# What is Simiology?

## What is Simiology?

: the study of signs especially : semiotics.

## What does a Semiologist do?

semiology. The study of signs, symbols, and signals.

## What are 3 things a seismologist does?

Seismologists study earthquakes and their results, like tsunamis, and landslides. They may also monitor active volcanoes for tremors and signs of an impending eruption. They use seismographs and computer equipment to collect and analyze data on seismic events.

## What are the 2 types of surface waves?

The two types of surface waves are named Love waves and Rayleigh waves, after the scientists who identified them. Love waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of the two surface waves, Love waves move faster.

## What are the three types of waves?

One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves.

depolarisation

## Why S waves has a bigger wave?

S-waves cannot travel through liquids or gases. Because the earth’s mantle becomes more rigid as its depth below the asthenosphere increases, S-waves travel faster as they go deeper in the mantle….S-Waves.

S-waves travel through materials with rigidity and density
greater density slower S-waves

## What does P in AP Wave mean?

atrial depolarization

## What is another name for S wave?

In seismology, S waves, secondary waves, or shear waves (sometimes called elastic S waves) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.

## When P wave is absent?

Absence of the P wave with a flat baseline may indicate: Fine atrial fibrillation. Sinoatrial arrest (with a secondary escape rhythm)

## What is short PR syndrome?

The Lown-Ganong-Levine syndrome (LGL) is a clinical syndrome consisting of paroxysms of tachycardia and electrocardiogram (ECG) findings of a short PR interval and normal QRS duration.

## What is a normal P wave?

In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline. The amplitude is normally 0.05 to 0.25mV (0.5 to 2.5 small boxes). Normal duration is 0.06-0.11 seconds (1.5 to 2.75 small boxes).
