What is Cardioversion?
|
The use of the defibrillator to terminate arrhythmias other than V-Fib
|
|
|
How does cardioversion differ from defibrillation?
|
The current is synchronized with the ECG so that it will not be delivered during the vulnerable period (on top of the T wave).
|
|
|
How does the R on T phenomenon work?
|
When the defibrillator fires at the top of the T wave. This usually results in the rhythm changing to V-Fib.
|
|
|
What is emergency cardioversion used for?
|
Usually reserved for rapid ventricular and supraventricular rhythms associated with severely compromised cardiac output.
|
|
|
What is transcutaneous cardiac pacing?
|
Artificial pacemakers whereby a small electric charge is passed through a patients skin and across the heart between one externally pad and another.
|
|
|
How is the TCP set?
|
The pacer is set for a specific rate and the energy is increased until the heart just begins to respond to the stimulus.
|
|
|
What is this called?
|
The phenomenon is called capture and is associated with the depolarization of the ventricles which appears as a wide QRS complex with a corresponding pulse.
|
|
|
What are Pneumatic CPR devices?
|
Started out with a piston that compressed chest. Modified to include a suction cup to aid with recoil and now have moved to vest type garments which compress in more specific places.
