Several minutes later, the paramedics arrived and found that his pants were a bit wet (he never understood why he urinated on himself), but he was awake and coversant to the ambulance attendants. They connected him to a limited lead II tracing and weren't sure what they were seeing (the report said "SVT vs VT?"), so he was administered 6 mg adenosine in the field. The patient noted the paramedics looked concerned after administering the medication. An ECG strip was recorded, seen below:

He was urgently transferred to the closest Emergency Room. Interestingly, upon arriving there, he felt much better. Here's his initial EKG on presentation:

P.S.: Another EKG tracing from the following morning, in case you're wondering, can be found here.
