Abstract
|
|
Non-invasive risk stratification of the arrhythmic
events and sudden death in dilated cardiomyopathy patients should be considered a very
important topic because of the high incidence of arrhythmic death in these patients. We
studied 25 dilated cardiomyopathy patients with non-invasive variables, such as
echocardiography, Holter monitoring and late ventricular potentials, to evaluate the
relationship between major arrhythmic events and heart rate variability as well as
signal-averaged ECG. Some HRV indexes, such as LF/HF ratio, could improve the sudden death
risk stratification, while the maximum number of beats per run of non-sustained
ventricular tachycardia may also play a role. On the contrary, the number of VEB/h
correlated with non-arrhythmic events.
