What does a wide QRS indicate? -ANSWER-taking longer for the
ventricles to contract and they are probably not contracting in
synchrony
increased risk for mortality even if they have a normal HR
ventricular remodeling -ANSWER-results in disruption of the normal
myocardial extracellular structure with resultant dilation of the
myocardium and causes progressive myocyte contractile dysfunction
over time
cellular changes associated with ventricular remodeling -ANSWER--
hypertrophy (abnormal myocyte growth)
-intrinsic myocyte dysfunction
, -alteractions in gene expression (proteins)
-cell loss
-extracellular matrix remodeling
-Ca handling (within the myocyte)
-mitochondrial dysfunction (the heart has a lot of mitochondria
because a lot of processes are ATP dependent)
hypertophied heart -ANSWER-diastolic heart failure (filling)
concentric
HFpEF
EF>50%
dilated heart -ANSWER-systolic heart failure (contractility)
eccentric
HFrEF
EF<40%
what is the difference between pathological and physiological
hypertrophy -ANSWER-pathological - thickening of the wall but the
chamber size is reduced
physiological - can see this in pregnancy or exercise - thickening of the
myocardial wall but the chamber size is sitll the same
