Termination is a non-programmable function of the device needing ___ out of ___ slow beats

• A. 10/16
• B. 12/20
• C. 12/16
• D. 14/16

Answer: (C)

A device terminates tachyarrhythmia using a built-in, non-programmable counter that requires a fixed proportion of slower beats before delivering termination therapy. In this case, termination occurs when 12 of the most recent 16 beats are slow, meaning a clear majority shows the rhythm has slowed enough to safely terminate the tachyarrhythmia. This fixed threshold—non-programmable—keeps termination behavior consistent and helps avoid stopping on brief pauses or random slowings, while still not delaying termination too long in a sustained tachycardia. The other thresholds would either allow premature termination on brief fluctuations or delay termination too much, so 12 out of 16 is the appropriate standard.
