Contents
* ICD History
* Basic functions of defib
* Sensing, detection and therapies
* ICD indications-who gets one or not
* Implant procedure-how do we test the device
.
Basic Functions of ICD
* Automatically detect and treat Ventricular Tachycardia (VT)
* Antitachycardia pacing (ATP)
* Cardioversion
* Automatically detect and treat Ventricular Fibrillation (VF)
* Defibrillation
* Brady pacing
* VVI, VVIR, DDDR
How it works
* Sensing
* Detection
* Therapy
Three Zone Detection
* VT
* FVT
* VF
Therapies
* ATP
* Burst
* Ramp
* Ramp+
* Cardioversion
* Defibrillation
ICD Indications, who gets one or not
Implant Procedure
* Insertion ofdefib leads
* Test pacing parameters through analyzer of P / R wave, lead impedances, and pacing threshold
* Connect defib leads with defib box
* Test pacing impedance, threshold through the box
* Induce VF, implant success criterion: two consecutive times or 3 out of 4 successful defibrillation, 10 J safety margin.
* Turn of detection, close the wound
* Final programming
