Carotid Sinus Hypersensitivity (CSH) is a condition characterized by an exaggerated response to carotid sinus stimulation, leading to a variety of clinical manifestations. While syncope (fainting) is the most commonly recognized symptom, it is important to acknowledge the broad spectrum of clinical presentations associated with CSH. This article aims to shed light on the diverse manifestations of CSH, highlighting the importance of comprehensive evaluation and tailored management strategies. Syncope remains a hallmark symptom of CSH, occurring as a result of transient cerebral hypoperfusion due to carotid sinus stimulation. However, it is crucial to recognize that not all episodes of syncope are attributed to CSH, and other underlying causes should be considered. Evaluating the presence of typical prodromal symptoms, such as dizziness or presyncope, along with the occurrence of syncope during carotid sinus massage, helps establish the diagnosis [1,2].

Beyond frank syncope, CSH can manifest as presyncope or near-syncope episodes. Patients may experience lightheadedness, dizziness, or a feeling of impending faint, often triggered by specific activities or postural changes. These prodromal symptoms serve as crucial warning signs, enabling early intervention and prevention of syncope. In some cases, CSH can present as falls or drop attacks, where sudden loss of postural tone results in an unexplained collapse. These events may occur without loss of consciousness but are accompanied by a temporary loss of motor control. Recognizing this atypical manifestation is essential to avoid misdiagnosis and implement appropriate management strategies [3].


CSH can lead to persistent or recurrent dizziness and vertigo, mimicking other inner ear or central vestibular disorders. Patients may describe a spinning sensation or a sense of imbalance, often exacerbated by head movements or changes in posture. Identifying CSH as an underlying cause is crucial to provide targeted treatment and improve quality of life. While less common, CSH can present with a wide range of atypical symptoms, including palpitations, chest discomfort, shortness of breath, and even cognitive impairment. These manifestations may be attributed to the hemodynamic and autonomic disturbances induced by carotid sinus stimulation. A thorough evaluation is necessary to uncover the underlying etiology and prevent unnecessary investigations or interventions [4].


Beyond the classic presentation of syncope, Carotid Sinus Hypersensitivity encompasses a broad spectrum of clinical manifestations. Recognizing the diverse array of symptoms associated with CSH is crucial to ensure accurate diagnosis, appropriate management, and improved patient outcomes. A comprehensive evaluation, including a detailed clinical history, physical examination, and specialized testing, is essential to identify CSH as the underlying cause. Tailoring treatment strategies to address the specific clinical presentation of CSH enhances symptom control, minimizes morbidity, and improves the overall quality of life for affected individuals [5].
