Cardiac function
Volume of blood ejected by the heart each minute
Cardiac output
Syncope means....
Fainting
Lab test:Allows the study of electrical activity in the heart muscle. Records impulsing
ECG
This lab is analyzed to determine the body’s ability to maintain acid base balance.
Arterial blood gasses
Delays impulse conduction through the av node to slow the heart rate. Increases the strength of force of myocardial contraction
Digoxin
The amount of blood remaining in a ventricle at the end of diastole
Preload
Patients primary reason for seeking medical Care is referred to as ....
Chief comlplaint
Provides continuous ECG monitoring for 24-48 hours
Holter monitor
A protein involved in in the contraction of muscles
Troponin
Acts as a vasodilator. Relaxes smooth muscles, decreases preload, afterload, BP, CO, and systemic vascular resistance.
Nitroglycerin
Amount of pressure the ventricles must overcome to eject blood volume
Afterload
The quickest way to count heart rate on a 6 second EKG strip
Count the R waves and multiply
Uses ultrasound to create images of the heart
Echocardiogram
Not a laboratory test , but is a non-invasive test to measure 02.
Pulse ox
A loop diuretic that can cause hypokalemia
Lasix
Contraction and relaxation of the heart make up one heartbeat called the ......
Cardiac cycle
Difference between the systolic and diastolic pressures
Pulse pressure
Assesses the presence of and severity of coronary heart disease by having the patient exercise during ECG monitoring. BP is assessed.
Stress test
A battery of tests that measure the most common serum lipids
Lipid panel
An ACE inhibitor that may cause angioedema
The SA node normally generates impulses at a rate of .....
60-100 bpm
PMI
Creates images of body structures without using radiation
MRI
A cardiac hormone released when ventricular dilation and stretch such as with heart failure occurs
B-Type natriuretic peptide (BNP)
Use this class of drugs cautiously
NSAIDS
