Prolonged ECG abnormalities in a subject with high altitude pulmonary edema (HAPE).

High Altitude Pulmonary Edema (HAPE) is an uncommon type of non-cardiogenic pulmonary edema. Few data are available regarding ECG abnormalities in patients with HAPE. They are usually slight and related to acute pulmonary hypertension. This paper describes a case of prolonged ECG abnormalities in a subject with HAPE, with no proven cardiac diseases. The Authors discuss the pathopysiological aspects of this kind of hypoxic-induced right ventricular overload with extensive T-wave negativity in precordial leads.
