In this rhythm, the conduction pathway is the same as that in sinus rhythm but the SA node fires at a rate less than 60 beats/minute
What is sinus bradycardia
100
syndrome characterized by decreased tissue perfusion and impaired cellular metabolism
What is shock
100
Metabolism changes from aerobic to anaerobic
What is initial stage
100
These patients present with tachycardia, hypotension and narrow pulse pressure
What is cardiogenic shock
200
HR is 150–220 beats/minute
What is SVT (supraventricular tachycardia)
200
The volume of blood in liters pumped by the heart in 1 minute.
What is cardiac output
200
Stage where the liver fails to metabolize drugs and waste
What is the progressive stage
200
Type of shock encompassing septic, anaphylactic and neurogenic
What is distributive shock
300
A rhythm characterized by recurring, regular, sawtooth-shaped flutter waves that originate from a single ectopic focus
What is atrial flutter
300
Results when fluid volume moves out of the vascular space into extravascular space (e.g., intracavitary space); also called third spacing
What is relative hypovolemia
300
This stage has profound hypotension and hypoxemia where one organ failure affects others
What is irreversible stage
300
The two types of shock that are classified as low blood flow
What is cardiogenic and hypovolemic
400
Characterized by a gradual lengthening of the P-R interval. It occurs because of a prolonged AV conduction time until an atrial impulse is nonconducted and a QRS complex is blocked (missing).
What is Mobitz I, Wenckebach
400
Brief lapse in consciousness accompanied by a loss in postural tone (fainting)
What is syncope
400
In this stage, baroreceptors in carotid and aortic bodies activate SNS in response to ↓ BP
What is the compensatory stage
400
Is an acute, life-threatening hypersensitivity (allergic) reaction
What is anaphylactic shock
500
AV dissociation in which no impulses from the atria are conducted to the ventricles
What is complete heart block (third degree)
500
represents a worsening stage of ischemia that is potentially reversible but may evolve to MI.
What is myocardial injury
500
Fluid moves into alveoli in this stage
What is the progressive stage
500
With this type of shock, patients will experience decreased CO, increased afterload and variable left ventricular filling pressure
