However, it represents an artifact called “pseudo double T wave”. The cause is unknown but most likely due to abnormalities at the interface between surface electrodes and skin tissue. The diagnosis of ECG artifacts requires meticulous examination of the tracings coupled with a thorough knowledge...
This patient went on to have an electophysiology study, which confirmed the diagnosis, followed by slow pathway ablation. This led to resolution of his symptoms and normalization of hisECG. This is an uncommon presentation of dual AV nodal physiology "double-fire" with AV fast and slow pathway...
The ECG showed synus rhythm, left–axis deviation, Q wave and ST–elevation from V2 to V5 and in DIII and ST–elevation in DII and aVF (FIGURE 1). Transthoracic echocardiography revealed concentric hypertrophy, mildly reduced LV ejection fraction (EF 45%) with akinesia of intreventricular ...

The maximum first derivative plus the maximum value of the double search algorithm is applied on electrocardiogram(ECG) of MIH-BIT Arrhythmia Database to extract R wave. Through the study of algorithm's characteristics and R-wave detection method, data segmentation method is modified to improve ...
The sleep stage was defined following the American Academy of Sleep Medicine guidelines by two proficient neurophysiologists, who were masked to the patient’s clinical assessments. Patients with no sleep pattern were defined if only wake or slow-wave sleep (SWS) were identified during the recording...
There were no significant differences between the treatment populations in ECG rhythms at 5 s or 10 s, at 1 min or 5 min or 1 h after the shock, providing successful cardioversion had occurred. After 1 h 68/70 (97%) of the biphasic and 77/85 (91%) of the monophasic patients were ...
A six-lead ECG strip from a 1.2-year-old male Golden Retriever demonstrating atrial fibrillation with widened (80 ms) and splintered QRS complexes, compatible with a RBBB pattern and mild right axis deviation of the ventricular depolarization mean electrical axis (1 cm/mV, 50 mm/s). Note tha...
(nTaFl;)Foifg.5 4m).TT.he transverse muon-polarization was used in zero applied field (ZF) and in Computational methods. To understand the magnetic interactions in BMTO, DFT calculations have been performed using the plane-wave-pseudopotential approach as implemented in Quantum E S...
