Cardiologists' perspective on termination of pacemaker therapy-an anonymous survey among cardiologists in Germany.

Background: The patient's right to refuse pacemaker therapy is mentioned in the relevant European consensus statement but additional information is only available on deactivation of implantable cardioverter deactivator and not on other cardiac implantable electronic devices such as pacemakers. Therefore, we were interested in opinions, concerns and attitudes of cardiologists, who are the primary contact persons for such requests, since the number of patients asking for withdrawal of pacemaker therapy is likely to increase leaving cardiologists and healthcare professionals with a difficult medical but also ethical problem.

Methods: An anonymous questionnaire was sent to all German cardiology departments (N = 288).

Results: 48% of cardiology departments responded by sending back 247 completed questionnaires. Most participating cardiologists were experienced when considering the duration of their professional activity. Almost all of the respondents regularly perform check-ups of pacemakers. The majority of cardiologists answering our questionnaire were prepared to deactivate a pacemaker upon patients' request, and have done so. In pacemaker dependency, however, the willingness to withdraw decreases, even if death is imminent, for fear of causing distressing symptoms, sense of being responsible for patients possible immediate death, or fear of legal consequences.

Conclusions: The survey could clearly show that uncertainties remain among cardiologists dealing with a patient's wish for withdrawal, especially in cases of pacemaker dependency. We suggest that official statements of cardiologic societies in Europe are issued to clarify ethical, legal and practical aspects of pacemaker withdrawal.
