<prompt> NADAs criteria are used forAssessment of child for degree of dehydrationAssessment of child for degree of malnutritionAssessment of child for presence of heart diseaseAssessment of child for degree of mental retardation  <response>: The assessment of a child for the absence or presence of Heart disease can be done with the help of some guidelines suggested by NADA and are called NADAs criteria.NADAs CriteriaEither one major or two minor criteria are necessary for indicating the presence of heart disease.A Major Criteria1 Systolic murmur of grade III or more.The systolic murmur is classified into : -Ejection systolic murmurPansystolic murmurPansystolic murmur is always abnormal no matter what is its intesity.Only three lesions produce pansystolic murmur i VSD ii MR iii TREjection systolic murmur, on the other hand, may be organic or functional. an If ejection systolic murmur is associated with thrill, it is always organic.If ejection systolic murmur is more than grade III intensity It is organic.Grade III or less ejection systolic murmur of a functional type may be heard in anemia or high fever in otherwise normal children.2 Diastolic murmurPresence of diastolic murmur always indicates the presence of organic heart disease.There are two exceptions.Severe hypertension Reduction of BP may cause an AR murmur to disappear.Anemia May result in delayed diastolic murmur across the tricuspid and mitral area.3 CyanosisCentral cyanosis indicates the presence of heart disease if lung disease has been excluded.4 CHFPresence of CHF indicates the presence of heart disease except in neonates and infants who get CHF from causes such as hypoglycemia and anemia.B Minor criteriaSystolic murmur less than grade III in intensity.Abnormal second heart soundAbnormal S2 always indicates the presence of heart disease.It has been included as a minor criterion only because auscultation is an individual and subjective finding3 Abnormal ECGThe main value of ECG lies in determining the : -Mean QRS axisRight or left atrial hypertrophyRight or left ventricular hypertrophy4 Abnormal X-ray If there is cardiomegaly in a good inspiratory film, it is highly suggestive for the presence of heart disease.5 Abnormal BP
