Blood
In the clinical setting, blood pressure refers to this.
What is arterial pressure?
This is located between the left atrium and left ventricle.
What is the mitral (bicuspid) valve?
Part of the cardiac conduction system known as the pacemaker of the heart.
What is the SA node?
What the MA should do if a lead does not appear on an ECG tracing before repeating the tracing.
What is reconnect the wire?
The MA should do this if the patient develops shortness of air while the MA is recording the ECG.
What is notify the provider?
The strongest blood vessel that function by carrying blood away from the heart.
What are the arteries?
When the wall of the arteries constricts, increasing blood pressure is called this.
What is vasoconstriction?
This causes arrhythmia when elevated.
What are potassium ions?
This wave represents atrial fibrillation which is continuous fibrillatory waves between the QRS complexes.
What is the P wave?
This time period is captures by each small square on the ECG.
What is 0.04 seconds?
This is caused by obstruction of blood flow to the heart muscle.
What is myocardial infarction?
This valve prevents backflow of blood from the pulmonary trunk into the right ventricle.
What is the pulmonary semilunar valve?
Causes heart-related chest pain.
What is angina?
The MA should check this after the ECG has been recorded to ensure validity.
What is the standardization mark that is 10 mm high?
The MA should instruct the patient to do this if they are experiencing palpitations while wearing the Holter monitor.
What is press the event button?
This valve prevents blood from flowing from the aorta back into the left ventricle.
What is the aortic valve?
Blood pressure is greatest in the arteries during this time.
What is when the ventricles contract?
A high concentration of this can cause longer-than-normal heart contractions.
What are calcium ions?
The MA should do this if he/she notices frequent, regular spikes on the ECG tracing.
What is turn off nearby electrical equipment?
This differentiates sinus tachycardia from ventricular tachycardia.
What is sinus tachycardia has narrow QRS complexes?
Venules and arterioles are connected by this.
What are capillaries?
Term used to prevent blood from flowing backwards into the heart.
What is regurgitating?
The test that is utilized to measure the heart's conduction system during exercise, when the demand for oxygen is increase.
What is stress testing?
10 mm tall by 5 mm wide.
What is the size of a standard calibration box on the ECG?
This is the duration of the standard calibration box.
What is 0.2 seconds?
