Cardiac Labs
This laboratory test measures hemoglobin, hematocrit and platelets and helps detect anemia or infection affecting exygen delivery.
What is a Complete Blood Count (CBC)?
These medications slow heart rate and decrease blood pressure by blocking betaadrenergic receptors.
What are beta blockers?
This pulse site is located at the 5th intercostal space at the midclavicular line.
What is the apical pulse?
This condition occurs when heart muscle becomes enlarged, thickened, or stiff.
What is cardiomyopathy?
These tests include PT, INR, and a PTT and are used to evaluate blood clotting ability.
What are coagulation studies?
This class of medications treats dysrhythmias by slowing sodium movement into heart cells.
What are sodium channel blockers?
The apical pulse is auscultated for this length of time in patients with dysrhythmias.
What is 1 full minute?
This occurs when the heart cannot pump enough blood to meet the body's needs.
What is heart failure?
These substances (such as sodium and potassium) affect cardiac electrical activity and can cause dysrhythmias when abnormal.
What are electrolytes?
These medications prolong repolarization of cardiac cells to stablilize heart rhythm.
What are potassium channel blockers?
These are the two normal heart sounds heard during auscultation.
What are S1 and S2?
This condition results from reduced blood flow to the heart muscle due to blocked coronary arteries.
What is myocardial infarction?
This cardiac marker rises within hours after heart muscle injury and is the most specific test for myocardial infarction.
What is troponin?
A common side effect of beta blockers is this slowed heart rate.
What is bradycardia?
This heart sound represents closure of the mitral and tricuspid valves.
What is S1?
This condition occurs when blood pressure remains consistently elevated.
What is hypertension?
This blood test evaluates cholesterol levels and helps determine risk for cardiovascular disease.
What are serum lipid tests?
Antisysrhythmic drugs are contraindicated in patients with this condition due to risk of worsening rhythm problems.
What is severe heart block or bradycardia?
This abnormal sound may indicate turbulent blood flow through a valve.
What is a heart murmur?
This life-threatening condition causes widespread clotting and bleeding siumltaneously.
What is disseminated intravascular coagulation (DIC)?
