Cardiac arrhythmia

Abstract

Mechanical stimulation from the catheter can result in many types of atrial and ventricular arrhythmias. Possible reasons for delayed arrhythmias include catheter malposition at the time of placement and postplacement migration. If the cause of arrhythmia is the embolized fragment of the catheter, a fatal cardiac complication such as ventricular fibrillation and sudden cardiac death may occur. The correct catheter tip position is mandatory to avoid this complication. Optimal tip position is usually at the junction of the superior vena cava and right atrium.
