347 Possible Causes for Prominent A-Wave, Sudden Death

  • 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] In the United States, approximately 25,000 sudden deaths occur per year from heart failure associated with pulmonary emboli.[nursing.unboundmedicine.com] 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]

  • Eisenmenger Syndrome

    ECG of Eisenmenger syndrome Usually there is right ventricular hypertrophy with prominent P waves.[remedyland.com] There were 21 (13%) documented deaths, of which 8 (5%) were sudden death.[ncbi.nlm.nih.gov] Longstanding pulmonary hypertension may cause dissection, which may lead to sudden death or pulmonary hemorrhage often seen in patients with Eisenmenger syndrome.[ncbi.nlm.nih.gov]

  • 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] Sudden cardiac death.[patient.info] 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]

  • 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] Its significance when identified in families affected by sudden arrhythmic death syndrome (SADS) remains unclear.[lra.le.ac.uk] 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]

  • Third Degree Atrioventricular Block

    We recommend routine 24-h Holter monitoring screening and, when indicated, consideration of pacemaker implantation to reduce the high risk of sudden death phenomena in this[ncbi.nlm.nih.gov] In severe cases, syncope and sudden death occur.[symptoma.com]

  • Cardiomyopathy

    […] patients with severe outflow gradients; S3 gallop is common in children but signifies decompensated CHF in adults; S4 is frequently heard Jugular venous pulse revealing a prominent[emedicine.medscape.com] A thorough family history of juvenile sudden death, ventricular arrhythmias and ICD implants should always be sought.[ncbi.nlm.nih.gov] METHODS: Two cases of sudden cardiac death owing to ARVC were reported.[ncbi.nlm.nih.gov]

  • Hypokalemia

    prominent U waves require hospital admission.[physio-pedia.com] Potassium levels above 6,0 mmol/l cause peaked T waves, wider QRS komplexes and may result in bradycardia, asystole and sudden death.[escardio.org] BACKGROUND: African-American ancestry, hypokalemia, and QT interval prolongation on the electrocardiogram are all risk factors for sudden cardiac death (SCD), but their interactions[ncbi.nlm.nih.gov]

  • Hypertrophic Cardiomyopathy

    […] patients with severe outflow gradients; S3 gallop is common in children but signifies decompensated CHF in adults; S4 is frequently heard Jugular venous pulse revealing a prominent[emedicine.com] Measured risk factors for sudden death included family history of sudden death, massive left ventricular hypertrophy, nonsustained ventricular tachycardia on Holter monitoring[ncbi.nlm.nih.gov] In addition, sudden death research in Dr.[mayo.edu]

  • Brugada Syndrome

    In patients with BrS, conduction delay in the right ventricular outflow tract (RVOT) causes a prominent R wave in lead aVR.[ncbi.nlm.nih.gov] Antiarrhythmic drugs like amiodarone and beta-blockers do not prevent sudden death in symptomatic or asymptomatic individuals.[doi.org] Surface ECG measurements showed less prominent J waves in Hey2 /- mice compared with wild-type.[ncbi.nlm.nih.gov]

  • Myocardial Infarction

    Lateral MI explains the presence of prominent R wave (R S) in V1. Ann Noninvasive Electrocardiol. 2015 ; 20 :570–577. doi: 10.1111/anec.12260.[circ.ahajournals.org] The primary outcome was the composite of sudden death or death from ventricular tachyarrhythmia at 90 days (arrhythmic death).[ncbi.nlm.nih.gov] Here, a rare case of sudden death due to tuberculous coronary arteritis with tuberculous coronary thrombosis resulting in acute myocardial infarction is presented.[ncbi.nlm.nih.gov]
