Study of arrhythmia is some Egyptian children using different non-invasive techniques

ABSTRACT

This study was conducted on 10 patients who presented with different types of arrhythmias detected on routine 12 lead ECG and long strip lead II. Their ages ranged from 8d. to 12 y. They were 6 females and 4 males. All of them had been subjected to good history taking and full clinical examination, standard 12 lead ECG with long strip leadll, Echocardiography and Holter monitoring. It was found that 80 percent of the cases had acute onset of symptoms, Dysponea and syncope were the presenting symptoms in 30 percent and 20 percent respectively, while 10 percent [one case] was symptomless. There was [negative] family history in all the cases [negative] consanguinity in 70 percent and normal perinatal history in 60 percent. Clinical examination revealed tachycardia in 40 percent and bradycardia in 20 percent normal blood pressure in all the cases, cardiomegally in 30 percent and congestive heart failure in 20 percent. Echo showed normal heart anatomy and diminsions in 60 percent cardiomyopathy in 2 cases, one case with Fallot's tetraology and RV enlargement in 4 cases. ECG showed that 3 cases had S.V.T., 2 had premature ventricular contractions, 1 with sick sinus syndrome, 1 with ventricular tachydysrhytmia, 1 with 3rd degree heart block, 1 with wolf-Parkinson white syndrome and one with dropped beat. Holter 24 hours monitoring revealed the same findings as long strip ECG except for the case with dropped beat that proved to have No Abnormalities
