If RVS is found, the patient should always be referred for RHC. If RVS is not present, the serum concentration of NT-proBNP decides whether RHC should be performed. PAH can be ruled out with a probability verging on certainty in patients with no RVS and NT-proBNP levels \u2264 80 pg\/ml. RHC is therefore not required. Thus, by using an electrocardiogram and serum values of n-terminal natriuretic peptide, 90% of all exclusion catheterisations can be avoided without overlooking a single case of genuine pulmonary arterial hypertension [25].<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row fullwidth=&#8221;0&#8243; row_space=&#8221;remove_padding&#8221;][vc_column][gva_block_heading title=&#8221;ECG&#8221; align=&#8221;align-left&#8221;][\/gva_block_heading][vc_column_text] ECG has specificity of 70% and sensitivity of 55% in the diagnosis of PH [23].
