The relationship between the change of QT dispersion and ventricular arrhythmia in patients with acute stroke was analyzed.

A total of 80 acute stroke patients treated at the People′s Hospital of Shouguang City from May 2016 to October 2017 were selected and 40 middle-aged and elderly health checkups who were examined in the same hospital during the same period were selected as the study subjects. According to the type of stroke, they were divided into two groups: group A (hemorrhagic stroke, 32 cases) and B (ischemic stroke, 48 cases). All 40 healthy subjects were included in group C. Three groups of electrocardiographs were given for detection, and two groups of stroke patients were monitored by electrocardiograph. Observed the difference of QT interval dispersion, the incidence of ventricular arrhythmia and the dispersion of QT interval in patients with acute stroke.

The QT interval dispersion in group A was significantly higher than that in group B and C (P<0.05). There was no significant difference between group B and group C (P>0.05). The incidence of ventricular arrhythmia in group A was higher than that in group B (P<0.05). The QT dispersion in patients with acute stroke in ventricular arrhythmia group was significantly higher than that in patients with acute stroke in the acute group, and the difference was statistically significant. Significance (P<0.05).

Patients with hemorrhagic stroke have a higher risk of ventricular arrhythmias. If patients with acute stroke are associated with an abnormal increase in QT interval dispersion, they should be alert to ventricular arrhythmias.
