[Sustained monomorphic ventricular tachycardia in myotonic dystrophy].
Myotonic dystrophy is an hereditary multisystemic disease, characterized by slowly progressive myotonic atrophy of skeletic muscles. The heart is frequently affected with occurrence of arrhythmias and His-Purkinje system dysfunction and, less frequently, myocardial dysfunction. The surface ECG is the most sensible indicator of heart disease, and the most common electrophysiological finding is the prolongation of the H-V interval. Patients usually have few cardiovascular symptoms, but when present, the most frequent are: syncope, arrhythmias, atrioventricular block, congestive heart failure and sudden death. We present two patients with sustained monomorphic ventricular tachycardia as initial presentation of cardiac disease.
