Research on relationship between left ventricular hypertrophy of essential hypertension and complex ventricular arrhythmia

Objective To study the relationship between left ventricular hypertrophy(LVH) of essential hypertension and complex ventricular arrhythmia,in order to provide a basis for clinical diagnosis and treatment.Methods Four hundred and thirty-two patients with essential hypertension(all in accord with the 2005 revised edition of hypertension prevention and treatment guidelines in China),according to LVH and age,were divided into LVH,non-left ventricular hypertrophy(non-LVH) and age ≥ 60 years old,60-year-old.The color Doppler echocardiography(in accordance with the Society of American Echocardiography(ASE) recommended methods of measurement) and 24 h Holter monitoring were used in this study.Results Complex ventricular arrhythmia occurrence rate in LVH group was as high as 33.76 percent,significantly higher than 9.82% in non-LVH group;the incidence of in the ≥ 60-years old group were higher than those in the 60 years old group(P 0.01).The LVH and complex arrhythmia were often combined with ischemic ST segment changes.Conclusion The early active control of blood pressure in hypertensive patients is the key to reduce the occurrence of LVH,and prevention of ventricular complex arrhythmia,thereby reducing the occurrence of cardiac events.
