PT waveDynamic programmingDetection and tracking of the P- and T-waves are important issues in the analysis and interpretation of the ECG signals. This paper addresses the problem by using two mixture Gaussian function and the Dynamic programming. A key feature of the proposed algorithm is that ...
Medical physics: Explaining the T-wave shape in the ECG Nature(IF50.5)Pub Date : 2000-01-01, DOI:10.1038/47409 Diego di Bernardo , Alan Murray The heartbeat is recorded on an electro- cardiogram (ECG) as a characteristic trace determined by changes in the electrical activity of the heart...
The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex. The PR interval is assessed in order to determine whether impulse conduction from the atria to the ventricles is normal. The flat line ...
Use peak detection algorithms like the Pan-Tompkins algorithm or findpeaks function in Matlab to detect the R peaks. Once you have the R peaks, you can identify the Q and S points around the R peak based on specific criteria (e.g., slope changes). P and T Wave Detection: To detect t...

Fill in the blank: Normally, the T wave on an ECG has a positive deflection of about ___ mV. T Wave: In an electrocardiogram, the T wave represents ventricular repolarization. Ventricular polarization refers to when the muscle cells of the ventricles contract to pump...
T-wave corresponds to the phase of rapid repolarization of the ventricular action potential. In the 12-lead ECG of adults, the normal T-wave is inverted in aVR; upright or inverted in leads aVL, III, and V1; and upright in limb leads I, and II, and in V3 to V6. Sometimes also ...

In the ECG of a diabetic patient without coronary artery disease, a double T wave was observed. The ECG was normal the next day.
