PCR Flashcards
1
Q
Characteristics of myocardial cells
A
Excitability, automaticity, contractility and conductivity.
2
Q
The PR interval
A
The time the impulse takes to travel from the SA node through the internodal pathways in the atria towards the AV node. Should measure between 0.12 and 0.20
3
Q
Cardiac Arrest
A
Cessation of adequate cardiac output.
4
Q
Asystole
A
Myocardial conduction system internal cellular environment has deteriorated to the point that the energy required for sodium potassium pump to work is not available i.e. no action potential being generated.
5
Q
Ventricular Tachycardia
A
P wave if present not associated with a QRS, rhythm is regular and fast >100 with wide QRS.
Can have a pulse or be pulseless.
6
Q
Torsades de-points
A
A type of VT
