The right answer is Electrocardiography (or Electrocardiogram).
In a typical plot, one can notice five characteristic waves. They are called P, Q, R, S and T. The illustration below shows what a normal electrocardiogram looks like:
* the P wave marks the depolarization during the contraction of the atria;
* the PR interval indicates the time required to transmit the electrical impulse of the sinus node of the atria to the ventricular muscles;
* the QRS complex marks depolarization and ventricular contraction;
* the QT interval corresponds to the global ventricular repolarization;
* T wave refers to the end of ventricular repolarization.
1.Job stability. According to the United States Bureau of Labor Statistics, the healthcare industry is projected to grow 18 percent from now until 2026, much faster than the average for all occupations. This projected growth is mainly due to an aging population and a greater demand for healthcare services. Plus, it doesn’t matter where you are in the world, there will always be people in need of help. In a shaky economy and world of uncertainty, having this much job security is a huge advantage.
2.Great pay and benefits. As of May 2017, the median annual wage for healthcare practitioners and technical occupations (such as registered nurses, physicians and surgeons, and dental hygienists) was $64,770 – almost double the median annual wage for all occupations. Typically, the more training you have, the better the wages will be. For example, the average base pay for a neurosurgeon is $489,839 per year.
3.Fast-paced workday. It’s likely that your career in healthcare will be highly stimulating with a constantly changing atmosphere (bye, bye 9-5 desk job). What your workday looks like depends on your specialty but be prepared to work face-to-face with patients and be on your feet most of the day. The medical field is full of excitement, and you’ll never live the same day twice.
4.Opportunities for growth. You don’t need years of medical training to make a difference in someone’s life. Some specialties only require a certificate, which could be achieved in a year or two. Plus, medical facilities are looking for people to work in all areas of care, like reception and administration. If you’re looking to work your way up, many companies also offer continued learning programs and tuition reimbursement.
5.The chance to help people. Those who work in the healthcare industry typically have a desire to make a difference. Whether you’re the surgeon who removes debilitating tumors or the receptionist who offers a friendly smile to a patient who just received a difficult diagnosis, you’re there for patients and families when they need it most. Plus, The American Psychological Association reports that finding meaning in your work can influence your life outside of work, has a long list of benefits (like increased motivation and personal fulfillment) as well as decreased stress.
