| Abstract | ||||
| Background: Electrocardiographic abnormalities are common in asthma. Atrial electromechanical delay (AED) was assessed atrial conduction properties and used to predict risks of arrhythmias in bronchial asthma using tissue doppler echocardiography. The aim of: this work was to assess AED using tissue doppler echocardiography in children with asthma. Methods: This case control study was carried out on 40 asthmatic children aged from 8 to 16 years old, both sexes, diagnosed with asthma, suggested by periodic symptoms of chest tightness, dysnea and wheezing responding to bronchodilator asthma therapy (case group) and 40 healthy children as (control group). History, physical examination, Conventional echocardiographic and tissue doppler assessment including atrial electromechanical delay and myocardial performance index (MPI) ws performed for both group. Results: The dimension of right atrium (RA), P-wave dispersion (PWD), isovolumic contraction time (ICT), isovolumic relaxation time (IRT), ET, MPI, right ventricular (RV) pulmonary atresia, intra-right atrial conduction time (IRCT) and inter-atrial conduction time (IACT) was significantly higher in the asthmatic group (p < 0.05). IRCT and IACT were significantly higher in the asthmatic group. There was a significant positive correlation between IRCT with age, severity of asthma, duration of illness, ICT and IRT while significant negative correlation between IRCT with PEFR. There was a significant positive correlation between IACT with Tricuspid S and MPI while significant negative correlation between IACT with PEFR. Conclusions: Asthmatic children were associated with higher RA dimension, impaired RV function, higher IRCT and IACT. There was a positive correlation between IRCT and PWD, PEFR and MPI. | ||||
