Does the combination of NSVT and HRT detected by 24-hour Holter ECG improve risk stratification for serious arrhythmic events in patients with left ventricular dysfunction?
Heart rate turbulence improves the predictive accuracy of nonsustained ventricular tachycardia for identifying serious arrhythmic event risk in patients with left ventricular dysfunction.
HRT can facilitate the predictive accuracy of NSVT for identifying patients at risk for serious arrhythmic events in patients with LV dysfunction.
