" The correct answer is SVT, or Supraventricular Tachycardia". It is any rhythm that originates above the ventricles and needs to be treated. This is common to children and also to healthy patients. One may experience palpitations, fatigue or chest pain that makes them unstable. An adult who has medical findings of SVT, he or she will be given adenosine to regulate the rhythm caused by SVT.
For adults, 6 mg of adenosine is given in a rapid IV push and if unsuccessful, the second dose of 6 mg will be followed. A rapid push that is near to the heart must also be done within 10 seconds for the medicine to take its effect and raising the left arm above the head will also give rapid delivery of adenosine.
