Hypothesis
This study aimed to explore orthogonal P wave morphology and its variations in healthy subjects.
Conclusion
Changes in orthogonal P wave morphology are common in healthy subjects and appear predominantly after the age of 50.
Supporting Evidence
- Type 2 P wave morphology was significantly more common after the age of 50.
- P wave duration increased with age, being longer in subjects older than 50.
- Minimal intraindividual variation of P wave morphology was observed.
Takeaway
As people get older, the shape of a specific part of their heart's electrical signal changes, which is normal and can help doctors understand heart health.
Methodology
120 healthy volunteers underwent 6-minute 12-lead ECG recordings to analyze P wave morphology.
Limitations
Some asymptomatic AF patients may have been included, and echocardiography data was not available.
Participant Demographics
60 men and 60 women, evenly distributed in decades from 20 to 80 years of age.
