[|Human|] I have a 95 year old mother that is suffering from congestive heart failure and atrial defiberation she takes medicine for high blood pressure. Her doctor said that she doesn t need a pace maker. What would be some of the reasons that he thinks she would not benefit from a pacemaker. I neglected to ask him that question.
[|AI|]  Hi every patient with CHF does not need a pacemaker there are some indications for peacemaking in a patient IOF congestive cardiac failure I am mentioning some of them, it depends on the stage of CHF and how well it is controlled by medicines, Thirty to 50 percent of patients with advanced congestive heart failure have major intraventricular conduction defects, CHF along with intraventricular conduction defect is an indication forpacemaking, especially complete left bundle branch block have been shown to be independent predictors of mortality. Delayed activation of the left ventricle as a result of left bundle branch block has been shown to produce significant synchrony in left ventricular contraction and relaxation. The synchrony can be minimized by biventricular pacing. So every patient with CHF is not helped by pacemaker, your mother must not be having stage 4 CHF and her interventricular conduction system would have been normal, so peacemaking is not required in her case
