Answer:
Pacemakers and Stents
Step-by-step explanation:
Technological advancements in the diagnosis and treatment of circulatory problems have improved the quality of life and survival rates for millions of people.
Two discoveries or technologies that help treat people with circulatory problems:
1. Pacemakers
Pacemakers are devices that are implanted in the chest to regulate the heartbeat. They are used to treat a variety of heart conditions, including arrhythmias, which are abnormal heart rhythms. Pacemakers work by sending electrical impulses to the heart, which help to keep the heartbeat regular.
2. Stents
Stents are small, mesh-like tubes that are inserted into narrowed or blocked arteries. They help to keep the arteries open and improve blood flow. Stents are used to treat a variety of conditions, including coronary artery disease, peripheral artery disease, and carotid artery disease.
