In this case, the longitude is also called the right ascension of the ascending node (RAAN). The angle is measured eastwards (or, as seen from the north, counterclockwise) from the FPA to the node. [2] [3] An alternative is the local time of the ascending node (LTAN), based on the local mean time at which the

In a normal heart, the heart rate is the rate at which the sinoatrial node depolarizes since it is the source of depolarization of the heart. Heart rate, like other vital signs such as blood pressure and respiratory rate, change with age. In adults, a normal heart rate is between 60 and 100 bpm (normocardic), whereas it is higher in children. [56]
Those are times to seek out help because it may not be a reflection of your resting heart rate, but an abnormal heart rhythm that should get evaluated.” Having a pulse over 100 bpm is called ...
The atrioventricular node or AV node electrically connects the heart's atria and ventricles to coordinate beating in the top of the heart; it is part of the electrical conduction system of the heart. [1] The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, and conducts the normal ...
As you get older, your heart and blood vessels may start to undergo physical changes that could put you at risk of developing heart disease or heart failure, and it may influence your heart rate ...
An orbiting body's mean longitude is calculated L = Ω + ω + M, where Ω is the longitude of the ascending node, ω is the argument of the pericenter and M is the mean anomaly, the body's angular distance from the pericenter as if it moved with constant speed rather than with the variable speed of an elliptical orbit.
A good time to check your heart rate is in the morning after you’ve had a good night’s sleep, before you get out of bed or grab your morning coffee, says Dr. Steinbaum.
