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...
Electrocardiogram (ECG) interpretation and measurement is an essential aspect of patient safety and pharmacovigilance in clinical trials. Changes in the T wave segment of an ECG can provide both diagnostic and prognostic information and may be affected by a variety of intrinsic and extrin...
ECG interpretation traditionally starts with an assessment of the P-wave. 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...
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 ...

To detect the P wave, you can search for the local maximum before the R peak. For the T wave, look for the local maximum after the R peak. Here is a simplified example of Matlab code to detect the P, Q, R, S, T points on an ECG waveform: ...
In the ECG of a diabetic patient without coronary artery disease, a double T wave was observed. The ECG was normal the next day.
The T-wave of the ECG occurs during the later phase of diastole. a. True. b. False. Cardiac Cycle: The cardiac cycle includes mechanical and electrical activities associated with a single heartbeat. Systole refers to periods of contraction; diastole refers to periods o...
Background: T wave inversion (TWI) has been described in a variety of clinical conditions, usually resolving in a timely manner after the index event. TWI has also been considered a robust sign of myocardial reperfusion appearing early after successful revascularization via fibrinolysis or percutaneous...
