Electrocardiographic Findings of Bossone et al with Prognostic Significance for a Patient with Primary Pulmonary Hypertension (PPH)

Description

Bassone et al identified electrocardiographic findings with prognostic significance for a patient with primary pulmonary hypertension (PPH). This can help to identify a patient who may require more aggressive management. The authors are from the University of Michigan in Ann Arbor and II Universita degli Studi in Naples.


 

Parameters:

(1) height of the p wave in lead II

(2) qR pattern in lead V1

(3) right ventricular hypertrophy by the WHO criteria
