29 Possible Causes for Mesocardia, Normal Electrocardiogram, Right Axis Deviation

  • Corrected Transposition of the Great Vessels

    Left axis deviation is diagnostically important ; cause of this is abnormal location of AV NODE and its connection with ventricular conduction system.[] Laboratory investigations including haematocrit and electrolytes were normal.[] The chest X-ray showed mesocardia. He began to experience signs and symptoms of heart failure in 1992, with a systolic murmur audible over the left sternal border.[]

  • Mesocardia

    ECG showed sinus tachycardia with right axis deviation and abnormal wave pattern in all leads.[] The echocardiography showed a cardiac malposition with the heart in the middle of the thorax, the atria in concordance with the ventricles, the great vessels in the normal[] mesocardia — meso·car·dia … English syllables mesocardia — n. placing of heart in middle of thorax … Dictionary of difficult words mesocardia — ˌme]zōˈkärdēə, ˌmē], ]sō noun[]

  • Scimitar Syndrome

    The ECG shows right axis deviation and signs of right ventricular strain. The anomalous vein(s) cause a vertical scimitar shape on chest radiograph.[] The electrocardiogram showed left axis deviation and chest X-ray revealed cardiomegaly with pulmonary plethora.[] Figure 1 Preoperative Chest X-ray showed a dextroposition and mesocardia with scimitar vein.[]

  • Ebstein Malformation

    Right axis deviation and Right Bundle branch Block are frequently observed as well.[] The electrocardiogram showed normal sinus rhythm, dilation of the right atrium and right bundle-branch block. The chest X-ray film showed a CTR 0.95 (Figure 1).[] The present case report illustrates fetal echocardiographic clues to the diagnosis that include mesocardia and apically displaced attachment of the left-sided atrioventricular[]

  • Dextrocardia

    axis deviation.[] Fig. 2 A right-sided, 12-lead electrocardiogram shows normal axis and normal progression of R-wave amplitude in the precordial leads.[] […] containing back-references to 746.87 : Abdomen, abdominal - see also condition heart 746.87 Anomaly, anomalous (congenital) (unspecified type) 759.9 Asplenia 759.0 with mesocardia[]

  • Congenital Pericardium Anomaly

    In other cases the ECG may show typical findings such as right axis deviation, incomplete or complete right bundle branch block and poor R‐wave progression due to clockwise[] Her cardiac examination was completely normal. Her electrocardiogram showed poor R wave progression.[] […] tumours, kyphoscoliosis, abnormalities of the diaphragm. cardiac orientation - the base to apex orientation of the heart: levocardia - apex directed to the left of the midline mesocardia[]

  • Levocardia

    ECG ( Fig 1 ): Right axis deviation and right ventricular hypertrophy.[] Plain X-ray films of the chest and abdomen showed a normally located heart and a right-sided stomach ( Fig. 1 ). The electrocardiogram was normal with sinus rhythm.[] Other forms of cardiac malposition, including dextrocardia, mesocardia and criss-cross heart, with chest radiograph and CMR correlation, are also discussed.[]

  • Uhl Anomaly

    ECG: Normal sinus rhythm with Himalayan P waves, right bundle branch block, and right axis deviation.[] Chest X-ray showed cardiomegaly, whereas electrocardiogram showed a normal sinus rhythm with poor right ventricular (RV) forces.[] […] congenital (at birth) Holt oram syndrome Hypoplasia of cardiac vein, congenital Malposition of cardiac apex, congenital (at birth) Malposition of heart, congenital (at birth) Mesocardia[]

  • Situs Inversus

    Fig 1 shows the ECG with right-axis deviation of the P wave (negative in aVL and lead I and positive in aVR) and of the QRS complex indicating left to right activation, and[] […] with normal lead placement showed marked right axis deviation with negative p wave in lead aVL and I.[] Mesocardia, a midline heart is sometimes regarded as a fourth malposition.[]

  • Congenitally Uncorrected Transposition of the Great Arteries

    Electrocardiograph showed normal sinus rhythm, right axis deviation, tall P wave with right atrial enlargement.[] Asymptomatic women with unremarkable resting electrocardiograms, a normal exercise test, good left ventricular function and a pre-pregnancy aortic valve peak pressure drop[] […] descending branch and gives rise to a circumflex branch left coronary artery resembles a right coronary artery situs inversus Plain radiograph Chest radiographs may present with mesocardia[]
