Accurate detection of f waves during atrial flutter is difficult. However, f waves contain information on the pathology and are useful for non-invasive diagnosis. The setup and difficulties of f wave detection lends itself to the use of statistical signal detection techniques. Real-life constraints can be modeled in the signal observation using...

The use of the ECG as a diagnostic tool for analyzing supraventricular arrhythmia avoids invasive procedures prior to clinical intervention. Analysis of atrial activity may indicate properties of the underlying arrhythmia. In atrial flutter, there is a high synchroneity between atrial and ventricular activity. Statistical and classical...

Atrial flutter circuit localization is usually determined during a catheter ablation procedure. Knowledge of this information beforehand could aid clinicians assess and plan the operation in advance to improve efficacy. Variability as a marker to discriminate localization non-invasively was suggested in the literature, and evaluated by one...

Propagation of electrical atrial activity (AA) during atrial fibrillation (AF) is a process characterized by different short-and long-term recurrence behaviours. Two anti-thetical (not mutually exclusive) hypotheses are proposed to noninvasively describe this nonstationary behaviour. The first hypothesis (H1) assumes a process with stationary...
