ACLS review
166. Explain how vagal maneuvers and adenosine may aid in the correct identification of a tachyarrhythmia?
The diagnostic value of vagal maneuvers and adenosine is to transiently slow ventricular rate so that the arrhythmia can accurately be identified
167. What should the health care provider do if the patient fails to respond to an initial dose of adenosine?
If the rhythm does not convert within 1 to 2 minutes, the health care provider should give 12mg of adenosine rapid IV push.
168. If a patient in symptomatic SVT fails to respond to adenosine, what are two calcium channel blockers may be considered?
Diltiazem and Verapamil
169. What is the dosing regimen for Verapamil when treating refractory SVT?
Verapamil 2.5 mg to 5 mg IV bolus over 2 minutes.
If there is no therapeutic response, repeated doses of 5 mg to 10 mg may be administered every 15 to 30 minutes to a total dose of 20 mg
Diltiazem, give a dose of 15 mg to 20 mg (0.25 mg/kg) IV over 2 minutes; if needed, in 15 minutes give an additional IV dose of 20 mg to 25 mg (0.35 mg/kg). The maintenance infusion dose is 5 mg/hour to 15 mg/hour, titrated to heart rate
