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
Causes of supraventricular tachycardia. Supraventricular tachycardia (SVT) is caused by a problem with electrical impulses in the heart. Heartbeats are normally initiated by a small group of cells at the top of the heart called the sinoatrial node, which acts as the heart's natural pacemaker.auses of supraventricular tachycardia.
