Heart Rhythm New Zealand consensus statement on the practical management of cardiac implanted electronic devices in the peri-operative environment.

Electrosurgery is commonly used during a range of operations in order to maintain effective haemostasis. This can cause electromagnetic interference (EMI) with cardiac implanted electronic devices (CIEDs), which prevents normal device function. CIEDs include pacemakers (PPM), implantable cardiac defibrillators (ICD), cardiac resynchronisation therapy devices-both pacemakers and defibrillators (CRT-P/CRT-D)-and implantable loop recorders (ILRs). Damage to the generator, inhibition of pacing, activation of asynchronous pacing and ventricular fibrillation can all be induced by electrocautery. An active management plan for CIEDs during electrosurgery is critical to minimise these adverse effects of EMI. Purpose: To facilitate the safe and effective peri-operative management of CIED patients during electrosurgery.
