Signal Processing
Changing this increases all noise and signal equally
What is the Gain?
Catheter you would pace from to see if retrograde conduction occurs
What is RV catheter?
The term for pacing at a given cycle length that progressively gets faster the longer the test is run
What is decremental/ramp pacing?
The chamber you would pace from and what you would lose to see AVNERP
What is the atria and lose conduction?
The catheter(s) that you would see an H signal on
What is the his catheter?
Filter that eliminates frequencies above a specific frequency
What is a low-pass filter?
Catheter used to determine right to left atrial activation
What is the CS catheter?
Pacing in order to control the heart rate
What is overdrive pacing?
The chamber you would pace from and what you would lose to see VERP
What is the ventricle and capture?
The type of signal that provides directionality information.
What are unipolar signals?
Filter that eliminates frequencies below a specific frequency
What is a high-pass filter?
Signals you would see on a CS catheter
What are A's and far field V's?
Pacing maneuver to test for refractory periods among other things.
What is extra-stimulus pacing?
The chamber you would pace from and what you would lose to see retrograde AVNERP
What is the ventricle and conduction?
Signal type that has the greatest signal to noise ratio
What are bipolar signals?
Filter that is a combination of a high pass and low pass filter
What is a bandpass filter?
CS activation that goes from proximal to distal
What is concentric activation?
Pacing maneuver to test when loss of 1:1 AV conduction occurs
What is decremental/ramp pacing?
The chamber you would pace from and what you would lose to see AERP
What is the atria and lose capture?
Signal type that is best used for finding the focus of a tachycardia
What are unipolar signals?
Filter used to eliminate a single frequency
Signals you should see on a his catheter
What are A, H, and V?
Pacing to induce a tachycardia
What is burst pacing?
What is greater than 35 ms?
Two things you would need to see to show AVNRT can occur
What are echo beats and an AH jump?
