What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
Is atrial fibrillation worse that ventricular fibrillation?
No, ventricular fibrillation is worse than atrial fibrillation. This is because the ventricle is the chamber responsible for the main force pumping the blood out of the heart. If this contraction is not coordinated (like when fibrillation occurs), then the heart will not be able to function and consciousness will be lost within a few seconds. Ventricular fibrillation may result from electric shock, major myocardial infarct or some anaesthetic drugs. Resuscitation is usually possible by applying an electric shock (defibrillation) - which causes all cells to enter the refractory period and gives the sinoatrial node a chance to resume its normal pacemaker activity.
How do you fix cardiac arrhythmia?
If you are referring to atrial fibrillation, there are several medications used to prevent recurrence, or to control the heart rate. If you are referring to ventricular fibrillation, correction and prevention frequently requires the insertion of a defibrillator and possibly a pacemaker. If you are having frequent ventricular tachycardia or fibrillation, your heart is very damaged and a defibrillator/pacemaker may be the only way to prevent sudden death.
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 sinus rhythm with occasional premature ventricular complexes?
Sinus rhythm, the natural beating of the heart begins in the sinoatrial (or sinus) node and is located in the wall of the right atrium. Occasional premature ventricular complexes are abnormal heartbeats that disrupt the regular rhythm of the heart. The irregular heartbeats begin in one of the ventricles in the lower part of the heart.
What is the most frequent initial rhythm witnessed in sudden cardiac arrest?
The most common abnormal heart rhythm preceding cardiac arrest is ventricular fibrillation. In this dysrhythmia, the ventricular walls contract randomly and rapidly, and do not effectively pump blood.
What is the medical term meaning abnormal heart rhythm that causes the ventricles to quiver?
Atrial fibrillation is the medical term meaning the irregular, uncoordinated, ineffective twitching contraction of the walls of the atria. A related condition is ventricular fibrillation, which occurs in the lower chambers of the heart.
For which cardiac rhythm and other problems is CPR required?
The two most common heart rhythms that require CPR is ventricular tachycardia and ventricular fibrillation. Ventricular tachycardia is an extremely rapid cardiac rhythm and ventricular fibrillation is an abnormal cardiac rhythm. For an adult, if the person is unconscious and not breathing, CPR is required. There are numerous reasons an adult would be unconscious and not breathing; all require CPR.
How can ventricular fibrillation be prevented?
A healthy lifestyle to reduce the risk of heart diseases which lead to ventricular fibrillation is the best prevention.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
What is the reason for SCD?
Sudden cardiac death is usually caused by ventricular fibrillation (the lower chamber of the heart quivers instead of pumping in an organized rhythm).
Identification of Ventricular fibrillation?
Ventricular fibrillation is the most serious cardiac arrhythmia and it means simultaneous haphazard electrical activity of the Heart and it occurs in death. If the patient has collapsed with no pulse and the monitor shows a flat wave, then its Ventricular fibrillation.
What heart conditions is propafenone used for?
heart arrhythmias usually of the more dangerous kind. Like ventricular tachycardia and ventricular fibrillation.
Is ventricular tachycardia a type of abnormal heart rhythm?
Ventricular tachycardia is an abnormal heart rhythm in which the heart beats rapidly due to electrical stimulation coming from the ventricle.
What is the only effective treatment for ventricular fibrillation?
The only effective treatment for ventricular fibrillation is defibrillation. Defibrillation is the delivery of a controlled electrical shock to the heart to stop the erratic electrical activity of fibrillation and allow the sinoatrial node to take over pacing the heart normally.
What is in abnormal rushing or blowing sound That results from a damaged heart valve?
Ventricular fibrillation
Fibrillation instead of pumping strongly the heart muscle quivers ineffectively?
Ventricular
