- The ECG typically shows that the lead T wave that leads up from the QRS main wave decreases or is flat, but the direction is still upright. In the future, the ST segment gradually sags and protrudes slightly downward, and the T wave turns into a negative and a positive two-way direction. The ST segment and the T wave inverted part are connected together, and the boundary cannot be distinguished; in the end, the T wave is completely inverted and only ends The terminal part leaves a terminal erect T wave that slightly exceeds the equipotential line, and the QT interval is shortened. In this way, the ST segment and T wave of the QRS main wave upward form a fishhook-shaped waveform with slightly longer forelimbs, oblique drooping, short hind legs, and a sudden rise; the ST segment of the QRS main wave downwards is mild Raising upward, the T wave is positive and negative. The appearance of these changes is merely a sign of digitalis application and does not imply an overdose or poisoning. If there is no other indication, the drug does not need to be stopped.
