An S wave in ECG lead V-6 predicts poor response to updates cardiac resynchronization therapy and long-term outcomeCLBBBCRTCRT responseHeart failureQRS morphologyBACKGROUND Cardiac resynchronization therapy (CRT) is a standard treatment for selected patients with chronic heart failure (HF). However, ...

(FIR) bandpass process, the respiration and heartbeat signals of the subject can be obtained. The theory of respiration and heartbeat detection is illustrated in Supplementary NoteS5. Since the main lobe of EM wave radiated by metasurface is only facing one of the subjects each time, ...

Last year the Federal Aviation Administration (FAA), changed the electrocardiogram (ECG) markersthat measure the ‘PR interval’.This is the time it takes for an electrical impulse to travel from one part of the heart to another and is an indicator of heart health. The new limit is 50 per...
For the EEG mode, 5-scale discrete wavelet transforms (DWT) were applied to each of the 25 channels to obtain five rhythms, that is, theδwave (0–3.9 Hz);θwave (3.9–7.8 Hz);αwave (7.8–15.6 Hz);βwave (15.6–31.3 Hz); andγwave (31.3–62.5 Hz)14....

Another analysis method finds the time shift at which both curves have the highest correlation; however, this can be affected by the correlation window and presence of wave reflections starting from the systolic downslope [150]. Instead of relying on phase-contrast acquisitions in two slices, PWV...
NSTEMI with T wave Inversion NSTEMI with Biphasic T wave NSTEMI with normal ECG The irony called STEMI evolving as NSTEMI** By default most of us think , if it is NSTEMI . . . there must be ST depression. This thinking is not logical but traditional. Still, ST depression may be the ...
