The 24-hour ambulatory electrocardiography, commonly known as Holter monitoring, is a diagnostic method to correlate clinical symptoms with cardiac arrhythmias. The Holter monitor records electrical signals from the heart using electrodes attached to the chest, which are connected via cables to a digital recorder. In addition to the device to record the cardiac electrical signals, the Holter system also has a software for review and analysis of the record. The software of the Holter system has an integrated automatic analysis process to detect different sorts of heart beats, rhythms, etc, which are then validated by a technician and a physician. The success of the automatic analysis depends of the quality of the captured electrical signals, which are dependent on the appropriate attachment of the electrodes/cables to the patient body. Therefore, inappropriately attached electrodes/cables can result in electromagnetic disturbance that can interfere with the ECG signal, resulting in a very noisy record that is hard to be analysed. Newer Holter systems that eliminate the cables and attach the recorder directly to the electrodes positioned in the patient´s chest might reduce the electromagnetic disturbance in the ECG signal capture and, therefore, improve the quality of the exam. This study will compare the findings of a Holter exam using a newer system, the QuoreOne system from QuoreTech, with a more traditional system, the Cardiolight system from Cardios.
