The initial dose of adenosine for a 24-year-old female patient experiencing a regular narrow complex tachycardia with a rate of 192 bpm would typically be 6 mg administered as a rapid IV bolus.
Adenosine is a medication that slows down the electrical conduction in the heart, allowing for the identification and treatment of certain rhythm disturbances. It is commonly used for tachycardias caused by re-entry circuits in the heart.
It's important to note that adenosine is administered under medical supervision, and the specific dose may vary depending on the patient's condition and response to the medication.
