A nurse is reviewing a client's cardiac monitor for dysrhythmias. Which of the following findings should the nurse identify as an indication for the placement of a permanent pacemaker?

Rationale: A. Vasovagal bradycardia without syncope: Vasovagal bradycardia, which is often caused by a reflex response to certain triggers, typically does not require a pacemaker. If the client is not experiencing syncope, a pacemaker is generally not indicated. B. Sinus tachycardia with rates faster than 80/min: Sinus tachycardia is generally not an indication for a pacemaker. A heart rate faster than 80/min is often a physiological response to various conditions, such as exercise or stress, and usually does not require pacing unless. C. Asymptomatic second-degree AV block: Asymptomatic second-degree AV block does not always require a pacemaker. Many individuals with this type of block do not experience significant symptoms, and treatment may not be necessary unless the block progresses. D. Complete AV block with rates slower than 40/min: A complete AV block with a heart rate slower than 40/min is a serious condition that often requires the placement of a permanent pacemaker. This type of block disrupts the normal conduction between the atria and ventricles, leading to slow heart rates and inadequate cardiac output.
