Implantable loop recorders have emerged as a technology which requires a surgical procedure and can potentially record continuous rhythm for its battery life which usually lasts approximately three years. The procedure can also lead to explantation secondary to erosion or migration. Some cardiologists and electrophysiologists use the ILR post ablation for AF surveillance. This affords long term surveillance, however the device is costly and there is a risk of infection as well. Novel technology termed LTCM has the capability to record and store continuous ECG for up to 14 days.
