Which of the following is NOT a sign of bradyarrhythmia?

Tachycardia, characterized by a heart rate that exceeds the normal resting rate, is not considered a sign of bradyarrhythmia. Bradyarrhythmia itself refers to a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute in adults. In the context of bradyarrhythmia, patients may present with various symptoms and signs that are related to decreased cardiac output, including hypotension, ischemic chest discomfort, and signs of shock. These signs arise due to the heart's inadequate ability to pump blood effectively, leading to reduced perfusion to vital organs.

In contrast, tachycardia indicates a faster heart rate and does not align with the definition of bradyarrhythmia. Thus, it is clear why tachycardia is not a sign associated with this condition. Understanding this distinction is essential for accurately diagnosing and managing various arrhythmias in clinical practice.
