Case Study


High Ventricular Rate Episode

Fifty-five year old female with suspected atrial fibrillation was implanted with an Abbott Confirm RX implantable loop recorder on December 30th. On New Year’s Eve at approximately 1am, a high ventricular rate alert transmission was received. Technician interpretation showed intermittent atrial fibrillation and a sustained VT/VF episode with rates above 280 bpm. Both patient and physician were contacted and the patient was implanted with an ICD the following morning. Since implant, the patient has had a number of successful shocks delivered and is doing well. This episode demonstrates the need for 24/7 monitoring of all implantable loop recorders.
