Answer 1

Answer:

१) A cardiologist diagnoses and treats problems of the heart and blood vessels. These include: Heart attack. Heart failure.

२) A cardiologist is a doctor who specializes in treating diseases of the cardiovascular system — mainly the heart and blood vessels. In order to become a cardiologist, a physician must attend four years of medical school and an additional six to eight years of internal medicine and specialized cardiology training.

३) Most cardiac arrests occur when a diseased heart's electrical system malfunctions. This malfunction causes an abnormal heart rhythm such as ventricular tachycardia or ventricular fibrillation. Some cardiac arrests are also caused by extreme slowing of the heart's rhythm (bradycardia).29
