Insights
Children with atrial septal aneurysm show delayed P-wave duration and dispersion. This indicates electrical disturbance and an increased risk of atrial arrhythmia in these patients.
Area of Science:
- Cardiology
- Pediatric Electrophysiology
Background:
- Atrial septal aneurysm (ASA) is a condition affecting children.
- Understanding its impact on cardiac electrical activity is crucial.
Purpose of the Study:
- To investigate P-wave duration and P-wave dispersion in children diagnosed with ASA.
- To assess potential electrocardiographic risks associated with ASA.
Main Methods:
- A prospective controlled study included 41 children with ASA and 32 controls.
- P-wave dispersion was calculated using 12-lead electrocardiography.
- Echocardiography assessed cardiac function, aneurysm morphology, and left atrial diameter.
Main Results:
- No significant demographic or echocardiographic differences were observed between groups.
- P-wave dispersion was significantly prolonged in children with ASA (64.4 ± 13.4 ms).
- Maximum P-wave duration was also significantly longer in the ASA group (106.1 ± 13.3 ms).
Conclusions:
- P-wave dispersion is significantly delayed in children with atrial septal aneurysm.
- Prolonged P-wave dispersion suggests electrical disturbance.
- This finding indicates an increased electrocardiographic risk for atrial arrhythmia in pediatric ASA patients.
Background:
This was a prospective controlled study to determine the P-wave duration and P-wave dispersion in patients with atrial septal aneurysm.
Methods:
A total of 41 children with atrial septal aneurysm, including 21 boys and 20 girls (mean age 11.85 ± 3.8 years), and 32 controls, including 17 boys and 15 girls (mean age 12.3 ± 2.9 years), were included. P-wave dispersion was calculated from the 12-lead electrocardiogram. Cardiac functions, morphology of the aneurysm, and left atrial diameter were measured using conventional echocardiography. The diagnosis of atrial septal aneurysm was made when the base of the aneurysms with an excursion ratio ≥25% was found on echocardiography.
Results:
There was no significant difference between the patient and control groups in demographic, clinical findings, and M-mode echocardiographic parameters. The P-wave dispersion in patients with atrial septal aneurysm was significantly longer compared with the control group (64.4 ± 13.4 ms; p < 0.0001). Similarly, the the maximum duration of the P wave in the patient group was significantly longer compared with the control group (106.1 ± 13.3 ms; p < 0.001). The P-wave duration and dispersion were not correlated with age, gender, systolic and diastolic blood pressure, or m-mode echocardiographic parameters.
Conclusions:
This study shows that P-wave dispersion is delayed in atrial septal aneurysm patients. Prolonged P-wave dispersion was determined to indicate electrical disturbance, and therefore it has an increased electrocardiographic risk of atrial arrhythmia in children with atrial septal aneurysm.

The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
