32 Possible Causes for Exertional Syncope, Narrow Pulse Pressure

  • Anemia

    Class III (30-40% blood loss) always leads to a measurable decrease in blood pressure as well as significant tachycardia and a narrow pulse pressure.[emedicine.com] Class I ( Class II (15-30% blood loss) – Tachycardia, tachypnea, and a decreased pulse pressure are seen.[emedicine.com]

  • Aortic Valve Stenosis

    Signs Examination of the pulse in significant AS reveals a slow-rising, flat character called pulsus parvus et tardus. [ 7 ] Blood pressure will show a narrow pulse pressure[patient.info] Findings Angina, exertional syncope, and heart failure are key symptoms indicating a need for intervention.[doi.org] Clinical examination classically reveals a narrow pulse pressure, a slow-rising peripheral pulse, pulsus parvus et tardus (weak and delayed pulse) in the carotid pulse, a[radiopaedia.org]

  • 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[lifeinthefastlane.com] Syncope is very common, resulting from inadequate cardiac output with exertion or from cardiac arrhythmia. It occurs more commonly in children and young adults.[symptoma.com] 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[lifeinthefastlane.com]

  • Restrictive Cardiomyopathy

    Haemodynamic features delineated in the 1940s and '50s included the narrow pulse pressure in the right ventricle with normal systolic pressure and greatly increased diastolic[heart.bmj.com] He denied other associated diseases, except for syncope with permanent pacemaker implantation one year before the onset of symptoms of heart failure.[scielo.br] Syncope occurs occasionally, often exertional, reflecting the limited ability of the heart to increase diastolic filling and is an ominous sign.[circres.ahajournals.org]

  • Congenital Aortic Valve Stenosis

    Signs Examination of the pulse in significant AS reveals a slow-rising, flat character called pulsus parvus et tardus. [ 7 ] Blood pressure will show a narrow pulse pressure[patient.info] Findings Angina, exertional syncope, and heart failure are key symptoms indicating a need for intervention.[doi.org] Clinical examination classically reveals a narrow pulse pressure, a slow-rising peripheral pulse, pulsus parvus et tardus (weak and delayed pulse) in the carotid pulse, a[radiopaedia.org]

  • Rheumatic Aortic Valve Obstruction

    Clinical examination classically reveals a narrow pulse pressure, a slow-rising peripheral pulse, pulsus parvus et tardus (weak and delayed pulse) in the carotid pulse, a[radiopaedia.org] Untreated AS ultimately results in exertional syncope, angina, and dyspnea; sudden death may occur.[merckmanuals.com] Syncope on exertion, or effort syncope, occurs in aortic stenosis due to a sudden decrease in cerebral perfusion with physical activity.[healio.com]

  • Supravalvular Aortic Stenosis

    pulse pressure Electrocardiogram: Although aortic stenosis does not lead to any specific findings on the electrocardiogram (ECG), it still often leads to a number of electrocardiographic[checkorphan.org] Untreated AS ultimately results in exertional syncope, angina, and dyspnea; sudden death may occur.[merckmanuals.com] The patient was asymtomatic, referring fatigue on exertion and occasional syncope.[scielo.br]

  • Cardiac Tamponade

    pulse pressure and pulsus paradoxus may also be observed. 2 The diagnosis can be rapidly confirmed by bedside ultrasound. 3 In traumatic cardiac tamponade, the treatment[westjem.com] Cardiac tamponade often presents as a cardiogenic obstructive shock with shortness of breath, tachycardia, hypotension with a narrow pulse pressure (but blood pressure may[acls.com] […] with chest pain and respiratory distress. 2 Beck’s triad may be present on exam, as it was in our case: muffled heart sounds, distended jugular veins, and hypotension. 1 A narrow[westjem.com]

  • Congestive Heart Failure

    Signs There may be a tachycardia at rest, low systolic blood pressure (BP), a displaced apex (LV dilatation) or RV heave (pulmonary hypertension), a narrow pulse pressure[patient.info] A sensation that your heart is racing Wheezing and coughing Decreased appetite or loss of appetite Syncope Confusion Causes There are several types of heart failure and they[verywell.com] […] addition, when heart failure progresses to end-stage heart failure, additional symptoms are expected, including: Shortness of breath at rest Weakness and fatigue, even without exertion[verywell.com]
