Going for a long time with low intensity is much different from a quick burst of high intensity. This is where heart rate zones come in. Heart rate zones are ranges of beats per minute, based on your heart rate reserve. Heart rate reserve is found by subtracting your resting heart rate ...
The resting human heart rate is generally 60-100 beats/min (bpm) [1]. The heart rate of a mouse is 500–600 bpm [2], of a shrew is >1000 bpm [3] but of an elephant is only 30 bpm [4]. The rate-dependent cardiac output reserve in mice is small (+20–30%) compared to ...
The base case rate of hospitalization for heart failure is shown as a vertical line. Duration of disutility may also be interpreted as severity of quality-of-life impairment (eg, 2 months of disutility equivalent to 1 month of disutility twice as severe as the base case estimate). CV ...
This technique (called fractional flow reserve or FFR) is used to determine the severity of the blood vessel narrowing. Coronary angiography is seldom uncomfortable and usually takes 30 to 50 minutes. Unless the person is very ill, the person can go ...
To assess dyssynchrony, 2D speckle-tracking echocardiography (STE) is used to calculate global longitudinal strain. The advantage over the Doppler evaluation is its angle independence [63]. Patients with HFpEF have greater ventricular dyssynchrony compared to healthy people; this was expected, but ...
These distances are used to calculate the HRA index GI%, obtained using Equation (2). The number of points above and below the LI in subplots G–H corresponds to Poincaré plots in subplots C–D. Figure 3. A representative example of RR interval time series (A,B) for the two groups ...

70% of your “heart rate reserve” is a great estimate of the upper bounds of your Zone 2. If you choose to use approximately 70% of your heart ratereserve… here’s the formula. 70% of your heart rate reserve added to your resting heart rate (so your aerobic threshold would be 0.7...
value possible. The Kaplan-Meier method, log-rank test and univariate and multivariate Cox regression models (controlling for all main covariates such as age, gender, body mass index [BMI], and comorbidities) were used to calculate the survival rates, differences in survival curves, CV death ...
Postural Orthostatic Tachycardia Syndrome, also known as PoTS, is a condition in which the heart rate increases abnormally when you… FibriCheck’s new weight logging feature At FibriCheck, our goal is to empower you to take control of your heart health. In addition to our heart… ...
