WebJun 2, 2024 · Disclosed are various examples and embodiments of systems, devices, components and methods configured to extract atrial signals from electrical signals acquired from a patient suffering from atrial fibrillation. The electrical signals acquired from the patient may be intra-cardiac signals or body surface electrode signals, or both. WebThe T wave represents the uncanceled potential differences of ventricular repolarization. 33 The ventricular recovery process proceeds in the general direction of ventricular excitation. Hence one would expect the polarity of the T wave to be opposite that of the QRS complex with a zero net area of the ventricular complex (i.e., QRS and T).
