The system utilizes the R-wave trigger signal from murine electrocardiography. Image data are acquired in either the block scanning mode or the line scanning mode. In block scanning, murine cardiac images in systole and diastole can be retrospectively reconstructed with a short data acquisition time...
Finally we described the utility of a careful evaluation of P wave duration and dispersion measured on standard ECG and signal-averaged ECG (SAECG) recordings as potential atrial fibrillation predictors and markers of history of paroxysmal atrial fibrillation....
Laboratory examinations revealed 1st grade block in ECG, the irregular basic rhythm and sporadic spikes in EEG. The GI tract showed malrotation of intestine, and atrophy of brain and relative dilatation of ventricles were seen in computed tomography scanning. The karyotype of the patient was 46,XY...
Explain the following waves and intervals: P-wave, P-R interval, QRS wave, S-T segment, QT interval and T wave. Fill in the blank. The total volume of blood discharged from the ventricles per minute is called ___. Fill in the bla...
Successful ventricular rapid pacing appears in the ECG tracings, as indicated by a narrow QRS that converts to a wide QRS with shortened R–R intervals. Use of a device with programmable pacing voltage via primary transmission coil RF output power modulation allowed for further studies. On day...
Testing the application can be done in real-time using the Hi-wave debugger built into the CodeWarrior IDE. This tool allows non-intrusive debugging through the microcontroller's BDM pin while the processor is running. Using the Hi wave debugger will allow you to set breakpoints, step though ...
Continuous recording of T body, HR and T ambient of a hibernating dormouse. ECG-pattern (P to T-wave) is decelerated from normothermia to deep hibernation. Graphic used with permission. The dormice were housed in a wire-meshed cage placed inside a climate chamber. Ambient temperatures varied...
,R.,... - 《Medical & Biological Engineering & Computing》 被引量: 158发表: 1980年 A QRS complex detection algorithm using electrocardiogram leads A QRS complex detection algorithm was developed using the available leads of the electrocardiogram (ECG). This detector is based on the combination ...
Central venous catheters—the inability of 'intra-atrial ECG' to prove adequate positioning BACKGROUND: The classic increase in P wave size, known as 'P-atriale', is a widely accepted criterion for determination of proper positioning of central ve... W Schummer,C Schummer,C Schelenz,... ...
Utilize equipment that will give you the most information with least problems, for example, ultrasound Doppler probe for heart rate and rhythm, end-tidal capnography, and ECG are easy to use. Pulse oximetry can be temperamental but still useful when a reliable pulse wave is obtained (irregular ...
