What is the ventricular rate threshold for vtach?

• A. Above 100 bpm
• B. Above 120 bpm
• C. Above 150 bpm
• D. Above 200 bpm

Answer: (C)

Ventricular tachycardia (VTach) is defined by a rapid heart rate originating from the ventricles, typically exceeding a certain threshold. In clinical practice, VTach is generally identified as a sustained rhythm with a ventricular rate of over 100 beats per minute. The threshold for diagnosing VTach is commonly set at a rate greater than 100 bpm, but many references specify the rate as exceeding 120 bpm for it to be frequently characterized as VTach. However, the standard coding often considers rates above 150 bpm to signify a clear presence of tachycardia, categorizing it more distinctly as VTach. Choosing a threshold above 150 bpm is relevant because at this rate, the rhythm typically shows persistent characteristics associated with VTach, such as wider QRS complexes and a more stable rhythm that can have significant clinical implications. Recognizing this aggressive heart rate is crucial for diagnoses and treatment strategies.
