Vitalik buterin, 27, co-founder of Ethereum, is now the world's youngest cryptocurrency billionaire. Previously, the price of his cryptocurrency has risen 3% so far this year, with a total value of about $1125299854 as of 8:19 a.m. EDT on May 4, compared with $3374.90 at the ether Museum. As the second most popular cryptocurrency, Ethernet's market value is close to $400 billion, reaching a high of more than $3500 per share before the decline{ RRRRR}

SSS is the congruent condition of triangle
congruent triangle refers to two congruent triangles whose three sides and three angles should be equal. Congruent triangle is one of congruent triangles in geometry. According to congruent transformation, two congruent triangles can be translated, rotated, axisymmetric, or overlapped. There are five ways to judge congruent triangles: SSS, SAS, ASA, AAS and HL (right triangles only)
extended data:
five methods to verify congruent triangles; The three sides are equal in length
SAS (side angle side, edge, corner, edge; side angle side, side angle, side angle, side angle, side angle, side angle, side angle, side angle, side angle); The angle between the two sides is equal ASA (angle side angle, angle, edge, angle; angle; angle side angle; angle side angle; angle side angle; angle side angle; angle side angle); Two corners and one clip edge): two corners with equal clip edges AAS (angle angle side, angle, edge; angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side, angle side; Two corners, one pair of sides): two corners, and the non clamped edges are equal RHS (right angle hypotenuse side), also known as HL (right angle hypotenuse side); In a pair of right triangles, the hypotenuse is equal to the other right side2. 2010 kart K1 champion 2010 kart K1 champion

6. Sick sinus syndrome (SSS)
is caused by sinus pacing and / or sinus conction dysfunction, resulting in a variety of arrhythmias and secondary clinical symptoms Bed syndrome. Arrhythmias include sinus bradycardia, sinus atrial block and slow fast syndrome. Syncope is common in patients with slow fast syndrome. It is often inced by long R-R interval after sudden stop of tachyarrhythmia (mostly paroxysmal atrial fibrillation). It is caused by the inhibition of sinus node function aggravated by overspeed inhibition. The diagnosis can be made when arrhythmia and syncope occur simultaneously by ECG monitoring or Holter. The function of sinus node can also be measured by transesophageal atrial pacing. Although the normal value of sinus node recovery time (SNRT) is not equal in different age groups, SNRT ≥ 2S has definite diagnostic significance. After intravenous injection of atropine (0.04 mg / kg), the heart rate increased to more than 90 beats / min, which can be used to eliminate vagal hypersensitivity; For vasovagal syncope similar to SSS, positive tilt table test is a favorable support for the latter
another relatively rare subtype of SSS is fast slow syndrome. The pathogenesis of SSS may be related to acute sinus node dysfunction. Some people in China reported fast slow syndrome associated with paroxysmal supraventricular tachycardia and fast slow syndrome associated with paroxysmal atrial fibrillation respectively. Like the slow fast syndrome, the clinical manifestations are syncope after sudden termination of supraventricular tachyarrhythmia. The pathological basis is also the sinus node itself, but the prognosis is quite different. Fast slow syndrome is characterized by sinus arrest after rapid atrial rate. Radiofrequency ablation can eliminate arrhythmia and terminate symptoms. However, slow fast syndrome is characterized by slow sinus rhythm followed by rapid ectopic atrial rhythm and sinus arrest. Anti tachyarrhythmia drugs should be taken after implantation of al chamber, al chamber or permanent pacemaker with anti atrial fibrillation function.
