P-wave dispersion : relationship to left ventricular function in sickle cell anaemia

P-wave dispersion: relationship to left ventricular function in sickle cell anaemia

BACKGROUND The prognostic implications of P-wave dispersion in patients with a variety of cardiac disease conditions are increasingly being recognised. The relationship between P-wave dispersion and left ventricular function in sickle cell anaemia is unknown. OBJECTIVE This study was aimed at evaluating the relationship between P-wave dispersion and left ventricular function in adult Nigerian...

Left ventricular performance in children with homozygous sickle cell anaemia.

Left ventricular performance was determined by echocardiography in 44 black children with homozygous sickle cell anaemia and a control group of 28 normal black children of comparable age. Statistically significant differences were observed between the children with sickle cell anaemia and the normal group in left ventricular ejection fraction (sickle cell anaemia group: 0-59 + 0.01 [mean + stan...

P-wave dispersion and left ventricular diastolic dysfunction in hypertension

Relationship between P wave dispersion, left ventricular mass index and blood pressure.

INTRODUCTION The study of arterial hypertension risk factors in children guarantees the establishment of health policies to avoid complications associated with this illness in the future. The highest values of P-wave dispersion during sinus rhythm are pointed as predictors of atrial fibrillation in adulthood since there is an association between arterial hypertension, P-wave dispersion and left...

Sickle Cell Disease and Sickle Cell Anaemia

Sickle cell haemoglobin (HbS) results from an autosomal recessively inherited mutation in which the 17th nucleotide of the beta globin gene is changed from thymine to adenine and the amino acid glutamic acid is replaced by valine at position 6 in the beta globin chain. [1, 2]Sickle cells have a reduced deformability and are easily destroyed, causing occlusion of the microcirculation and a chron...
