45 Possible Causes for Impaired Exercise Tolerance, Prominent A-Wave

  • Cor Pulmonale

    On electrocardiogram, there was right axis deviation, p-pulmonale, features of right ventricular hypertrophy along with presence of prominent Q waves in leads II, III and[ijem.in] A wave Abnormalities of the chest or lungs, depending on underlying condition causing CP Soft or inaudible heart sounds Right ventricular impulse palpated along left sternal[tele.med.ru] The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[lifeinthefastlane.com]

  • Atrial Septal Defect

    In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III.[symptoma.com] Imaging The chest X-ray shows a dilated pulmonary artery, prominent pulmonary vascular markings, and enlarged right atrial and ventricular chambers in patients with significant[symptoma.com]

  • Pulmonary Hypertension

    […] for conditions that can produce pulmonary hypertension (murmurs, collagen disease, valve pathology, VTE, OSA, alcohol consumption, chronic respiratory disease) Examination prominent[lifeinthefastlane.com] […] capacity, reduce exercise tolerance, 87 induce iron deficiency, 24 and increase the risk of stroke. 88 If phlebotomy is performed, iron status should be monitored closely[doi.org] A prominent A wave may be observed in the jugular venous pulse. A right-sided fourth heart sound (S 4 ) with a left parasternal heave may be auscultated.[emedicine.medscape.com]

  • Eisenmenger Syndrome

    ECG of Eisenmenger syndrome Usually there is right ventricular hypertrophy with prominent P waves.[remedyland.com] Patients with pre-tricuspid shunts were older, had higher BNP concentrations and lower exercise tolerance compared to patients with post-tricuspid shunts.[ncbi.nlm.nih.gov] Right ventricular (RV) function was impaired in patients with atrial septal defects, with larger right ventricles, impaired systolic function and adaptation.[ncbi.nlm.nih.gov]

  • Patent Ductus Arteriosus

    Donohue syndrome, a rare autosomal recessive disorder, is associated with the mutation of the insulin receptor gene in the short arm of the 19th chromosome. It is very rare that a syndrome of insulin resistance resembles Donohue syndrome with patent ductus arteriosus. A 14-year-old girl, whose parents were[…][ncbi.nlm.nih.gov]

  • Pulmonary Valve Stenosis

    ECG of pulmonary valve stenosis Electrical axis deviation to right or right ventricular hypertrophy, prominent P wave.[remedyland.com] With increasing right ventricular hypertrophy, right ventricular compliance decreases with a resultant increase in end-diastolic pressure and with prominent a waves in the[emedicine.medscape.com] Significant pulmonic stenosis is characterized by a prominent jugular venous a wave and a right ventricular lift Myocardial infarction of hypertrophied right ventricle may[emedicine.medscape.com]

  • Congenital Heart Disease

    A and V waves Diffuse, displaced left ventricular impulse; palpable RV impulse Increased first heart sound; persistent splitting of second heart sound Systolic ejection-type[doi.org] Clinical Signs and Symptoms Observed in Normal Pregnancy Hyperventilation causing shortness of breath and dyspnea Brisk, full carotid upstroke with distended jugular veins with prominent[doi.org]

  • Pulmonary Arterial Hypertension

    Safe transition of patients with pulmonary arterial hypertension (PAH) from parenteral treprostinil to oral selexipag therapy in both inpatient and outpatient settings is described. There is a paucity of published data on how to safely transition patients to oral therapy in the event of complications and problems[…][ncbi.nlm.nih.gov]

  • Hypokalemia

    prominent U waves require hospital admission.[physio-pedia.com] Other electrocardiographic changes of hypokalemia include T wave depression and prominent U waves. Diff.Dx: A. Inadequate dietary potassium intake B.[enotes.tripod.com] Findings such as T-wave flattening or prominent U waves will result in hospital admission. [3] Other tests may include: arterial blood gas basic or comprehensive metabolic[physio-pedia.com]

  • Congestive Heart Failure

    In 893 patients aged from 40 to 102 years, we simultaneously recorded electrocardiogram, phonocardiogram, and jugular venous pulse wave.[ncbi.nlm.nih.gov] The impairment of exercise tolerance indicated by NYHA classification was markedly improved by PD for both groups.[ncbi.nlm.nih.gov] Numerous mechanisms unrelated to hemodynamic dysfunction may underlie impaired exercise tolerance in patients with chronic heart failure.[doi.org]
