Ceiling Two Curtain Rods
in a procedure room of a hospital in the capital, we have the patient "Kela" with the following diagnoses:
1) pregnancy of 17 weeks.
2) dilated cardiomyopathy, ejection fraction 15%
4) single-chamber ventricular pacemaker. Dilated cardiomyopathy is a disease in which the heart weakens and becomes enlarged and can not pump blood efficiently. Can be caused by infections (HIV, Chagas disease), hypertension, autoimmune diseases, etc.
The ejection fraction (EF) is the percentage of blood that filled the left ventricle can eject the aorta at each systole (contraction). Its normal value is around 60%.
ejection fraction
normal  |
reduced ejection fraction
 | *
According to the cardiologist's assessment may require placement of a pacemaker, or an electrode that electrically stimulate the ventricles to contract at a normal rate. In this case the patient had a pacemaker ventricular intracavitary (unicameral).
This means that one electrode is inside (intracavity) the right ventricle (chamber) to stimulate the heartbeat (ventricular only) at an appropriate frequency.
The reason for the presence of Kela in procedure room is a change of pacemaker. It will put a bicameral (two chambers, atrium and ventricle).
Thus, stimulation of the atrium will cause it to shrink and so will improve cardiac output (volume of blood ejected by a ventricle in a minute), since that, advancing pregnancy, the circulating blood volume pregnant women increased significantly in a few weeks and will be valuable contribution of atrial contraction to maintain adequate perfusion of all organs of the body.
more so if it is a very weak heart.
