Electromagnetic Interference between Subcutaneous ICD and HeartMate II LVAD

Clinical differences between continuous flow ventricular assist devices: a comparison between HeartMate II and HeartWare HVAD.

BACKGROUND The HeartWare ventricular assist device (HVAD) is a new generation centrifugal flow VAD recently introduced in Canada. The objective of this study was to compare the HVAD device to the HeartMate II (HMII) axial flow device. Very few studies have compared clinical outcomes between newer generation VADs. METHODS All perioperative and follow-up data on LVAD recipients were collected p...

Early Experience with the Subcutaneous ICD

The Subcutaneous Internal Cardiac Defibrillator (S-ICD) represents a major advance in the care of patients who have an indication for an internal cardiac defibrillator without pacing indications. Its main advantage is that it can deliver a shock to cardiovert ventricular arrhythmias utilising a tunnelled subcutaneous lead, negating the risks associated with conventional transvenous systems. Ini...

Subcutaneous ICD lead position affects defibrillation threshold

Introduction Subcutaneous implantable cardioverter-defibrillators (S-ICD) provide an alternative to traditional transvenous implantable cardioverter-defibrillators (TV-ICD) and avoid complications associated with intravascular access and leads. They are highly effective in detecting and treating ventricular arrhythmias, with comparable inappropriate shock rates. Use of S-ICD is anticipated to i...

Electromagnetic Interference from Swimming Pool Generator Current Causing Inappropriate ICD Discharges

Electromagnetic interference (EMI) includes any electromagnetic field signal that can be detected by device circuitry, with potentially serious consequences: incorrect sensing, pacing, device mode switching, and defibrillation. This is a unique case of extracardiac EMI by alternating current leakage from a submerged motor used to recycle chlorinated water, resulting in false rhythm detection an...
