Waveform
Waveform
Waveform (/ˈweɪvˌfɔːrm/), in the field of medicine, refers to the shape and form of a signal such as the wave seen in an Electrocardiogram or Pulse Oximetry.
Etymology
The term "waveform" is derived from the English words "wave" and "form", which literally means the form or shape of a wave.
Definition
In medicine, a waveform is a graphical representation of a physiological event. It is used to monitor the condition of a patient and to guide treatment decisions. The shape, frequency, and amplitude of the waveform can provide important information about the patient's health status.
Types of Waveforms
There are several types of waveforms used in medicine, including:
- Sinusoidal Waveform: This is a smooth, periodic oscillation that is typically used in the field of Cardiology to represent the electrical activity of the heart.
- Square Waveform: This is a non-sinusoidal waveform that is used in Pacemakers to deliver electrical pulses to the heart.
- Sawtooth Waveform: This is a type of waveform that is used in Respiratory Therapy to represent the flow of air during breathing.
Related Terms
- Amplitude: The maximum extent of a vibration or oscillation, measured from the position of equilibrium.
- Frequency: The rate at which something occurs or is repeated over a particular period of time or in a given sample.
- Phase: The position of a point in time (an instant) on a waveform cycle.
- Pulse: A rhythmic beating or vibrating, often of sound waves or light waves.
