Final answer:
In a patient with unstable tachycardia and a wide QRS complex, synchronized cardioversion is a treatment option. The doses of synchronized cardioversion depend on the underlying rhythm and clinical condition of the patient.
Step-by-step explanation:
In a patient with unstable tachycardia and a wide QRS complex, synchronized cardioversion is a treatment option. The doses of synchronized cardioversion depend on the underlying rhythm and clinical condition of the patient.
In general, for unstable tachycardia with a wide QRS complex, an initial energy dose of 100 to 200 joules (J) should be used. If the initial dose is not successful, higher energy levels can be considered, ranging from 200 to 360 J.
It is important for the medical team, including the cardiologist, to assess the patient's status and determine the appropriate energy dose for synchronized cardioversion based on their clinical judgment and guidelines provided by professional societies.
