A total of 500 subjects from 15 cardiology centers of the Veneto region will be included.', 'detailedDescription': 'The primary objectives of this study are as follows:\n\n* Determine if the changes of temperature, pressure and humidity, are associated with an increase of atrial and ventricular arrhythmias.\n* Determine if the changes of air pollution (gas and particulate), are associated with an increase of atrial and ventricular arrhythmias.\n\nThe secondary objectives of the study are:\n\n* Determine if the changes of air pollution (gas and particulate), are associated with significant changes in mean heart rate, rate variability rate and the percentage of paced beats.\n* Determine whether changes in temperature, pressure or humidity, are associated with significant changes in mean heart rate, heart rate variability and the percentage of paced beats.\n* Determine if the changes of temperature, pressure and humidity, are associated with an increase in mortality or hospitalization for myocardial infarction or congestive heart failure.\n* Determine if the changes of air pollution (gas and particulate), are associated with an increase in mortality or hospitalization for myocardial infarction or congestive heart failure.\n\nStudy Design This is a prospective, observational study, which compares the occurrence of atrial and ventricular arrhythmias and changes in physiological parameters, with climatic variables and air pollution.\n\nThe study will include 500 subjects and will consist of two periods:\n\nScreening: we will collect baseline characteristics of subjects in the clinical examination. The period recruitment will run for 12 months.\n\nFollow-up: After written informed consent will be signed, subjects who meet the criteria for inclusion will be enrolled in the study and followed up for a minimum period of 12 months. The data obtained from the remote monitoring will be evaluated for the daily values provided for the parameters considered in the study.\n\nPeriodical visits in pacemaker clinic will be scheduled at the discretion of the referring cardiologist of the center. The arrhythmic events that will occur in this period, detected by means of remote monitoring or through other clinical evaluations will be recorded. Atrial arrythmias: atrial fibrillation or atrial flutter, supraventricular tachycardia.\n\nVentricular arrhythmias: ventricular tachycardia, ventricular fibrillation, ventricular extrasystoles.\n\nPhysiological variables: average heart rate (24 hours and at rest), heart rate variability, the percentage of paced beats.\n\nIn addition, any changes in drug therapies and all clinically relevant events, will be recorded.\n\nDuring the same period data from monitoring stations of ARPAV (Regional Agency for Environmental Prevention and Protection of Veneto Region) will be collected.\n\nClimatic variables: temperature, humidity, atmospheric pressure. Parameters of air pollution: PM10, PM2.5, O3, CO, SO2, NO2. For each patient, the data from the monitoring station ARPAV of the urban area of residence of the subject will be considered. The mean exposure level used in the analytical studies on the health effects is calculated on the average number of units active in the area. This number is usually of 2-3 units in large centers, while it is generally only 1 in small towns. The residents in centers without monitoring will be excluded from the study.
