Triggers and Risk Factors for Recurrence of Atrial Arrhythmias With the Use of Long-term Monitoring

Patients will use a 1-lead Holter ECG (Bittium Faros) for heart rhythm and physical activity analysis, a wearable wrist-worn device with photoplethysmography and 6-lead ECG for heart rhythm analysis, a sleep tracking mat (Withings sleep analyser) for sleep analysis, a smartphone with triggers application for entering the subjective triggers (stress, coffee, alcohol intake and others), a 48-hour ambulatory blood pressure monitor for 2 days and a regular blood pressure monitor for up to 5 days. Patients will be monitored for up to 7 days with the described system of devices. In addition, patients will receive investigations of heart echocardiography, laboratory tests and surveys to evaluate the system and the use of acquired information.
