ECG + Endo + Autoanalysers Flashcards
Electrocardiogram
the pictorial representation of the electrical activity of the heart
Electrocardiograph
the machine that receives the electrical information through electrodes and converts this into a picture on a monitor screen
P-Wave
Atrial depolarisation
QRS Wave
Ventricular depolarisation
T-Wave
Ventricular repolarisation
What is Ann ECG used for?
evaluate cardiac dz differentiate a variety of different dz monitor during anaesthesia + sx routine evaluation documentation of data
When evaluating cardiac dz, the ECG is used for?
cardiac enlargement
arrhythmias
pericardial dz
The secrets to success in recording ECG:
px positioning
restraint
lead placement
standard px positioning for an ECG reading
right lateral recumbency
Where do you have the leads attach to on an animal
green/white on bottom legs
green/red on top legs
What do yo need to perform a goof ECG?
good contact electrodes to skin some units need to be grounded insulate px set sensitivity 1mv=1cm height set speed 22mm/sec or 50mm/sec
Px prep for ECG
clip and skin should be moistened with alcohol for a diagnostic test to pastes and gels for longer monitoring
Types of bench top auto analysers:
Quality Assurance
encompassing program for the monitoring and evaluation of the various aspects of producing laboratory results to ensure that standards of quality are being met.This will include running quality control and comparative tests
Quality Control
typically refers to commercial material prepared to mimic patient samples when run on specific pieces of equipment. The manufacturer provides the result to be expected if the machine is reading tests accurately.
