P-wave amplitude and pulmonary artery pressure in scleroderma

N Wokhlu, VM Hsu, A Wilson, AE Moreyra… - Journal of …, 2006 - Elsevier
BACKGROUND AND PURPOSE: Scleroderma is an immune-mediated disease
characterized by excess deposition of collagen leading to microvascular occlusion.
Morbidity and mortality are often secondary to pulmonary hypertension from injury to
pulmonary microvasculature and interstitial lung disease. This study correlated P-wave
findings on the 12-lead electrocardiogram (ECG) with mean pulmonary artery pressure
(mPAP) measured by right heart catheterization in patients with scleroderma. METHODS: A …
