Osteoarthritis And Osteoporosis Correlation Research

Obective To observe the effects of implantable cardioverter defibrillator ICD and antiarrhythmic on malignant ventricular arrhythmia , discuss the prevention of sudden cardiac death and safety.Methods In the 104 selected patients who have the indication class I and IIa, 26 patients received ICD (ICD group), and 78 patients receive drug treatment. Patients in the two groups had the similar clinical symptoms such as basic disease, EF, cardiac function, and cardiac arrhythmia, except that patients with syncope, CPR, and VF in ICD group were more than in drug treatment. Patients in the two groups received same basic therapy. 1years, 2 years, and 3years after patients were selected, the total death rate and the incidence rate of cardiac events of patients in the two groups were compared. Results During the observation time, in the selected 104 patients there was no death in the 26 patients in ICD group in 1years, 2 years, and 3years. The total death rate was 0. While in the 78 patients drug treatment group, 6, 14, and 17 patients died respectively in 1years, 2 years, and 3years, and the death rate was 7.69.%, 17.94%,, and 21.79% respectively. When observation time reached 3years, the death rate of patients in ICD group was lower than drug treatment group by 21.79%, the difference was considered statistically significant (P <0.05). 18(73.1%) patients in 26 ICD group, the storage data revealed that 469 episodes of nonsustained VT which spontaneously terminated. 265 episodes were sustained VT,245(92.5%) episodes treated by 1 ATP treatment succe -ssfully.13(4.89%) episodes treated by 2 ATP treatment successfull y, and 7(2.64%) episodes ATP treatment failed resort to low energy cardiov -ersion.41 episode were VF which 14 spontaneously terminated before discharged.36 VF episodes (87.80%) were terminated by 1 energy shocks.5 (12.2%) VF episodes were terminated by 2 energy shocks successfully.and compared with drug group they had similar ventricular arrhythmia incidence but VT/VF were terminated by energy cardioversion succes -sfullyin ICD group, to compare with drug group the incidence of ventricular arrhythmia ,The difference was considered statistically significant .Conclusions ICD group is better than drug group on the preventive effect of sudden cardiac death to the patients with heart disease complicating malignant ventri- cular arrhythmia,ICD can effectively stop malignant ventricular arrhythmia,decrease the incidence rate of sudden death and death rate, and improve the survival rate of patients. especially in the long term follow up patients. The layer function of ICD, VT can bet erminated effectivelly by antitachycardi apacing,Avoided and diminished ICD discharge,Relieved painess by defibrillator .and relived patiets economics load.
