ELECTROCARDIOGRAM |
|
An electrocardiogram (ECG or EKG, abbreviated from the German Elektrokardiogramm) is a graphic produced by an electrocardiograph, which records the electrical voltage in the heart in the form of a continuous strip graph. It is the prime tool in cardiac electrophysiology, and has a prime function in screening and diagnosis of cardiovascular diseases.

ELECTROPHYSIOLOGY |
|
Electrophysiology is the study of the electrical properties of biological cells and tissues. It involves measurements of voltage differences across cell membrane, and studies of how the flow of electrical current across membranes is regulated. In neuroscience, it includes measurements of the electrical activity of neurons, and particularly action potential activity.

INTERNAL MEDICINE |
|
Doctors of internal medicine ("internists") focus on adult medicine and have had special study and training focusing on the prevention and treatment of adult diseases. At least three of their seven or more years of medical school and postgraduate training are dedicated to learning how to prevent, diagnose, and treat diseases that affect adults. Internists are sometimes referred to as the "doctor's doctor," because they are often called upon to act as consultants to other physicians to help solve puzzling diagnostic problems. While the name "internal medicine" may lead one to believe that internists only treat "internal" problems, this is not the case. Doctors of internal medicine treat the whole person, not just internal organs.

PHYSICAL THERAPY |
|
Physical therapy (also known as physiotherapy) is an allied health profession concerned with the assessment, diagnosis, and treatment of disease and disability through physical means. It is based upon principles of medical science, and is generally held to be within the sphere of conventional (rather than alternative) medicine. Physiotherapy is practiced by physiotherapists (also known as physical therapists, e.g. in the United States), though aspects may also be practiced under supervised delegation by physiotherapy assistants or other health professionals.
