This cardiac structure initiates atrial depolarization and acts as the natural pacemaker
What is the sinus node?
35-55 ms is a normal interval between these two signals
What is H-V?
The mapping system with the best looking mappers
What is Abbott/ESI/Jack?
This cardiac structure receives the electrical impulse from the atria then sends the signal to the ventricles via the HIS-Purkinje system
What is the AV node?
50-120 ms is a normal interval between these two signals.
What is A-H?
This structure is located in the left atrium and is known for harboring clots in AF patients due to blood stasis.
What is the Left Atrial Appendage?
This reciprocating tachycardia passes through the fibrous tissue located between the tricuspid valve and the IVC, an area known as the isthmus.
What is typical flutter?
This rhythm is characterized by intermittent disruption at the level of the AV with a lengthening of the PRI.
What is Wenckebach?
This type of mapping involves the use of patches or magnets that give impedance feedback and assist the operator in locating the catheter in real-time space to help with identifying cardiac anatomy and ablation lesion sets.
What is 3D mapping?
This phenomenon is used to describe the inability of electrically paced stimuli to exit the pulmonary veins.
What is exit block?
This electrically inert area of the heart separates the atria from the ventricles and normally does not allow electricity to pass through
What is the AV groove?
This Supraventricular tachycardia originates in the atria, may be either focal or mutifocal, and may present with varying P wave morphology or varying PR intervals.
What is atrial tachycardia?
This phenomenon describes the movement of electrical activity from a fast pathway to the slow pathway in the HIS. It's demonstrated by an increase of 50 or more ms of the AH interval on the HIS catheter from the last two paced atrial beats.
What is an AH jump?
This type of map, used to determine the viability of LV tissue, will help the physician assess which tissue is scar, and which is healthy.
What is a voltage map or a scar map?
When ablating AF, passing over these areas while ablating in the left atrium may produce a vagal response, requiring immediate pacing.
What are the ganglionic plexii?
When viewed on intracardiac signals, this electrical activity represents a slow moving electrical channel through scar during a VT ablation.
What are mid-diastolic potentials?
Certain catheters deliver trains of high-voltage, ultra-rapid electrical pulses that form irreversible pores in cell membranes which is an example of what phenomena?
What is electroporation?
This complication can occur when a rise in esophageal temperatures manifests during ablation without corrective action. It can lead to sepsis and has a very high mortality rate.
What is atrioesophageal fistula?
