Abstract
In this work, a novel ambulatory ECG monitoring device developed in-house called HOLTIN is analyzed when operating in complex indoor scenarios. The HOLTIN system is described, from the technological platform level to its functional model. In addition, by using in-house 3D ray launching simulation code, the wireless channel behavior, which enables ubiquitous operation, is performed. The effect of human body presence is taken into account by a novel simplified model embedded within the 3D Ray Launching code. Simulation as well as measurement results are presented, showing good agreement. These results may aid in the adequate deployment of this novel device to automate conventional medical processes, increasing the coverage radius and optimizing energy consumption.

Summary
Ambulatory Electrocardiogram (AECG) monitoring services are among the most relevant. Ubiquitous Health (U-Health) applications due to the high prevalence of cardiovascular disease [1,2]. AECG services that allow continuous and long-term patient monitoring are required to improve diagnosis and treatment of cardivascular diseases. In this sense, cardiologists are very interested in new U-Health services aimed at monitoring of patients that suffer from paroxysmal arrhythmias and sporadic syncopes. AECG monitoring services used by cardiologists are based on conventional Holter devices and implantable loop recorder systems [4,5,6] These systems fulfill the patient’s cardiac activity monitoring and allow detecting several types of arrhythmias. These systems present several limitations such as the duration of the monitoring session due to a limited storage capacity and reduced ergonomics.
