Final answer:
The use of adenosine for the treatment of stable undifferentiated wide-complex tachycardia is false, as adenosine is not effective for ventricular rhythms and could worsen the condition. Other treatments should be considered for ventricular tachycardia, including antiarrhythmic drugs or defibrillation for arrhythmias like ventricular fibrillation.
Step-by-step explanation:
The statement that adenosine can be used for the diagnosis and treatment of stable undifferentiated wide-complex tachycardia when the rhythm is regular and the QRS waveform is monomorphic is actually false. Adenosine primarily works by slowing conduction through the atrioventricular (AV) node and can terminate tachycardias that involve the AV node, such as supraventricular tachycardias (SVTs). However, wide-complex tachycardias can be of ventricular origin, where adenosine is generally not effective and could potentially worsen the condition. In cases of wide-complex tachycardias, especially when the origin is uncertain, it is critical to evaluate the rhythm carefully and consider the use of other agents, or electrical cardioversion if the patient is unstable.
Treatments and diagnosis for ventricular tachycardia (which is often wide-complex) may involve the use of other interventions such as antiarrhythmic drugs or defibrillation. Defibrillators are commonly used in cases of life-threatening arrhythmias, especially ventricular fibrillation, and can restore a normal rhythm by delivering an electrical shock to the heart.
