What is Electrophysiology?
Electrophysiology: The science of the study of flow of electricity controlling the movement of the heart
The heart is a pump responsible for the blood flow inside the artery and veins
Any upset or malfunction of electricity Organization certainly cause trouble and energizes the contraction of the heart muscle and therefore disturbed blood flow to organs of the body, which may cause death in cases of continuous turmoil and rapid

Devices used in diagnosis
• ECG
• Stress test ECG
• Holter
• Echo Ultrasound
• EP study
• Cardiac stimulator

Global Properties of an EP Catheter
• Sizes
Shaft and Tip ( French size ).
• Spacing
Between Electrodes ( mm spacing ).
• Curves (Fixed, Deflectable)
Different Access and anatomical selection.
• Number of electrodes
Different Mapping Selections
Tip electrode
• Tip length per catheter type• Ablation catheters
• 3,5mm/4mm/8mm
• Diagnostic catheters• 1,3mm or plastic dome
1,3mm - diagnostic
3,5/4/8mm - ablation
