CRT seems is pacing me 100 bpm
3 weeks in. HR is between 85 an 115 bpm since two-week interrogation. Puzzled. Doc says may need tweaking, but he did not tweak it! They are trying to make the two walls of left ventricle squeeze, it seems. But the speed selected probably suggests low volume of stroke, incomplete emptying prior to squeeze, or sluggish response on the part of heart muscle. Kinda wish I knew! Of course, improvement is typically gradual for this kind of sickness.
