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 ...
Essay on How Ekg Works At the latter end of the p-q interval, atrial contraction occurs forcing additional blood into the ventricles. At the beginning of the QRS interval on an ECG reading, the mitral valve closes and the ventricles are at EDV (135ml). During the QRS interval, ventricular...

T-wave alternans A repolarisation phenomenon manifesting as a microvolt beat-to-beat change in the amplitude of the T wave and ST segment on EKGs. T-wave alternans has low specificity as a predictor of arrhythmic risk in unselected populations with prior myocardial infarction. Segen's Medical...

Some of the T-waves is the same height. I suggest making some sort of delay, so that the counter won't count until 0.3 seconds have passed since that is the maximum speed of the heart beats, and any peak within this time must be a t-wave. Can anybody help with this?
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: ...
What does the T wave on an ECG correspond to? What is the cardiac cycle? The events related to one heartbeat. The total amount of time if takes for one drop of blood to travel through the heart. The number of beats of the heart per minute. The events related to the flow of blood...
However, it represents an artifact called “pseudo double T wave”. The cause is unknown but most likely due to abnormalities at the interface between surface electrodes and skin tissue. The diagnosis of ECG artifacts requires meticulous examination of the tracings coupled with a thorough knowledge...
Wellens' syndrome is characterized by T-wave changes in electrocardiogram (EKG) during pain-free period in a patient with intermittent angina chest pain. It carries significant diagnostic and prognostic value because this syndrome represents a pre-infarction stage of coronary artery disease involving pro...
