1. Thoracic X-ray may reveal an enlarged heart, edema or pleural effusion were confirmed diagnosis of CHF.
2. ECG revealed tachycardia, hypertrophy and ischemic heart chambers, an echocardiogram.
3. Laboratory examinations include electrolytes, serum sodium levels were low expressed, resulting in hemodilution of blood from the excess water retention, potassium, sodium, chloride, urea and blood sugar.
4. Sonogram (echocardiogram) to indicate the dimensions of ventricular enlargement, changes in the function / structure of the valve or area decreased ventricular contractility.
5. Cardiac catheterization; abnormal pressure is an indication and help distinguish right and left heart failure and valvular stenosis or insufficiency. Also assess coronary artery patency. Contrast agent is injected into the ventricles shows abnormal size and ejection fraction / change contractility.
6. Ultrasonography (USG) image obtained free fluid in the abdominal cavity, and liver and spleen enlargement picture. Enlargement of the liver and spleen sometimes difficult checked manually when accompanied by ascites.
