Title: Anti-Arrhythmic Effects of Exercise After an Implantable Cardioverter Defibrillator (ICD)
Brief Summary: An implantable cardioverter-defibrillator (ICD) is a small device that is surgically implanted in the chest or abdomen and uses electrical pulses or shocks to help control life-threatening, irregular heartbeats. Increasing aerobic exercise may provide health benefits to people with ICDs. This study will examine the effects of an exercise program on heart and lung function in people who have an ICD.


Options:
A: Inclusion Criteria:

1. Men and women admitted for an IHD event (acute coronary syndrome or revascularization procedure) who are at low or moderate risk.91
2. Regular Internet access (home, work or other environment).
3. Over 18 years of age.
4. Permission of the attending physician.
5. Able to read, write and understand English without difficulty.
6. No physical limitations to regular activity.

Exclusion Criteria:

1. Previous experience with a cardiac rehabilitation program.
2. Patients with depression, uncontrolled diabetes and other significant co-morbidities that may interfere with effective IHD management.
3. Those patients, who in the mind of the attending physician, are unsuitable for participation.
4. Those unable to provide informed consent.
5. Pregnant women.
6. High-risk patients for safety considerations (future studies will include high-risk patients).

* Indication for exercise training according to the Dutch clinical algorithm for assessment of patient needs in cardiac rehabilitation.
* Internet access and PC at home (i.e. more than 90 percent of the Dutch household)

Exclusion criteria:

* High risk according to the Dutch CR practice guideline.
* Systolic heart failure (left ventricular ejection fraction of more than 40 percent.
* New York Heart Association class III-IV (i.e. breathlessness during light exercise or at rest).
* Severe arrhythmia.
* Hemodynamically significant valvular disease.
* Implantable cardioverter-defibrillator (ICD) implantation
* Heart transplantation.
* Chronic angina or silent ischemia.
* Comorbidity impairing exercise capacity (e.g. COPD, diabetes mellitus, peripheral vascular disease and orthopedic or neurological conditions).
* Severe psychological or cognitive impairments.
