The tricuspid valve is in between which two chambers of the heart?
Right atrium and right ventricle
The Sinoatrial (SA) node
I have more than one P wave for each QRS and my P waves look sharp and jagged. Which rhythm am I?
Atrial flutter
What is the medical term for high blood pressure?
Hypertension
What should a patient do if they notice a skin rash from the electrodes of their Holter monitor?
Call the office
The bicuspid valve is in between which two chambers of the heart?
Slow heart rate, wide QRS complexes, absence of P waves
I am irregularly spaced and my P waves are indiscernable. Which rhythm am I?
Which type of artifact is caused by the patient moving and trembling?
Somatic tremor
How many electrodes are placed on a patient getting a stress test?
10
This heart valve is the most prone to leakage.
Mitral/bicuspid valve
What is the intrinsic rate of the Purkinje fibers?
20-40 bpm
My P waves are regularly spaced and my QRS complexes are regularly spaced. However, my ventricular rate is much slower than my atrial rate. Which rhythm am I?
Third degree AV block
To calculate the heart rate for atrial fibrillation, which method must be used?
6 second method
Describe a cardiac event monitor (what is it, how does it work, how is it used, etc.).
A cardiac event monitor is a type of continuous monitor that a patient wears for a maximum of 30 days. Data will be transmitted wirelessly to the cardiologist in live time.
Oxygenated blood from the lungs enters the left atrium via which blood vessel?
Pulmonary vein
On a PQRST graph, which waveform corresponds to ventricular repolarization?
T wave
Junctional rhythm
Name ALL of the precordial leads.
V1, V2, V3, V4, V5, V6
Name one reason why a nurse and EKG technician would need to immediately stop a patient's stress test.
Change in the ST segment, patient complains of chest pain, patient's gait becomes unsteady, blood pressure rises dangerously high or drops dangerously low, etc.
List the four chambers of the heart in the order that blood flows through them.
RA-->RV-->LA-->LV
A delay in the electrical impulse from the AV node to the ventricles will cause which interval to increase on a PQRST graph?
PR interval
My P waves are rounded and upright in lead II, but my rhythm is irregularly spaced. Which rhythm am I?
Sinus arrhythmia
