24 Chromosome Microarray analysis is a new, comprehensive chromosomal screening of embryos that examines all chromosomes for abnormalities.
A pacemaker is a small, battery-powered device that sends electrical signals to the heart to keep the heartbeat steady. Thin wires, called leads, carry the signals from the pacemaker to the heart. A pacemaker can prevent or reduce dizziness, fainting, and shortness of breath caused by a slow or unsteady heartbeat. Your chest may be sore where the doctor made the cut (incision) and put in the pacemaker. You also may have a bruise and mild swelling. These symptoms usually get better in 1 to 2 weeks.
Pacemaker syndrome is caused by atrial cannon waves a result of simultaneous atrial and ventricular contractions. This causes the blood runs the wrong way and the heart production falls. This condition causes by VVI pacemaker can be resolved by reprogramming the pacemaker or replacement for a dual chamber pacemaker.VVI pacemaker is not sufficient when the ventricles are not able to beat together in the cases of congestive cardiac failure and then dual chamber pacemaker is required.Possible problems during implementation of VVI pacemakers are: 1  collapsed lung. 2  infection.VI pacemaker is not sufficient when the ventricles are not able to beat together in the cases of congestive cardiac failure and then dual chamber pacemaker is required.
