Electrophysiology (from Greek, ēlektron, "amber" [see the etymology of "electron"]; physis, "nature, origin"; and, -logia) is the study of the electrical properties of biological cells and tissues.

It involves measurements of voltage change or electric current on a wide variety of scales from single ion channel proteins to whole organs like the heart.

In neuroscience, it includes measurements of the electrical activity of neurons, and particularly action potential activity.

Recordings of large-scale electric signals from the nervous system, such as electroencephalography, may also be referred to as electrophysiological recordings.

They are useful for electrodiagnosis and monitoring.

Electrocardiography (ECG or EKG) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.

These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's electrophysiologic pattern of depolarizing and repolarizing during each heartbeat.

It is a very commonly performed cardiology test.

Emergency Medical Technician (EMT) and ambulance technician are terms used in some countries to denote a health care provider of emergency medical services.

EMTs are clinicians, trained to respond quickly to emergency situations regarding medical issues, traumatic injuries and accident scenes.

Under the British system and those that are influenced by it, they are referred to as ambulance technicians (often shortened to techs), while in the American system and its influenced countries, they are referred to as emergency medical technicians.

A test or examination (informally, exam or evaluation) is an assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs).

A test may be administered verbally, on paper, on a computer, or in a confined area that requires a test taker to physically perform a set of skills.

Tests vary in style, rigor and requirements.

For example, in a closed book test, a test taker is often required to rely upon memory to respond to specific items whereas in an open book test, a test taker may use one or more supplementary tools such as a reference book or calculator when responding to an item.

A test may be administered formally or informally.

An example of an informal test would be a reading test administered by a parent to a child.

An example of a formal test would be a final examination administered by a teacher in a classroom or an I.Q.

test administered by a psychologist in a clinic.

Formal testing often results in a grade or a test score.

A test score may be interpreted with regards to a norm or criterion, or occasionally both.

A paramedic is a healthcare professional, predominantly in the pre-hospital and out-of-hospital environment, and working mainly as part of emergency medical services (EMS), such as on an ambulance.

The scope of practice of a paramedic will vary between countries, but generally includes autonomous decision making around the emergency care of patients.

In some countries 'Paramedic' is a protected title and accountable to a professional regulatory body.
