Why the study?
Does time-domain signal-averaged ECG accurately detect underlying heart disease and predict prognosis in patients with suspected arrhythmogenic right ventricular dysplasia?
Does time-domain signal-averaged ECG accurately detect underlying heart disease and predict prognosis in patients with suspected arrhythmogenic right ventricular dysplasia?
The presence of late potentials on signal-averaged ECG is highly specific for underlying structural heart disease, particularly ARVD, though their absence does not rule out the disease or the risk of sudden death.
No takes yet. Share an insight, caveat, or question.
Supports incorporation of signal-averaged ECG into ARVD evaluation; leaves open its prognostic impact and need for prospective validation.
Leclerco et al. (1993) studied this question.
