189 Possible Causes for Electrocardiogram Change, 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] In both types, characteristic electrocardiogram changes occur, and in later stages there is usually right-sided cardiac failure. cor pulmonale (kôr′ po͝ol′mə-nä′lē, -năl′ē[medical-dictionary.thefreedictionary.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]

  • Third Degree Atrioventricular Block

    There is a wide spectrum of changes in the resting electrocardiograms of athletes.[ncbi.nlm.nih.gov]

  • Right Atrial Hypertrophy

    For example, positioning leads V1 and V2 too high ( by 1 or 2 interspaces ) on the chest — may result in prominent P wave negativity, that in lead V1 might falsely suggest[ecg-interpretation.blogspot.com] Look for signs of atrial abnormalities in leads in which the P wave is most prominent: usually lead II, but also leads III, aVF, and V1.[medicine-on-line.com] Jugular venous pressure is elevated with a prominent systolic 'v' wave. Right ventricular impulse is hyperdynamic and may be thrusting in quality.[patient.info]

  • 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] Occasionally, a repeat electrocardiogram, chest X-ray, or echocardiogram is performed to further evaluate clinical changes.[downsyndrome.nacd.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]

  • Corrected Transposition of the Great Vessels

    ECG absence of Q waves in the lateral precordium (V4-6) physiologic Q waves in these leads often referred to as "septal" Q waves prominent Q waves in right precordium (V1-[radiopaedia.org]

  • 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] Findings: General EKG Changes suggestive of Coronary Ischemia Electrocardiogram may be completely normal ST Elevation or ST depression Over 1 mm ST changes that are transient[fpnotebook.com] R waves in V1-V3, R/S wave ratio 1.0 in lead V2, upright T-waves in V1-V3, often coexisting inferior or lateral MI.[errolozdalga.com]

  • Congenital Heart Block

    Abstract Congenital heart block (CHB) is a conduction abnormality that affects hearts of foetuses and/or newborn to mothers with autoantibodies reactive with the intracellular soluble ribonucleoproteins 48-kD La, 52-kD Ro and 60-kD Ro. CHB carries substantial mortality and morbidity, with more than 60% of[…][ncbi.nlm.nih.gov]

  • Hypokalemia

    prominent U waves require hospital admission.[physio-pedia.com] Oral replacement is preferred except when there is no functioning bowel or in the setting of electrocardiogram changes, neurologic symptoms, cardiac ischemia, or digitalis[ncbi.nlm.nih.gov] Treatments involve inducing potassium loss. 6-8 Electrocardiogram changes in hyperkalemia include a tall peaked T wave.[acls.com]

  • Hyperkalemia

    […] and width flattening or inversion U wave increased prominence rate, rhythm AV block, VF premature beats; tachyarrhythmias, torsades de pointes where: The P and T waves show[rccc.eu] changes in a nonadherent PD patient who was successfully treated with standard medical therapy and manual exchanges initiated by emergency department (ED) personnel.[ncbi.nlm.nih.gov] The most frequent causes of hyperkalemia in elderly patients are discussed and electrocardiogram changes and arrhythmias in hyperkalemia are analyzed, as well as their treatment[ncbi.nlm.nih.gov]

  • Cardiac Arrhythmia

    Ventricular fibrillation in a patient with prominent J wave in the inferior and lateral electrocardiographic leads after gastrostomy.[ncbi.nlm.nih.gov] Holter monitoring - This test is essentially a portable electrocardiogram, which records changes in heart rhythm as a person goes about daily activities.[midmichigan.org] A particularly dangerous arrhythmia, polymorphic ventricular tachycardia (in which there is a continually changing morphology of the electrocardiogram complexes), is probably[scholarpedia.org]
