[|Human|] 94 y/o male ef 35% with hypotention. history of cad, 1st degree heat block and chf and a heart attack . My question is with the placement of ICD if the ef% increased would the hypotention improve?I have decreased energy, dizziness, tired all the time and bouts with depression. I still live at home by myself and still drive but in the last six moths I have noticed a decline in how I feel unable to do the normal things I like to do. My heart doctors has suggested the placement of a pacemaker to increase my quality of live. Would this improve the dizziness and weak tired feelings.
[|AI|]  Hello, Cardiac resynchronization therapy (CRT) significantly improves functional status, exercise duration, left ventricular (LV) ejection fraction, death from progressive congestive heart failure (CHF), and hospitalization for CHF in patients with moderate-to-severe CHF, an abnormal LV ejection fraction, and a QRS duration on the electrocardiogram of 120 msec or more. Studies have shown that ICD therapy significantly reduced all-cause mortality by 33% in patients with class II or III CHF, an abnormal LV ejection fraction, and a QRS duration on the electrocardiogram of 120 msec or more. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
