MLA week 1

MLA week 1 ECG & Cardiac Conduction System

ECG ECG # Electrocardiogram = records the electrical impulses that occur in the myocardium during a cardiac cycle.
The SA node triggers an impulse, the atrial fibers produce an electrial change called a "__" wave P - wave
The heart is located in the "______" cavity Thoracic or chest cavity
The apex of the heart points towards the Left Hip
Give 5 examples why a dr. may order a ECG After a Myocardial infarction - Symptoms - due to prescribed medications - insertion of a pacemaker - heart condition
Atrioventrical valves tricuspid and mitral valves
5 major vessels Superior Vena Cava; Inferior Vena Cava; Pulmonary Artery; Pulmonary Veins; Aorta
3 Cardiac cells 1; Automaticity (initiates the impulse) 2; Conductivity (passes the impulse along) 3; Contractility ( reacts to the impulse)
When a cardiac cell is resting it is Polarised - resting
When an electrical impulse is recieved it is Depolarised - action
Once the pathway has been depolarised it is REpolarised - REcovery
What is the order of primary cardiac conduction SA nodes - VA nodes - Bundle of His (right and left) - Purkinje fibers
P wave After the SA node fires spontaneously, a wave of depolarization spreads through the Atria, creating a wave.
What happens immediately after the P wave There is a pause (as the impulse passes through the AV node) a straight line on the ECG
In the QRS complex - any wave above the baseline is called a "__" wave R wave
A negative deflection following an R wave is an "__" wave S wave
