163 Possible Causes for Down Syndrome, Left Axis Deviation

  • Atrial Septal Defect

    McMahon, Congenital Heart Disease in Down Syndrome, Advances in Research on Down Syndrome, 10.5772/intechopen.71060, (2018).[doi.org] When an ostium primum atrial defect is present, the ECG reveals left axis deviation.[healio.com] In ostium primum ASD, it shows left axis deviation and right bundle branch block. In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III.[symptoma.com]

  • Ostium Primum Atrial Septal Defect

    Endocardial cushion defects are the most common congenital heart defect that is associated with Down's syndrome.[en.wikipedia.org] External links Down's Heart Group UK National charity related to heart conditions associated with Down's Syndrome.[ipfs.io] Pulmonary vascular obstructive disease may develop in a subset of patients—and those with Down syndrome are at the highest risk. [6] The prognosis is guarded, and morbidity[emedicine.com]

  • Endocardial Cushion Defect

    Down syndrome with endocardial cushion defect is a challenging diagnosis for parents as well as members of the health care team.[ncbi.nlm.nih.gov] Abstract Three groups of patients are identified in the series of secumdum atrial septal defect with left axis deviation in an analysis of 910 patients of secundum atrial[ncbi.nlm.nih.gov] Left axis deviation Biventricular hypertrophy Chest X-ray Cardiomegaly with increased pulmonary vascular markings Treatment Close the atrial and/or ventricular septal defects[echocardiology.org]

  • Hyperkalemia

    As seen with tumor lysis syndrome - when you receive chemotherapy, the drugs will act by breaking down the tumor cells.[chemocare.com] Left axis deviation. Absent P waves. Example 6 Hyperkalaemia: Sine wave appearance with severe hyperkalaemia (K 9.9 mEq/L). Example 7 Hyperkalaemia: Huge peaked T waves.[lifeinthefastlane.com]

  • Morbid Obesity

    I will always remember a little girl coming up to me in the grocery store – she was about 12 years old and had Downs Syndrome; she looked me in the eyes and said, “I’m sure[drmcdougall.com]

  • Heart Failure

    In AHF caused by acute coronary syndromes, nitrates are favoured over SNP as SNP may cause ‘coronary steal syndrome’. 77 , 78 10.3.3 Nesiritide.[doi.org] Electrocardiography demonstrated poor R-wave progression in leads V1-V3 with right axis deviation and low voltage criteria.[ncbi.nlm.nih.gov] Controlled trials with SNP in AHF are lacking and its administration in AMI has yielded equivocal results. 76 SNP should be tapered down to avoid rebound effects.[doi.org]

  • Ventricular Tachycardia

  • Atrioventricular Septal Defect

    We found only one reported case of congenital hypertrophic cardiomyopathy and atrioventricular septal defect in an infant with Down syndrome.[ncbi.nlm.nih.gov] Electrocardiography in patients with AVSD: QRS axis: Left-axis deviation is characteristic. Right-axis deviation occurs only in 3 %.[cardiologyforyou.blogspot.com] Nearly, 400 participants were included in the genetic association study and they were stratified as Down syndrome (DS) with atrioventricular septal defect (AVSD), DS without[ncbi.nlm.nih.gov]

  • Tricuspid Atresia
