Resting heart rate (RHR) refers to the number of heart beats per minute when the human body is awake and quiet, reflecting the level of sympathetic nerve activity, autonomic balance and metabolic rate of the body, and was firstly proposed by Prof. Levy in the 1940s. Studies have shown that accelerated RHR is an independent risk factor for the development of hypertension. Hypertension and heart rate A cohort study of more than 30,000 people showed that for every 10 beats/min increase in heart rate, the incidence of hypertension increased by 8%. Ji Chunpeng et al. included more than 30,000 people with normal high-value blood pressure and showed that the odds of developing hypertension increased 1.25 times in the ≥85 beats/min group compared with the 70-74 beats/min heart rate group. Accelerated RHR is also an independent influence on the prognosis of hypertensive patients. It has been shown that hypertensive patients with chronically accelerated RHR have higher cardiovascular and all-cause mortality rates, and that there is a 25% increase in deaths from cardiovascular events for every 10 beats/min of accelerated RHR, and that this effect is independent of the efficacy of antihypertensive therapy. In addition, hypertension combined with accelerated RHR is likely to be accompanied by obesity.Palatini et al. observed more than 1,000 cases of hypertensive patients, followed up for 7 years, and found that the proportion of overweight or obesity was significantly higher in those with accelerated RHR. Increased RHR is a visual reflection of sympathetic over-activation in hypertensive patients, and changes in heart rate are easy to observe and detect, so heart rate is often referred to as a window for evaluating sympathetic activity, and elevated heart rate can cause adverse cardiovascular events, which is an important prognostic factor independent of blood pressure. Most current studies use heart rate during follow-up or 24-h ambulatory electrocardiograms to determine the presence of an accelerated resting heart rate, utilizing a four- or five-quartile spacing to delineate the heart rate of the target population, and generally a heart rate of >80 to 85 beats/min is referred to as an accelerated resting heart rate. Heart rate measurement methods Heart rate measurement methods include in-office heart rate measurement, out-of-office heart rate measurement, self-tested heart rate, and ambulatory heart rate detection, and the data obtained from different measurement methods are different. In clinical practice, we recommend that resting heart rate be used as the primary basis for heart rate assessment: Avoid exercise before measurement, allow the patient to relax and rest for 5 minutes, avoid background noise and conversations, prefer seated measurements, the patient should be seated comfortably in a chair and not have his or her legs crossed, the heart rate should not be counted for shorter than 30 seconds by palpation of the pulse, the heart rate can be counted by electrocardiogram, but this is not preferred, the heart rate should be checked after each blood pressure measurement, and the heart rate should be measured at least once after each measurement, and the heart rate should be measured at least once after each measurement. Heart rate should be checked after each blood pressure measurement. Heart rate should be measured at least twice and averaged, and the results may vary depending on the method used to measure the heart rate. How to control RHR Resting heart rate can be disturbed by mood swings, sleep quality, alcohol, smoking, tea, exercise and medication. If there is no influence from the above mentioned factors, but the resting heart rate is often fast, you should go to the hospital for relevant examinations and early prevention and intervention. Lifestyle interventions should be preferred to control the resting heart rate, including reducing the intake of coffee and strong tea, quitting smoking, quitting drinking, losing weight, getting enough sleep, exercising appropriately, and maintaining a happy mood. If it still fails to slow down the heart rate, then it should be treated with medication under the guidance of a doctor.
