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 does a defibrilator do?

It produces an electrical impulse used to restart the hearts' rhythm after a cardiac arrest.


What are the benefits of having a defibrillator implant?

An implanted defibrillator has both risks and benefits to the patient. The implant is used for those who are at risk for cardiac arrest, and in the event of a cardiac arrest, the defibrillator implant could save the patients life by maintaining a steady cardiac rhythm.


In cardiac arrest the AED defibrlillates over time?

If it is a shockable rhythm, the AED will analyze and defibrillate as needed. Continue CPR when not analyzing and/or shocking.


Who should not receive defibrillation?

Defibrillation should not be performed on a patient who has a pulse or is alert, as this could cause a lethal heart rhythm disturbance or cardiac arrest.


What happens in hospital when someone arrests?

A cardiac arrest team will be called in, and the staff will start CPR immediately, they will use a BVM and Defib (if necessary) to attempt to resus the patient the cardiac arrest team will then move in and perform ALS on the patient. Usually the patient will go into respiratory arrest and then cardiac arrest, their heart rhythm will normally go from normal synas rhythm into VF (Ventiricualr Fibrillation) where a shock will be nececerry to stop the heart, and shock it back into normal rhythem. If the patient receives early CPR and early Defib they have a fairly good chance of surviving if they go into VF. Hope this helps.


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 many volts in a defibrillator?

A defibrillator typically delivers between 200 and 1000 volts of electrical charge to the heart in order to restore a normal rhythm during sudden cardiac arrest.


What is a sinus arrhythmia?

This is an irregular cardiac rhythm due to a variation in the sinus rhythm -- the heartbeat usually increases during inhalation and decreases during exhalation. This condition is common in children and young adults.


What converts cardiac arrhythmia into normal sinus rhythm?

defibrillators


What is a cardiopulmonary arrest?

Cardiopulmonary arrest, also known as cardiac arrest, is a sudden loss of heart function that results in the stopping of blood circulation. This can lead to the stopping of breathing and ultimately result in unconsciousness and death if not treated promptly with cardiopulmonary resuscitation (CPR) and defibrillation.


A twitching of the cardiac muscle that is not in a sustained rhythm is called a?

murmer or fibrillation
