What are the differences between synchronous and asynchronous cardioversion?
Synchronus cardioversion is when shock is delivered on QRS portion of the heart cycle (time when ventricle depolarises). It is used when pulse is present in a patient usually greater than 150/min and sign and symptoms usually of tachycardia. Like in Atrial Fibrillation. But in case of asynchronus cardioversion shock can be given at any time of heart cycle. Pulse is absent like in Ventricular Fibrillation.
How is DDAVP administered?
It can be administered as a nasal spray, intravenously, or as a tablet.
The joules for biphasic defibrillator cardioversion?
The starting joules should be 100-120. This will generally result in 90% first shock success in patients with persistent A-Fib.
What is administered in preparation for a nuclear scan?
radiopharmaceutical
How does the hepatic portal circuit affect the efficacy of oral medications?
The hepatic portal circuit is responsible for transporting blood from gastrointestinal tract to the liver. Certain medication which are administered orally cannot be passed via this system and therefore should be administered via alternative methods such as injections.
The use of electrical shock to restore the heart's normal rhythm is known as?
Defibrillation also known as cardioversion.
What are the first steps of an elective cardioversion?
After arriving at the hospital, an intravenous (IV) catheter will be placed in the arm and oxygen will be given through a face mask. A short-acting general anesthetic will be administered through the vein.
What disorders is cardioversion used to treat?
Most often, cardioversion is used to treat atrial fibrillation or atrial flutter. Life-saving cardioversion can be used to treat ventricular tachycardia and ventricular fibrillation.
What is synchronized cardioversion?
From the related link, Synchronized Cardioversion is: --A controlled form of defibrillation for patients who still have organized cardiac activity with a pulse.
What does a cardioversion accomplish?
Cardioversion is used to stop this abnormal beating so that the heart can begin normal rhythm and pump more efficiently.
Why is it often necessary to repeat cardioversion?
in about 50% of cases, the heart prefers its abnormal rhythm and reverts to it within one year, despite cardioversion.
What conditions require immediate cardioversion?
Ventricular tachycardia lasting more than 30 seconds and ventricular fibrillation require immediate cardioversion.
What is cardioversion also called?
direct current.
What is the CPT code for cardioversion?
CPT 92960
What takes place in the process of cardioversion?
During the process of cardioversion, an electrical shock is delivered to the heart in an attempt to change an irregular heart beat rhythm into a normal one.
Can a cardioversion procedure be dangerous?
Cardioversion is carried out frequently in Hospitals and is quite safe in good trained and expert hands. Like any procedure it does carry some risks
What potential exists for a cardioversion to fail?
A cardioversion can fail due to underlying heart conditions like atrial fibrillation or flutter. Other reasons include improper electrode placement, incorrect energy settings, or failed synchronization with the heart's electrical activity. In some cases, medication resistance or conduction issues can also lead to a failed cardioversion.
