen-rich blood to your body. Tachycardia can occur in either the upper heart chambers (atrial tachycardia) or lower heart chambers (ventricular tachycardia).
Certain conditions can increase your risk of developing tachycardia:
Bradycardia is a slower than usual heart rhythm, usually less than 50 beats per minute. If you’re an athlete or someone who exercises often, a lower resting heart rate isn’t usually anything to be worried about, unless you’re dizzy, tired, or ill. In fact, it typically means you’re in good shape. However, if you do feel any of the above coupled with low heart rate it may be because of following underlying causes:
An athlete’s resting heart rate may be considered low when compared to the general population. A young, healthy athlete may have a heart rate of 30 to 40 bpm. That’s likely because exercise strengthens the heart muscle. It allows it to pump a greater amount of blood with each heartbeat. More oxygen is also going to the muscles. This means the heart beats fewer times per minute than it would in a nonathlete.
