Clinical and electrocardiographic parameters; association with pulmonary hypertension.
| Parameters | Frequency (%) | χ 2 | P value | |
|---|---|---|---|---|
| Increased PAP (n = 26) | Normal PAP (n = 36) | |||
| Male gender | 12 (46.15) | 19 (52.78) | 0.265 | 0.797 |
| Female gender | 14 (53.85) | 17 (47.22) | ||
| Loud P2 | 23 (88.46) | 29 (80.56) | 0.4985a | |
| LVH | 12 (46.15) | 32 (88.89) | 13.382 | <0.001* |
| LAE | 9 (34.62) | 14 (38.89) | 0.118 | 0.794 |
| RVH | 13 (50.00) | 5 (13.89) | 7.883 | 0.005* |
* Statistically significant (2 sided), a Fisher's exact test, P2 = pulmonary component of second heart sound, LVH = left ventricular hypertrophy, LAE = left atrial enlargement, and RVH = right ventricular hypertrophy.
