Hypothesis
P wave dispersion is increased in patients with pulmonary stenosis.
Conclusion
P wave dispersion and p max are increased in pulmonary stenosis, correlating with the pressure gradient but not with atrial diameters.
Supporting Evidence
- P wave dispersion was significantly greater in the PS group compared to controls.
- The mean pressure gradient at the pulmonary valve was much higher in PS patients.
- There was no correlation between P wave dispersion and the diameters of the right and left atria.
Takeaway
This study found that kids with a heart problem called pulmonary stenosis have a longer time between heart signals, which could lead to heart issues.
Methodology
The study included 42 patients with valvular pulmonary stenosis and 33 healthy controls, measuring P wave duration and pressure gradients using echocardiography and ECG.
Limitations
The study had a relatively small sample size and focused only on a specific age group.
Participant Demographics
42 patients with pulmonary stenosis (35 males, 7 females, mean age 22.1 years) and 33 healthy controls (23 males, 10 females, mean age 23.8 years).
