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.
When an arrhythmia causes the heart to beat too fast, the heart doesn't pump effectively. Specifically, there may not be enough time between heartbeats for the heart to fill with blood, causing blood to back up into the lungs. The increased pressure and fluid in the lungs results in the feeling of shortness of breath.
