[The electrocardiogram in endomyocardial fibrosis].
OBJECTIVE
To detail the most common electrocardiographic findings on the endomyocardial fibrosis and to correlate with the ventricular form.


METHODS
One hundred patients with endomyocardial fibrosis (68 female) with ages between 5 and 64 years old (mean 34 years). According to ventriculographic aspect the patients were divided in three groups: group I--11 patients with predominant right ventricular compromise; group II--58 patients with biventricular involvement, but not necessarily similar in intensity; group III--31 patients with predominant left ventricular compromise.


RESULTS
On patients with predominant right ventricular compromise, the electrocardiographic pattern was of QRS complex of low voltage in the frontal plane, presence of incomplete right bundle block and QRS complex with low voltage and with qr or qs aspect in V1 contrasting with QRS complex of great amplitude on V2 and V3. Left anterior hemiblock, aspect of inactive area, and R waves of high voltage on left precordial leads were observed on patients with predominant left ventricular involvement.


CONCLUSIONS
The electrocardiogram of endomyocardial fibrosis, in spite of inespecific, may help in the identification of ventricular involvement.
