Can it kill if your heart rate goes up when you are sick?
If your heart rate increases because of adrenaline (related to your emotional state) that is unlikely to kill you. There are some conditions, particularly ventricular fibrillation, in which increased heart rate can kill you, but in most forms of sickness, increased heart rate is not dangerous.
Should someone with atrial fibrillation have a exercise stress test or a thallium stress test?
If you are a patient currently in atrial fibrillation. Generally speaking an adenosine or lexiscan nuclear stress tests are usually the best options. The other medicated stress test is Dobutamine (both echocardiogram and Nuclear). You do not want to use Dobutamine on patients at risk to go into atrial fibrillation because it is a drug that can induce it. For patients that are in chronic atrial fibrillation dobutamine can be used but is not considered to be as diagnostic as a lexiscan or adenosine stress test. The reason being (and this goes or exercise stress tests as well) dobutamine is a heart rate dependent test. This means the closer the heart rate gets to the patients age predicted max HR the more accurate the test is at detecting heart disease. The assumption in this is that the patient is in a sinus rhythm. Myocardial oxygen demand correlates directly with patients HR when the patient is in sinus rhythm. If the patient is in atrial fibrillation that correlation with myocardial oxygen demand becomes much more cloudy thus reducing the sensitivity of an exercise or dobutamine stress test with patients in atrial fibrillation. Both lexiscan and adenosine eliminate HR demands in detecting CAD which makes them the best test for a.fib patients.
What can you do or not do with a defibrillator?
A defibrillator is used when the heart goes into an abnormal rhythm called Ventricular Fibrillation. A normal heart will have a certain rhythm. The upper chambers of the heart, known as the Atria. One chamber is called the Atrium. The lower chambers are the ventricles. Each chamber is connected by valves in the heart. The right side of the heart receives oxygen poor blood. It is pumped out to the lungs and oxygen rich blood is pumped out by the left side of the heart. The heart has it's electrical system which keeps it in rhythm. The atrioventricular node is the heart's pacemaker and controls the rhythm of the heart. During a cardiac arrest the lower chambers or the ventricles can begin to quiver. They are unable to pump oxygenated blood into the body. Most importantly they can pump blood to the brain. If this is not corrected quickly a person will die. A defibrillator will deliver a shock of electricity to the heart in order to stop the quivering of the ventricles and stablize the rhythm of the heart. When using a defibrillator you usually start with a lower shock and increase the strength of the shock if it is not working and fibrillation is not correcting itself. Basically it restarts the heart to return it to a normal sinus rhythm. A defibrillator cannot bring someone back to life if the heart has completely stopped for a period of time. Sometimes a defibrillator doesn't work because there is too much damage to the ventricles. An inferior wall M.I. is a heart attack that occurs at the back of the heart and usually destroys the ventricle. A defibrillator cannot correct this. Defibrillators can also be used if someone is experiencing Atrial Fibrillation. Generally the process is the same but the patient may be conscious. Atrial Fibrillation is not as serious as Ventricular Fibrillation but if it is not corrected the patient can develop blood clots or other complications.
What is an outpatient hospital?
that is where a patient goes first when he feels ill. or where a patient goes with an accident. Then the opd doctor will decide what to do.. he will either treat the patient and let him go home or refer him to the relevant speciality if needed.
How long is the quiescent period?
0.4 seconds, ventricular contraction is 0.3. It goes 1.A 2.D 3.B 4.C
What can early defibrillation do?
When a person is in cardiac arrest, the heart goes into a spasm. The electrical activity become "spastic" and a condition known as ventricular fibrillation results. The defibrillator delivers a controlled electric shock to the body to give the heart a chance to start again. It does not start the heart per se. Defibrillating early greatly increases the chance of survival and minimises cardiac damage.
When a patient comes to the office for care and then leaves and goes home the type of care the patient has received is called?
outpatient
Is a patient happy when his disease goes into remission?
Yes
Is fibrillation dangerous?
Atrial fibrillation (A-fib) is a very dangerous condition. In A-fib, the heart is trying to pump too fast, but is uncoordinated. This means that blood is not circulated around the body well. It also causes blood to swirl around inside the heart and can lead to forming blood clots. If one of these blood clots goes to the lungs it can cause a pulmonary embolis, or if it goes to the brain it can cause a stroke, both of which could be deadly.
What may happen if you administer medication and you are not trained?
If first aid is not given then the patient bare the pain and can cause death.
What is a good Example of when CPR is needed?
Resuscitation is only needed when a heart goes into ventricular fibrillation (Vfib). Many people think it's also needed when a heart goes into asystole (the well-known flat line), but it will not work then.
What is the difference between heart rate and ventricular rate?
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
