Brief Summary:
The aim of the study is to collect data from surface ECGs by using Holter ECG recordings from patients with different forms of diagnosed arrhythmias and/or specific ECG characteristics from heart diseases to support the development of new sensing and detection algorithms for implants.

12-channel Holter ECG recording for non-EPS patients
Patients scheduled for a follow-up for their heart disease will undergo a 12-channel Holter ECG recording while participating in a Body Motion test followed by a 24 h observation period
Diagnostic Test: 12-channel Holter ECG recording
12-channel Holter ECG recording for patients undergoing a routine follow-up
