Which of the following is a common symptom of Stokes-Adams disease?

Stokes-Adams disease, which is related to complete heart block, is characterized primarily by periods of syncope (fainting) caused by temporary lapses in the heart's ability to maintain an adequate rhythm. Severe dizziness is a common symptom during these episodes because the brain may not receive sufficient blood flow and oxygen due to the heart's ineffective pumping. This lack of blood perfusion can lead to feelings of lightheadedness or outright fainting.

While other symptoms, such as rapid heartbeat, chest pain, or nausea, may occur in various heart conditions, they are not specifically indicative of Stokes-Adams disease. The hallmark feature that sets it apart is the syncopal episodes associated with severe dizziness, caused by sudden drops in cardiac output during heart block. Recognizing this symptom is crucial for proper diagnosis and management of the condition.
