Key result
Cutaneous ILRs provide clinically useful information for evaluating unexplained collapse in two dogs.
Why the study?
Diagnostic surface ECG and 24 hr Holter monitoring can be inconclusive for frequent collapsing episodes, and implantable loop recorders have limitations in veterinary use due to risks and costs.
Does cutaneous placement of implantable loop recorders provide clinically useful information in dogs with unexplained episodes of collapse?

Does cutaneous placement of implantable loop recorders provide clinically useful information in dogs with unexplained episodes of collapse?
Cutaneously placed implantable loop recorders offer an effective diagnostic alternative for dogs with unexplained collapse when owners decline surgical implantation.
May aid diagnosis of recurrent collapse in veterinary patients when surface monitoring fails; hypothesis-generating for ILR adoption.
Determining the cause of episodes of collapse can be difficult. Even in patients with frequent collapsing episodes due to cardiac causes, diagnostic surface electrocardiogram and 24 hr ambulatory electrocardiographic (Holter) monitoring are sometimes inconclusive. Event monitors with multiple leads can be challenging to use in veterinary medicine over long periods of time due to lead dislodgment. Implantable leadless loop recorders (ILRs) are useful, but owners are sometimes unwilling to have an ILR implanted due to the associated risks and/or costs. In this case report, the authors describe the use of cutaneously placed ILRs in two dogs with unexplained episodes of collapse/exercise intolerance. Data recorded provided clinically useful information. Cutaneously placed ILRs can be used effectively in veterinary medicine to evaluate patients with unexplained episodes of collapse.

Sanders et al. (2012) conducted a case report in Unexplained episodes of collapse/exercise intolerance (n=2). Cutaneously placed implantable loop recorders (ILRs) was evaluated on Clinical utility of recorded data. Cutaneously placed implantable loop recorders provided clinically useful information for evaluating two dogs with unexplained episodes of collapse.
