OBJECTIVE: We examined patients with implantable cardioverter defibrillators (ICD) in order to demonstrate their safe participation in a standard rehabilitation program. DESIGN: Prospective cohort study of a consecutive series of patients after ICD implantation. Setting Inpatient rehabilitation center. PATIENTS AND METHODS: A total of 118 patients (73.7% male, mean age 60+/-11 years) took part for 23 +/- 4 days in a standard inpatient rehabilitation program including physical activity, psychological care, heart function seminars, and resuscitation exercises with family members. The following noninvasive tests were performed: symptomlimited exercise testing, two-dimensional echocardiography, Holter monitoring, telemetric ICD interrogation, optional fluoroscopy or X-ray examination of the thorax, and (in some patients) defibrillation threshold testing. RESULTS: Out of 118 patients 101 patients (85.6%) participated in regular ergometer training during which the initial workload of 23 +/- 11 Watts could be increased to 45 +/- 18 Watts. An individual conditioning program was assigned to 15% (n = 17) patients, thereby enabling the inclusion of all patients in the rehabilitation process. Under these conditions 12 patients (10%) experienced ICD malfunctions requiring therapy. As a consequence of all cardiac function tests, ICD reprogramming was necessary in 26 patients (22.1%). CONCLUSION: Following ICD implantation, patients may participate in a standard rehabilitation program without serious complications and with a significant increase in physical capacity. However, ICD malfunction occurs in approximately 10% of patients. Additional tests performed by skilled medical staff and appropriate technical equipment allows the ICD program to be optimized.
