Conversion of LBBB to normal QRS complexes determined on ECG Immediately after CRT-D implantation.
The first phase of the QT interval determination was finalized by labeling the starting points of QRS complexes.
The easiest way to calculate the ventricular rate is to count the number of QRS complexes and multiply by 6 (most ECGs are recorded at 25 mm/s = 10-second recording).
The P waves characteristically traveled into and beyond the QRS complexes, as described in the dog and cat.
In the proposed and developed methodology has been used AECG signal from the mother's abdomen where the algorithm must have the capability of processing the AECG signal and continuously detect the maternal and fetal QRS complexes.
For heart rates ranging from 60 to 100 beats per minute, a QT interval is normal if it is less than half the distance between these two QRS complexes (Normal QT=<?
The shock success rate--eradication of ventricular fibrillation after the first shock and restoration of an organized rhythm marked by at least two QRS complexes within 5 seconds--was 69% with biphasic waveform defibrillation and 45% with monophasic.
The shock success rate--defined as eradication of ventricular fibrillation after the first shock and restoration of an organized rhythm marked by at least two QRS complexes within 5 seconds--was 69% in patients undergoing biphasic waveform defibrillation and 45% with monophasic.
