Bradyarrhythmias as AV-block or Sinusarrest, often require implantation of a pacemaker to restore a normal heart rate. Untreated, these conditions lead to exercise intolerance, syncope, heart failure or even sudden cardiac death. More commonly, these problems are found in older patients, but are sometimes also seen in younger patients.
Implantation of a pacemaker provides patients usually with a normal quality of life. Clinical signs like exercise intolerance and syncope will disappear.
Many different pacemaker systems exist. More commonly, single chamber pacemaker systems, with only one pacemaker lead in the right ventricle, are fitted in dogs.
This is probably sufficient for many patients and takes care of the risk of sudden cardiac death. Nevertheless, implantation of the more complex dual chamber pacemaker units which we also offer at SCVS can be beneficial in certain patients and could result in a superior outcome.
Implantation of pacemakers is performed via cutdown to the jugular vein. The vein is used to feed the electrode(s) into the heart. The pacemaker itself is then positioned subcutaneously in the neck area. Implantation is therefore very minimally invasive, and patients can usually be discharged 1-2 days following surgery.
Optimal programming of the pacemaker is essential for best results. We are running pacemaker clinics, a cooperation with human electrophysiologists, to ensure pacemakers for all our patients are set in the best possible way.
- SCVS offers the option of single and dual chamber pacemakers to achieve best results for all patients
- Predominant use of active electrodes to minimise the risk of lead dislodgement
- Pacemaker clinics with electrophysiologist to ensure best possible pacemaker programming
