<u>ECG Risk Predication in ARVD</u></p>
<p>
Arrhythmogenic right ventricular dysplasia (ARVD) is a genetically determined cardiomyopathy characterized by fibrofatty replacement of the right ventricle (RV) predisposing to ventricular arrhythmias, heart failure, and sudden cardiac death (SCD).</p>
<p>
Twelve-lead electrocardiography (ECG) is an easily obtainable and noninvasive risk stratification tool for major adverse cardiac event (MACE); defined as a composite of cardiac death, heart transplantation, survived sudden cardiac death, ventricular fibrillation, sustained ventricular tachycardia, or arrhythmic syncope.</p>
<p>
ARVD ECG findings that predict adverse outcome are not well known.</p>
<p>
A multicenter, observational, long-term study, found ECG findings were quite useful for risk stratification of MACE, specifically:</p>
<p style="margin-left:.75in;">
- Repolarization criteria</p>
<p style="margin-left:.75in;">
- Inferior leads T wave inversions</p>
<p style="margin-left:.75in;">
- Precordial QRS amplitude ratio of ≤0.48</p>
<p style="margin-left:.75in;">
- QRS fragmentation </p>
