Relationship between J wave and ventricular tachycardia in patients with acute myocardial infarction

Objective: To observe the influence of J wave on ventricular tachycardia in patients with acute myocardial infarction.Methods: The electrocardiogram of 113 patients who were hospitalized less than six hours was retrospectively analyzed.The patients were divided into J wave group(43 cases) and non J wave group(70 cases).The static electrocardiogram of the two groups was recorded and the ventricular tachycardia rates were compared.Results: Ventricular tachycardia rates were significantly higher in the J wave group than in the non J wave group(P<0.05).Conclusions: The ventricular tachycardia rate is increased in patients with acute myocardial infarction accompanied by J ware,indicating that their electrocardiogram is more likely to be unstable.
