心率（Heart rate）是指心脏每分钟跳动的次数（bpm）。静态心率（Resting heart rate）是指人体在完全静止状态下的心率，衡量心脏健康程度最快且最简单的方法就是检查静止心率（RHR、也有人称安静心率）。RHR是许多其他健康指标的参考数据（如血压、压力和睡眠不足）。静态心率，应至少符合4个条件：1、清醒状态；2、...
A person's target heart rate zone is between 50% and 85% of their maximum heart rate,according to the AHA. Most commonly, maximum heart rate is calculated by subtracting your age from 220. So for a 30-year-old person, for example, the maximum heart rate would be 190 bpm: 220 – 30...
Fetal Heart Doppler AD51H can detect oxygen saturation and fetal heart rate. This pregnancy heartbeat monitor can connect to cell phones via Bluetooth.

(i) the alert did not include BB if the patient had a last documented heart rate <60 bpm; (ii) the alert did not include ACE-I/ARB/ARNI if the most recent serum potassium was >5.5 mmol/L, they were pregnant, ...
What is a good heart rate by age? After adolescence, a medically normal heart rate for any age adult is anywhere between 60 and 100 bpm. Most healthy adults have a heart rate of 55-85 bpm. What's an unhealthy heart rate? Trained athletes can have very low heart rates, and children ...
Heart Rate Monitor is the latest safe, accurate and visual pulse app checker & monitor & step counter on the market, feature-rich & easy to use, timely access t…
Heart rate was measured by direct visual observation through transparent mussel shells. The average heart rate for all 7 species at 20 °C was 55 bpm, with a range from 38 bpm ( L. recta) to 65 bpm ( P. alatus). L. recta and V. delumbis exhibited significant changes in heart rate...
Remote photoplethysmography (rPPG) gains recent great interest due to its potential in contactless heart rate measurement using consumer-level cameras. This paper presents a detailed review of rPPG measurement using computer vision and deep learning techniques for heart rate estimation. Several common gaps...
a Mean absolute error in heart rate (bpm) across devices during rest (teal) and activity (orange). This shows the true difference in HR from the ECG but does not show the sign of the difference. The green horizontal line represents no error (no difference from the true measurement of HR...
