313 Possible Causes for Prominent A-Wave, Syncope

  • Atrial Septal Defect

    In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III.[symptoma.com] We present the case of a 44-year-old methamphetamine abuser who had a 3-month history of worsening fatigue and near-syncope.[ncbi.nlm.nih.gov] She described her syncopal episodes as typical for true syncope: episodes were 1) transient, 2) self-limited 3) leading to falling, 4) the onset was relatively rapid with[cardiovascularultrasound.biomedcentral.com]

  • Third Degree Atrioventricular Block

    We report a case of a patient with more than 30 years of repeated syncopes, always following food intake.[ncbi.nlm.nih.gov] Twenty-seven patients were alive at the end of the follow-up, i,e 6-15 years after admission to this Department on account of syncopal episodes or CHB.[ncbi.nlm.nih.gov] […] block, and neurocardiogenic syncope, The American Journal of Medicine, 98, 4, (365), (1995).[doi.org]

  • 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] Common presenting features are exertional dyspnea, lethargy, fatigue, exertional syncope and chest pain, peripheral edema, anorexia and right upper quadrant pain.[symptoma.com] 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]

  • 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] However, significant obstruction and consequent hypertrophy of the right ventricle can result in volume overload and the development of fatigue, dyspnea, and syncope.[symptoma.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]

  • Pulmonary Arterial Hypertension

    At admission, all patients presented with syncope, World Health Organization functional class IV, right-sided heart failure, and extremely severe hemodynamic parameters.[ncbi.nlm.nih.gov] Only then, patients note reduced performance, breathing difficulties, dizziness and syncopes.[symptoma.com] Patients with PAH have dyspnea, reduced exercise capacity, exertional syncope, and premature death from right ventricular failure.[ncbi.nlm.nih.gov]

  • Posterior Myocardial Infarction

    A common theory is that prominent R-waves may actually represent inverted Q-waves. 1,8 Interestingly, over a third of patients had prominent R-waves in either V1 or V2.[bjcardio.co.uk] […] severe" (complete atrioventricular block or sinotrial block with pauses) in half the cases and "unstable" (bradycardia below 50 beats/min; ventricular pause with or without syncope[ncbi.nlm.nih.gov] Depending on the dimensions of the infarcted area, patients may present with low cardiac output symptoms, such as lightheadedness, syncope, sweating, dyspnea.[symptoma.com]

  • Eisenmenger Syndrome

    ECG of Eisenmenger syndrome Usually there is right ventricular hypertrophy with prominent P waves.[remedyland.com] The patients usually present with cyanosis, erythrocytosis, clubbing of fingers, syncope, arrhythmias, bleeding disorders and anemia.[symptoma.com] In general by the time true Eisenmenger syndrome develops patients are already symptomatic with easy fatigue, dyspnea, chest pain and syncope being common 5 .[radiopaedia.org]

  • Early Repolarization Syndrome

    Early repolarization syndrome is a well-recognized idiopathic electrocardiographic phenomenon characterized by prominent J wave and ST-segment elevation predominantly in left[ncbi.nlm.nih.gov] Although these retrospective studies do justify a careful evaluation of persons with this electrocardiographic pattern, especially of those with syncope or ventricular arrhythmias[ncbi.nlm.nih.gov] The main finding is an elevation between the QRS and ST segments of over 1 millimeter above the baseline, as well as ST elevation with prominent T waves in at least two leads[symptoma.com]

  • 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 12-year-old boy presented acutely after an episode of syncope with perioral cyanosis.[ncbi.nlm.nih.gov] 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]
