The characters of electrocardiogram in patients with group i pulmonary arterial hypertension
Main Article Content
Abstract
Objective: We investigate the characters of electrocardiogram in patients with group 1 pulmonary arterial hypertension.
Method and Results: 45 patients with group 1 pulmonary arterial hypertension was measured the characters of electrocardiogram between September 2021 and October 2022. R wave amplitude in V1 were 9.2 ± 5.8 mm, P wave amplitude in D2 were 2.17 ± 1.05 mV, 66,7% of patients has right axis and 64,4% has qR in V1. Patients with WHO 3,4 has higher P wave amplitute than patients with WHO 1,2 (2.75 ± 1.13 mm versus 1.91 ± 0.92; p=0,01). qR in V1 occur more in patients with WHO 3,4 than patients with WHO 1,2 (92,8% so với 31,7%;p= 0,01).[1]
Conclusion: Electrocardiogram of patients with group 1 pulmonary arterial hypertension has commonly occurred the P wave amplitude > 2,5 mm in D2, qR in D2 and right axis. P wave amplitude in D2 and qR in V1 has prognostic value of WHO group.
