Background: An abnormal Q wave is usually defined as an initial depression of the QRS complex having a duration of ≥40 ms and amplitude exceeding 25% of the following R wave in any contiguous leads on the 12-lead electrocardiogram (ECG). However, much smaller Q waves are sometimes ...
The heart A patient's ECG tracing shows a consistent pattern on two P waves followed by a normal QRS complex and T wave. a. What is the cause of this abnormal wave pattern? b. What signs might the patient exhibit? Fill in the blan...
Wavelet Based QRS Complex Detection of ECG Signal The Electrocardiogram (ECG) is a sensitive diagnostic tool that is used to detect various cardiovascular diseases by measuring and recording the electrical activity of the heart in exquisite detail. A wide range of heart condition is det... S Mukh...
We first benchmark our approach on a binary classification task in detecting anomalies in the ECG recordings of the MIT-BIH Arrhythmia Database52. In order for the data to be compatible with the RSNN, we first encode the continuous ECG time-series into trains of spikes using a delta-modulat...
9. Electrical capture was simultaneously verified with ECG recordings. A clear increase in heart rate and QRS complex amplitude was observed with the onset of pacing to demonstrate that the device drives the heart rhythm (Fig. 5c). Fig. 5: Electrical and optogenetic pacing capabilities. a Mouse...

the Stim-A interval at the shortest Stim-A site was significantly shorter than that at the corresponding ventricular side of earliest retrograde atrial activation. Second, during tachycardia, the interval between the onset of the surface QRS and the retrograde atrial electrogram (QRS-A interval) wa...
Non-invasive discrimination between lung squamous cell carcinoma (LUSC) and lung adenocarcinoma (LUAD) subtypes of non-small-cell lung cancer (NSCLC) could be very beneficial to the patients unfit for the invasive diagnostic procedures. The aim of this s

A total of 120 bipolar leads were analyzed from a body surface potential map (BSPM) data with 236 subjects with a normal ECG. The average and standard deviation (SD) of the QRS-complex and the P-wave amplitudes in each electrode location and for each subject were determined. The results ...
