Key result
Inappropriate use of adenosine by paramedics for presumed PSVT occurred in 20% of cases, and was associated with initial heart rate <160 beats/min (p<0.001) and no history of PSVT (p=0.001).
Why the study?
What is the rate of rhythm misidentification by paramedics treating presumed PSVT with adenosine, and what factors are associated with inappropriate use?
Observational (n=224)
What is the rate of rhythm misidentification by paramedics treating presumed PSVT with adenosine, and what factors are associated with inappropriate use?
Paramedics misidentified rhythms in 20% of presumed PSVT cases treated with adenosine, with errors more common when the initial heart rate was <160 bpm or patients lacked a history of palpitations.

Paramedic adenosine use for presumed PSVT showed notable misidentification; leaves open questions on EMS training efficacy pending prospective studies.
Phillip J Goebel (2004) conducted an observational in Presumed paroxysmal supraventricular tachycardia (PSVT) (n=224). Paramedic treatment with adenosine for presumed PSVT was evaluated on Inappropriate use of adenosine (rhythm misidentification). Inappropriate use of adenosine by paramedics for presumed PSVT occurred in 20% of cases, and was associated with initial heart rate <160 beats/min (p<0.001) and no history of PSVT (p=0.001).
