Final answer:
The best way to differentiate between patients with systolic CHF and diastolic CHF is by using echocardiography. Echocardiography is a technique that uses ultrasound to see an image of the heart and can provide valuable information about the functioning of the heart, including whether the patient has systolic CHF or diastolic CHF.

While a history and physical examination can provide some clues, an echocardiogram is the most definitive test to differentiate between these two types of heart failure. Other diagnostic tests such as ECG and chest x-ray examination may also be helpful, but echocardiography is considered the gold standard.
