It's when your heart slows down to less than 60 beats per minute. This could be normal for you, especially if you're athletic. You probably don't need treatment unless you have symptoms. Sinus bradycardia is unlikely to cause you complications unless your heart rate goes below 40 beats ...
The device’s heart rate sensor usesinfrared light to measure normal heart rate readings when you’re not working out, as well as elevated heart rates. By contrast, green LED lights on the sensor are polled when measuring your heart rate during workouts and Breathing sessions and to calculate ...
The fetal heart rates of 340 normal singleton pregnancies at 30–33 weeks gestation were screened using a microprocessor system on-line. Eleven fetuses (3·2%) with a heart rate variation less than the 5th centile were identified, of whom 10 were studied longitudinally. At 30–33 weeks the ...
Systolic, the higher number, measures the pressure during heartbeats. Normal is below 120 mmHg. High systolic pressure suggests heart strain. Diastolic, the lower number, measures pressure when the heart is at rest. Normal is below 80 mmHg and shows artery relaxation. A team of researchers from...
Serum creatinine ranges are lower for women because women have less muscle mass and, thus, a lower rate of creatinine formation and excretion. Normal blood creatinine levels also vary by race. For non-Hispanic blacks, the average blood creatinine is 1.25 mg/dL in men and 1.01 mg/dL in wome...
To determine whether the VO2 response to exercise is altered when heart rate is significantly reduced by heart disease, we compared 78 children who achieved a peak exercise heart rate of 150 beats/min to 201 controls of similar body size and normal peak exercise heart rates of 180 beats/min...
Normal range of body temperature based on age For a typical adult,body temperaturecan be anywhere from 97 F to 99 F. Adults over the age of 60 tend to have a lower body temperature, compared to younger adults. Babies and children have a wider range: 95.9 F to 99.5 F (if measured wit...
The relationship between age-related heart rate changes and developing brain function: a model of anencephalic human fetuses in utero We attempted to identify the brain segment which controls heart rate changes in human fetuses with advancing gestation. Twelve anencephalic and 165 normal ... T ...
ECG, electrocardiogram; E:I, expiration:inspiration ratio; VFC, heart rate variability; HFnu, normalized high-frequency power; LFnu, normalized power of low frequency; NA, not applicable; SDNN, standard deviation of all normal R–R intervals recorded in a time interval (ms). ...
