100
What does PVC stand for?
Premature ventricular contractions.
100
Define ventricular tachycardia.
A fast, abnormal heart rate. VT is defined as 3 or more heartbeats in a row, at a rate of more than 100 beats a minute.
100
What are the 2 abbreviations for ventricular fibrillation?
VF and V-fib.
100
Define asystole.
The state of total cessation of electrical activity from the heart, which means no tissue contraction from the heart muscle and therefore no blood flow to the rest of the body.
100
What is the location of all of these rhythms?
Ventricles.
200
Define PVC's.
A type of abnormal heartbeats, extra heartbeats that disrupt your regular heart rhythm.
200
What are a couple of symptoms of ventricular tachycardia?
Fast heartbeat or a fluttering feeling in the chest (palpitations), Dizziness, Lightheadedness, Chest pain, Neck tightness, Shortness of breath, Fainting, Cardiac arrest.
200
Define ventricular fibrillation.
A heart rhythm problem that occurs when the heart beats with rapid, erratic electrical impulses.
200
What are a few symptoms of asystole?
Loss of consciousness, not breathing, and no pulse. Before asystole occurs some symptoms include chest discomfort, shortness of breath, weakness, and tachycardia.
200
What rhythm does the image above show?
Asystole.
300
What are a few symptoms of PVC's?
Futtering, dizziness, pulsing sensations, feeling a skipped or extra heartbeat.
300
Is there treatment for ventricular tachycardia? If so, name them.
No treatment is needed if, you don’t have underlying heart disease, you are not having difficult symptoms, or your VT episodes don’t last a long time. If you do have symptoms, your healthcare provider might prescribe medicine (a beta-blocker or antiarrhythmic medicine) to control your heart rhythm.
300
What are the symptoms of ventricular fibrillation?
Chest pain, dizziness, palpitations, fatigue, etc.
300
What are some complications of asystole?
Fractured ribs, lung, and abdominal organ injuries, and abdominal/chest pain.
300
What rhythm does the image above show?
Ventricular fibrillation.
400
Do most people know if they are experiencing PVCs?
No.
400
Are there always symptoms present in all cases of ventricular tachycardia?
No, in some cases, there are no symptoms at all.
400
Is ventricular fibrillation deadly?
Yes.
400
Is asystole acute or chronic?
Acute, occurring after the sudden onset of cardiac arrest.
400
What rhythm does the image above show?
Ventricular tachycardia.
500
What are the ECG changes in cardiac monitoring for PVC's?
The ECG can detect the extra heartbeats and identify the pattern and source, these can be detected by seeing premature and long QRS complexes, they are not followed by a P wave and the T wave is large and in an opposite direction of the QRS.
500
What are some complications of ventricular tachycardia?
Some people may have mild symptoms from VT or no symptoms at all. But for others, VT can be very dangerous. It can lead to sudden cardiac arrest and death
500
What are the ECG changes in cardiac monitoring for ventricular fibrillation?
Begins with ventricular tachycardia and appears as a very irregular rhythm with indiscernible P waves or QRS complexes on ECG. Preceded by ventricular flutter which has rapid sinusoidal QRS complexes that can not be distinguished from T waves.
500
What are the ECG changes in cardiac monitoring for asystole?
No electrical current is present, so no changes are shown on the monitor. It is a flatline with no P waves or QRS complexes present.
