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...
ECG changes in ischemia are discussed in detail in section 3 (Acute & Chronic Myocardial Ischemia & Infarction) and a specific chapter discusses ST elevation in detail. The T-wave Assessment of the T-wave represents a difficult but fundamental part of ECG interpretation. The normal T-wave in ...
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...
2.2). The five basic ECG waveforms, labeled alphabetically, are the:The P wave represents the spread of a stimulus through the atria (atrial depolarization). The QRS waveform, or complex, represents stimulus spread through the ventricles (ventricular depolarization). As the name implies, the QRS...
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: ...
