Implication

JTc-d >85 ms may aid SCD risk stratification in HFrEF; leaves open incremental value and requires prospective validation.

Does increased repolarization dispersion predict sudden cardiac death and ventricular tachyarrhythmia in patients with chronic heart failure and LVEF <= 40%?

Population

163 patients with chronic heart failure, specifically ischaemic (n=126) and idiopathic dilated (n=37) cardiomyopathy with left ventricular ejection fraction <= 40% diagnosed by left ventricular angiography.

Intervention

Measurement of repolarization dispersion (Bazett's formula rate-corrected JT-interval dispersion, JTc-d) from 12-lead surface ECG

Outcome

Sudden cardiac death and ventricular tachyarrhythmiahard clinical

Rate-corrected JT-interval dispersion >85 ms on a standard 12-lead ECG is a strong independent predictor of sudden cardiac death and ventricular tachyarrhythmias in patients with chronic heart failure and LVEF ≤40%.
