[Electrocardiography of high resolution in the diagnosis of arrhythmogenic dysplasia of the right ventricle].
To assess the diagnostic value of high resolution ECG in ARVD which is a rare and diagnostically difficult disease, cardiac micropotentials were evaluated in 32 pts with ventricular arrhythmias with LBBB pattern and right axis deviation. Typical ECG-, ECHO-, angiographic features of ARVD were found in 9 pts (mean age 36 y, VT 8 pts, MAS-5). Normal right ventricle (NRV) (Echo, Tc99) was seen in 23 pts (mean age 36 y, VT-14 pts, MAS-6). 25 healthy man (mean age 28 y) served as control (C).


RESULTS
[table: see text] Morphology of total QRS complex in pts with ARVD, comparing to NRV pts and C, was exceptionally characteristic: it was composed of high frequency notches seen not only as prolonged LP but also within fundamental QRS complex.


CONCLUSIONS
In pts with ARVD beside presence of LP, significantly prolonged TVAT and characteristic notches within QRS complex are observed, therefore the high resolution ECG is a promising method in noninvasive diagnosis of ARVD.
