|Myotonic Dystrophy 1 Sudden Cardiac Death|
This is a double-arm prospective observational study.
To be included in the study, DM1 patients had to have at least 18 years old, LVEF >35% on two-dimensional echocardiography, permanent pacing indication after non-invasive electrocardiographic evaluation or invasive EPS evaluation, according to the current guidelines. The following exclusion criteria were applied: electrolyte imbalance, thyroid disorders, prior cardiac surgery, prior cardiac arrest, prior spontaneous sustained ventricular arrhythmias, absuntion of antiarrhythmic drugs or medication known to affect cardiac conduction. All eligible DM1 patients underwent EPS for programmed ventricular stimulation; those in whom a sustained ventricula arrhythmia was inducible underwent subsequently ICD implantation. Non-inducible DM1 patients did not receive an ICD and underwent pacemaker implantation.
The primary endpoint was all-cause mortality. Secondary end-points were sudden death (SD), death due to cardiac arrhythmias, ICD interventions and arrhythmic events in implanted patients.

Positive EPS - ICD
Patients with inducible sustained ventricular tachycardia or ventricular fibrillation at EPS evaluation underwent ICD implantation
Negative EPS - PMK
All non inducible patients underwent PMK implantation
- All-cause mortality [ Time Frame: 24 months ]
