For example, clinic measured data can be artificially increased in a similar phenomenon to “white-coat hypertension” 4 or by an increased adrenergic reaction to the clinical settings. 3 However, these commonly accepted norms are derived using in-clinic recorded HR which may not be representative of the real-world, outside of a healthcare institution, remotely obtained measurements that are commonly recorded by a growing number of consumer devices. 1– 5 Several studies, as well as expert consensus, indicate that the normal adult resting HR values lie between 60 and 90 beats per minute (bpm), 1– 3 and the American Heart Association defines the normal sinus HR as between 60 and 100 bpm. Generally, lower HR has been associated with lower all-cause and cardiovascular mortality. Heart rate (HR) is a readily available vital sign that holds important prognostic information. Our study provides the largest real-world norms for remotely obtained, real-world HR according to various strata and they may help physicians interpret and engage with patients presenting such data. In multivariable linear regression, the number of medical conditions, female gender, increasing body mass index, and being Hispanic was associated with an increased HR, whereas increasing age was associated with a reduced HR. The 95th percentile of real-world HR was ≤110 in individuals aged 18–45, ≤100 in those aged 45–60 and ≤95 bpm in individuals older than 60 years old. The mean real-world HR was 79.1 bpm ± 14.5. A total of 66,788 Health eHeart Study participants contributed 3,144,332 HR-PPG measurements. HR-PPG and HR-ECG were highly correlated (Intraclass correlation = 0.90). We then used data from participants enrolled in the Health eHeart cohort between 1 April 2014 and 30 April 2018 to derive real-world norms of HR-PPG according to demographics and medical conditions. To validate the measurements, we obtained simultaneous HR-PPG and HR-ECG in 50 consecutive patients at our cardiology clinic. Our goal was to validate HR-PPG, measured using a smartphone app, against HR-electrocardiogram (ECG) measurements and describe out-of-clinic, real-world, HR-PPG values according to age, demographics, body mass index, physical activity level, and disease. However, the validity and expected distribution of such measurements are unclear, making it difficult for physicians to help patients interpret real-world, remote and on-demand HR measurements. If you have a heart condition, be sure to discuss your target heart rate with your doctor prior to beginning an exercise program.Emerging technology allows patients to measure and record their heart rate (HR) remotely by photoplethysmography (PPG) using smart devices like smartphones. The device is worn like a bracelet or watch and measures your heart rate.Įxercising at the right level of intensity improves heart and respiratory endurance and helps keep your workout at a level that is vigorous enough to meet your health goals. Wearing a multifunctional fitness tracker such as the Fitbit, or Nike+ FuelBand SE, does the work for you. If your heart rate is 50 to 85 percent of your maximum heart rate, you have hit your target heart zone and are working at the right level of intensity. ![]() Count your pulse for ten seconds and multiply this number by six. To determine your heart rate, use your first two fingers to press lightly over the blood vessels on your inner wrist-the side by your thumb. The following is an estimate given by the American Heart Association for target heart rate numbers for adults ages 45 to 70: Target heart rate is defined as the minimum number of heartbeats in a given amount of time in order to reach the level of exertion necessary for cardiovascular fitness, specific to a person’s age, gender, or physical fitness. ![]() This specific type of exercise gets your heart beating fast for several minutes at a time. Help your heart work strongerĬardiovascular exercise (also called aerobic exercise) is especially effective in keeping your heart healthy and reaching your target heart rate. Exercising at the right level of intensity will help you avoid burning out or wasting time with a workout that’s not vigorous enough to help you meet your goals. ![]() So knowing your target heart rate helps you pace your workouts. Sustaining a workout at this pace improves cardiorespiratory endurance.
