The Heart Failure Society of America has released new guidelines recommending cardiac resynchronization therapy for patients with mild heart failure symptoms. CRT is particularly recommended for patients in sinus rhythm with QRS duration greater than or equal to 150 ms with no right bundle branch block, who still suffer from severe left ventricular systolic dysfunction and functional class II to III symptoms despite getting optimal medical therapy. The updated guidelines were published in the Journal of Cardiac Failure.
