Which symptom describes class II in the New York Heart Association classification?

Class II in the New York Heart Association (NYHA) classification describes patients with mild heart failure. Individuals classified in this category experience symptoms such as fatigue, palpitations, or dyspnea that occur with ordinary physical activity, but they can typically carry out daily activities without significant limitations.

This classification highlights that while symptoms do appear, they are not severe enough to prevent normal activity; rather, the individual feels comfortable at rest and during minimal exertion. As a result, the identification of Class II is crucial as it helps healthcare providers gauge the functional heart status of patients and tailor management accordingly. The distinction also aids in monitoring disease progression and treatment efficacy over time.
