Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, a flow chart of a heart rate monitoring method according to an embodiment of the present invention includes, but is not limited to, the following steps:
step S101, the heart rate monitoring device acquires the current heart rate of the user.
The heart rate monitoring device can be wearable devices such as terminal devices or intelligent bracelets of an Android system and an IOS system with heart rate monitoring function, and can also be a server. Referring to fig. 2, a network architecture diagram provided by an embodiment of the present invention is shown in fig. 2, where the heart rate monitoring device is a server, and as shown in fig. 2, a heart rate acquisition device or a terminal device such as a mobile phone acquires a heart rate of a user, and transmits the heart rate to the server in a wired or wireless manner, so that the server acquires the heart rate of the user.
Step S102, when the current heart rate exceeds a preset heart rate range, the heart rate monitoring device determines that the current heart rate is an abnormal heart rate.
The heart rate range can be preset in the embodiment of the invention, and the preset heart rate range is generally the normal heart rate of an adult in medicine, such as 60-100 times per minute. The heart rate monitoring device may determine whether the obtained current heart rate of the user exceeds the preset heart rate range, if yes, the heart rate monitoring device may determine that the current heart rate is an abnormal heart rate, and if not, the heart rate monitoring device may further determine whether the current heart rate is an abnormal heart rate.
Step S103, when the current heart rate is within a preset heart rate range, if the difference between the current heart rate and the predicted heart rate in the same period is smaller than or equal to a preset heart rate threshold value, the heart rate monitoring device determines that the current heart rate is a non-abnormal heart rate; if the difference between the current heart rate and the predicted heart rate of the same period is greater than the preset heart rate threshold, the heart rate monitoring device determines that the current heart rate is the abnormal heart rate.
When the current heart rate of the user is within the preset heart rate range, the heart rate monitoring device may compare the current heart rate with the predicted heart rate in the same period, where in the embodiment of the present invention, the predicted heart rate in the same period may refer to the predicted heart rate of the user in the same period as the current heart rate, the predicted heart rate in the same period as the current heart rate may be generated according to the actually observed heart rate and the predicted heart rate in a period previous to the current heart rate, and the previous period may refer to a period previous to the predicted heart rate in the same period as the current heart rate, specifically:
the predicted heart rate calculation formula for the same period as the current heart rate is as follows:
F t+1 ＝αY t +(1-α)F t ……(1)
wherein ,Ft+1 To predict heart rate at the same time period t+1 as the current heart rate, Y t Is F t+1 Heart rate actually observed in a period t preceding the period of time, F t Is F t+1 The predicted heart rate of the period t preceding the period in which it is located, α being a weight coefficient.
The predicted heart rate can be generated according to the heart rate actually observed in the previous period of the period and the predicted heart rate, so:
F t ＝αY t-1 +(1-α)F t-1 ……(2)
wherein ,Yt-1 Is F t The heart rate actually observed in the period t-1 preceding the period of time, F t-1 Is F t The predicted heart rate for the period t-1 preceding the present period.
Substituting the formula (2) into the formula (1) to obtain:
F t+1 ＝αY t +(1-α)[αY t-1 +(1-α)F t-1 ]……(3)
again because:
F t-1 ＝αY t-2 +(1-α)F t-2 ……(4)
substituting the formula (4) into the formula (3) to obtain:
by analogy in turn,
F t+1 ＝αY t +(1-α)[αY t-1 +(1-α)F t-1 ]
＝αY t +(1-α)αY t-1 +(1-α) 2 αY t-2 +……+(1-α) n αY t-n +……(1-α) t F 1 ……(6)
wherein ,Yt-2 For period t-2 the heart rate actually observed, Y t-3 For period t-3 the heart rate actually observed, Y t-n For the period t-n the heart rate actually observed, n being a positive integer, F 1 Heart rate predicted for period t=1.
Alpha is a weight coefficient, and is generally understood as that the actual observed heart rate closer to the predicted heart rate in the period of time gives a larger weight to the predicted heart rate, and the actual observed heart rate farther from the predicted heart rate in the period of time gives a smaller weight to the actual observed heart rate, and the weight is regularly decreased from near to far, for example, taking the weight coefficient alpha=0.7.
Predicted heart rate F for period t=1 1 The actual observed heart rate Y for the same period t=1 can be taken 1 Or taking the heart rate Y actually observed for the period t=1, the period t=2, and the period t=3 1 、Y 2 and Y3 Average of the three, e.g. F when the number of samples, i.e. the number of actually observed heart rates per period, is greater than 42 1 The actual observed heart rate Y for the same period t=1 can be taken 1 F when the number of samples is less than 42 1 Can take Y 1 、Y 2 and Y3 Average of the three.
In addition, as can be seen from formula (6), the term (1-. Alpha.) is a decimal fraction ranging from 0 to 1, and when t is larger, the term (1-. Alpha.) t Near 0, similar (1-alpha) t F 1 The term pair F with large (1-alpha) index is equal to exist t+1 Less influence of F t+1 The first three terms in equation (6) can be taken for the calculation, namely:
the heart rate threshold value can be preset, the heart rate monitoring device can compare the current heart rate with the calculated predicted heart rate in the same period, if the difference value between the current heart rate and the calculated predicted heart rate is smaller than or equal to the preset heart rate threshold value, the heart rate monitoring device can determine that the current heart rate is an abnormal heart rate or a normal heart rate, otherwise, if the difference value between the current heart rate and the calculated predicted heart rate is larger than the preset heart rate threshold value, the heart rate monitoring device can determine that the current heart rate is an abnormal heart rate.
The heart rate of the user in the current period t+1 is Y, which is acquired by heart rate monitoring equipment t+1 The predicted heart rate of the user for the period t+1 calculated according to the above formula (7) is F t+1 Heart rate monitor device alignment Y t+1 、F t+1 Calculate Y t+1 、F t+1 The difference between the two (e.g. Y t+1 -F t+1 Or F t+1 -Y t+1 ) If the difference between the two is calculated to be smaller than the preset heart rate threshold T threshold Determining that the current heart rate is a normal heart rate, if the difference between the current heart rate and the normal heart rate is calculated to be greater than or equal to a preset heart rate threshold T threshold Then the current heart rate obtained is determined to be an abnormal heart rate. Wherein the preset heart rate threshold T threshold Can be determined according to parameters such as normal heart rate variation of adults and the like, and is not limited herein.
In the embodiment of the invention, when the abnormal heart rate is monitored, the heart rate monitoring equipment can also alarm, such as sending out drip alarm sound, or sending alarm signals to terminals such as smart phones connected with the heart rate monitoring equipment, so that the terminals can alarm, such as the heart rate monitoring equipment is a smart bracelet, when the smart bracelet monitors the abnormal heart rate, the alarm signals can be sent to the smart phones connected with the heart rate monitoring equipment, so that children of the solitary old can conveniently know the abnormal heart rate of the elderly, and only the elderly is provided with the smart bracelet, when the smart bracelet monitors the abnormal heart rate of the elderly, the children can directly send out an alarm to the mobile phones of the children connected with the smart bracelet, the children can timely know the heart rate of the elderly, the aged can be timely cured, and in addition, the heart rate monitoring equipment can also directly send out an alarm to platforms such as an emergency center.
Therefore, the embodiment of the invention can monitor the heart rate in the normal heart rate range in the prior art by comparing with the predicted heart rate in the same period, and finds that the abnormal heart rate in the normal heart rate range in the prior art can be monitored, so that the monitoring effectiveness of the abnormal heart rate is improved, and the problem that the patient delays the treatment opportunity due to incapacity of monitoring the abnormal heart rate is avoided, thereby providing a guarantee for timely treatment of the patient when the heart rate is abnormal.
