Sweet Potato Storage. Unlike potatoes, fresh sweet potatoes generally do not store well, except under ideal conditions, and bruised ones rapidly deteriorate. In a dry, dark, cool (55 degrees F.) place, they can last up to three to four weeks. Plan on using within one week of purchase and do not refrigerate.
During an episode of supraventricular tachycardia (SVT), the heartbeat is not controlled by the SA node (the normal timer of the heart). Patient Access Register
Typically, SVT occurs in discrete episodes, which most often begin suddenly and stop suddenly. The duration of episodes can be from a few seconds to several hours. During an episode of SVT, the heart rate is at least 100 beats per minute, but in some people can become substantially faster than 200 beats per minute. SVT commonly produces palpitations - a feeling of having extra heart beats or of a racing heart, which can be quite scary.
