Single-syringe technique
Double-synring technique
Patients in this arm will receive adenosine in a single syringe, diluted with normal saline up to 20 ml. The dosage of adenosine is according to the recommendation of ACLS guidelines, which recommended 6 mg as the first dose and 12 mg as the subsequent dose if SVT can not be terminated by the first dose.
Patients in this arm will receive adenosine using a double syringe, the first syringe contains only adenosine and the second syringe contains only normal saline 20 ml. Both syringes are connected to each other, and to the patient's IV portal with a stopcock. The administration must be done by two nurses one after another, adenosine syringe is injected first, then follow by normal saline. The dosage of adenosine is according to the recommendation of ACLS guidelines, which recommended 6 mg as the first dose and 12 mg as the subsequent dose if SVT can not be terminated by the first dose.
