381 Possible Causes for Exertional Syncope

  • Anemia

    Although many parts of the body help make red blood cells, most of the work is done in the bone marrow. Bone marrow is the soft tissue in the center of bones that helps form all blood cells. Healthy red blood cells last between 90 and 120 days. Parts of your body then remove old blood cells. A hormone called[…][]

  • Orthostatic Hypotension

    Childhood: Children with DBH deficiency have markedly reduced exercise capacity, perhaps because of hypotension engendered by physical exertion.[] The syncope associated with postural hypotension often suggests seizures and prompts trials of anticonvulsive medication despite lack of abnormalities on the electroencephalogram[]

  • Asthma

    Asthma is a chronic inflammatory disease of the airways characterized by airway hyperresponsiveness and reversible airflow obstruction. It is caused by a combination of incompletely understood environmental and genetic interactions. Common symptoms include wheezing, coughing and dyspnea, which may vary from mild[…][]

  • Hypertrophic Cardiomyopathy

    Clinical features Exertional syncope or pre-syncope — this is the most worrying symptom, suggesting dynamic LVOT obstruction ventricular dysrhythmia, with the potential for[] Syncope is very common, resulting from inadequate cardiac output with exertion or from cardiac arrhythmia. It occurs more commonly in children and young adults.[] If these patients present with symptoms (e.g. chest pain, exertional syncope) and have a characteristic HCM ECG (showing LVH and dagger-like Q waves), they need to be referred[]

  • Angina Pectoris

    A disorder characterized by substernal discomfort due to insufficient myocardial oxygenation. A heart condition marked by paroxysms of chest pain due to reduced oxygen to the heart. Angina is chest pain or discomfort you get when your heart muscle does not get enough blood. It may feel like pressure or a[…][]

  • Aortic Valve Stenosis

    Angina, exertional syncope, and heart failure are key symptoms indicating a need for intervention.[] Findings Angina, exertional syncope, and heart failure are key symptoms indicating a need for intervention.[] Other symptoms associated with aortic stenosis are angina (chest pain) and fainting upon exertion (syncope).[]

  • Aortic Valve Disorder

    Symptoms of aortic stenosis may include: Breathlessness Chest pain (angina), pressure or tightness Fainting, also called syncope Palpitations or a feeling of heavy, pounding[] , or noticeable heartbeats Decline in activity level or reduced ability to do normal activities requiring mild exertion Heart murmur It may be important to note that the person[]

  • Aortic Stenosis with Bicuspid Valve

    ), syncope (on exertion or at rest), and heart failure; exertional dyspnea is the most common complaint. 2,6 Manifestation of these symptoms most commonly occurs after age[] Exertional syncope in aortic stenosis: evidence to support inappropriate left ventricular baroreceptor response. Am Heart J. 1991;121(2 pt 1):603–606. 15.[] It can also cause syncope on exertion and even sudden death and so violent exertion should be avoided.[]

  • Subclavian Steal Syndrome

    Coolness or paraesthesia of the arm may occur either at rest of with exertion.[] ) Pain, paresthesia Pale, cool skin Weak, delayed radial pulse Disparity in BP 15 mm Hg Neurologic symptoms (rare) Dizziness, vertigo Ocular findings (e.g., diplopia ) Syncope[] Drop attacks (syncope) - fall to the ground without warning, temporary loss of consciousness with immediate recovery.[]

  • Mitral Valve Prolapse

    Historically, the term mitral valve prolapse syndrome has been applied to MVP associated with palpitations, atypical precordial pain, dyspnea on exertion, low body mass index[] , and electrocardiogram abnormalities (ventricular tachycardia), syncope, low blood pressure, headaches, lightheadedness, and other signs suggestive of autonomic nervous system[]
