Which of the following is NOT true about the use of b blockers in CHF?

b blockers are not used during an episode of acute hea failure as it deteriorates the condition. Dose of b blockers should be gradually increased in CHF because high dose may cause decompensation which leads to Acute Hea Failure. They are generally used in mild to moderate (NYHA class II, III) cases of dilated cardiomyopathy with systolic dysfunction. Beta blockers are contraindicated in acute decompensated hea failure. MC Beta blocker used in CHF is Carvedilol.
