The cardiovascular system includes the heart and blood vessels. The heart is a muscular organ that pumps blood through the body using rhythmic contractions. It has four chambers - two upper atria and two lower ventricles. The aorta and vena cava are the main arteries and veins that carry oxygenated and deoxygenated blood to and from the heart. Cardiovascular diseases like heart attacks can occur if blood flow to the heart is blocked, usually by a clot. Modern procedures like cardiac scans, pacemakers, and electrocardiograms can monitor heart health and detect issues. Maintaining a healthy lifestyle through diet, exercise, avoiding drugs and smoking can help prevent cardiovascular diseases.

It usually takes 45 minutes and it is done under local anesthesia. The pacemaker implant results and experience can vary from one person to another. Some people stay in the hospital overnight and others go home the same day.
