The Superior Vena Cava gets blood from... | the head and upper extremities |
What does the Pulmonary Veins function? | Carries High Oxygen blood; comes from the lungs and returns blood back to the left Atrium for circulation to body organs and cells. |
The term for Rapid Heart Beat? | Tachycardium |
Coronary Insufficiency ? | The Right and left coronary arteries supply blood to the heart. Flow is considered insufficient if it can not meet the needs of the heart |
What is the purpose of the conduction system? | is to initiate the heart beat and regulate the cardiac cycle |
Eptopic | is a adjective to a event or tissue occurring at a place other than normal location. Ectopic heart beats are generated from impulse originating some other place than the SA node |
Where is the SA node located | Upper Wall of the right Atrium |
What is the SA node Function | To generate the stimulus to make the heart beat |
Systole | The heart is contracting |
When the Patient heart beat slow they can suffer from.... | Syncope |
The heart is located | In the mediastium |
what is the function of the heart? | To pump sufficient amounts of blood to all of the cells in the body |
When does the U wave usually appear? | After the T wave |
What does Ischemia mean? | is reduced (ish) blood (emia). A condition of inadequate blood flow to a tissue. Ischemia to the heart can cause angina, and if present long enough, infarction. |
What are the Chest leads called? | Percordial leads |
The right leg electrodes show no cardiac information.. | and serves as a ground |
What could a broken cable wire cause.... | a wondering base line |
Mediastinum | is the space between the lungs in the chest cavity: hold the heart and other respiratory units |
Electrodes are plates for.... | that come between the patient and the current |
Where do the Augmented aVR leads go? | To the right Arm |
When the Myocardium is Stimulated ... | It contracts |
What is the Myocardium made of? | Muscle |
If a patient has there right arm amputated above the elbow where do you put the leads? | You put the leads on the upper part of the arm. |
If patient has amputation where do you put the leads? | The important thing is to put the leads the same corresponding location. |
Pulmonary Artery | is the artery that carries low oxygen blood:leaves the right ventricle and goes to the heart |
Normal Sinus Rhythm rate is | 60-100 beats per min-> each complex and normal in appearance |
Bradycardia means | the heart rate is below 60 beats per min |
Sinus Arrhythmia | can be cause by changes in Breathing |
Asystole | Is a flat line, associated with dealth |
Pulmonary Circulation | Circulation that goes to the heart's right atrium to the lungs where it is oxygenated and releases built up carbon dioxide |
If the heart bear fires ectopically means... | the stimulus to generate the heart beat does not occur in the SA Node |
Chordae Tendinea Means | Holds heart valve in place |
What is the faulty action valve closed? | heart murmur |
When a patient feel heart pain | due to an inadequate blood flow t the heart |
What is a MI | Myocardial infarct and occurs when the mycardial tissue suffer death to the area because of insufficient blood flow |
What is the difference between Agonal and Assystole on an EKG | Asystole is flat line, while Agonal is less than 20 beats per min |
How do you calculate the heart rate? on a ekg strip | Counting the complete complexes in 3, or 6 sec and multiply by 20 or 10 |
Electrocardiogram | is the recording or tracing of the EKG |
What is the Cardiac cycle? | is the beginning of the beat until the beginning of the next beat. |
How many leads are on EKG? | 10 are use 12 Lead EKG tracing |
What does the T wave | relaxation of the ventricles |
What is one major cause of Heart failure? | High Blood Pressure |
QRST Complex represents | one entire cardiac cycle |
