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.
Other important or common causes of shortness of breath include cardiac tamponade, anaphylaxis, interstitial lung disease, panic attacks, and pulmonary hypertension. Cardiac tamponade presents with dyspnea, tachycardia, elevated jugular venous pressure, and pulsus paradoxus.
