Overview
Brief Summary
CRT and ICD has known as decreasing cardiac mortality in patient with heart failure. Especially, it has reported that CRT improved cardiac systolic function, quality of life of patients with heart failure. However, CRT and primary ICD was not generalized in Korea. So the investigators will register patients who implant CRT or ICD (primary), and follow them up. During scheduled follow up, all patients will perform echocardiography, 6 minute walking test, EKG, Holter monitoring and questionnaire on QOL.

Outcomes
Primary Outcomes
6 minute walking test
Time Frame: 12 month later afer enrollment
for functional capacity
Transthoracic echocardiography (TTE)
Time Frame: 12 month later afer enrollment
EKG
Time Frame: 12 month later after enrollment
for Ventricular arrhythmia events
NYHA(New York Heart Association) evaluation
Time Frame: 12 month later after enrollment
For functional capacity - The New York Heart Association (NYHA) Functional Classification provides a simple way of classifying the extent of heart failure. It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regard to normal breathing and varying degrees in shortness of breath and/or angina.
Secondary Outcomes
- Cardiac MRI or Cardiac CT(12 month later afer enrollment)
- Questionnaire on Quality of Life(QOL) : EQ-5D-3L (Optional)(12 month later afer enrollment)
