The dangers of inverted heart t wave

The heart can be said to be the most important organ in our human body. If the human body is compared to a precision instrument, the heart is the core energy source of this instrument. This undoubtedly describes the importance of the heart vividly. Inverted heart T wave is a manifestation of cardiac ischemia, which is harmful to the human body. When this phenomenon occurs, timely measures should be taken in terms of diet, psychology and exercise. The following is an introduction to its hazards.

The dangers of inverted heart T waves :

1. Dizziness, especially sudden dizziness.

2. Body numbness, sudden numbness on one side of the face or hands and feet, or tongue or lips.

3. Temporary slurred speech or difficulty speaking.

4. Limb weakness or inability to move.

5. Headache that is different from usual.

6. Sudden unexplained fall or fainting.

7. Brief loss of consciousness or sudden changes in personality and intelligence.

8. Obvious general fatigue and weakness of limbs.

9. Nausea, vomiting or blood pressure fluctuations.

10. Feeling drowsy and sleepy all day long - lethargy.

11. Involuntary twitching of one side or one limb.

12.Sudden but temporary blurred vision

Inverted heart T waves are related to myocardial ischemia. Long-term myocardial ischemia may cause myocardial infarction or heart failure. It is recommended to eat a light diet, avoid high-salt and high-fat foods, maintain an optimistic attitude and get enough sleep, avoid strenuous exercise, and use anti-myocardial ischemia drugs for treatment.

Clinical electrocardiogram manifestations:

1. Epicardial ischemia - T wave inversion In subepicardial ischemia, the T wave vector points away from the epicardial surface and toward leads V4 and V5. T waves are inverted in these leads and their adjacent leads, showing bilateral symmetry and arrow-like changes. T wave inversion may occur alone or in combination with ST segment and U wave abnormalities. That is, if ST segment depression and symmetrical inversion of the T wave exist simultaneously in the same lead (V4, V5), it indicates both subendocardial damage and subepicardial ischemia. T wave inversion in lead V5 often occurs late, usually a few minutes after the exercise test is completed, and lasts for a long time, sometimes up to 40 minutes and is accompanied by prolonged Q-Tc.

2. Single T wave inversion often indicates coronary artery insufficiency when it occurs in the following situations: ① The inverted T wave is obviously arrow-shaped and symmetrical, and the ST segment stays on the isoelectric line for a long time (>0.12 seconds); ② The Q-T interval is prolonged; ③ The degree of T wave inversion after exercise is greater than the electrocardiogram record of hyperventilation for 30 seconds in standing and at rest; ④ The T wave inversion after exercise is accompanied by a relatively slow heart rate; ⑤ T wave inversion occurs in lead I (indicating an increase in the QRS-T angle). When the inverted T wave is accompanied by ST segment depression, this inverted T wave often appears later, that is, the T wave inversion occurs after the ST segment depression, that is, when the ST segment depression after exercise has disappeared or is disappearing, the T wave inversion appears.

3. Physiological T wave inversion T wave inversion is sometimes a normal physiological reaction caused by exercise, and its characteristics are: ① The T wave is an asymmetric arrow-like change; ② There is no Q-T interval prolongation; ③ The ST segment does not stay on the baseline for a long time; ④ The depth of T wave inversion is <0.2mV. Physiological T wave inversion is seen in the following factors: ① excessive ventilation; ② increased sympathetic nerve tension; ③ the impact of tachycardia on the myocardium; ④ the normally wide QRS-T angle becomes wider. At this time, the electrocardiogram has the following characteristics: the calm electrocardiogram has a higher R wave accompanied by a lower T wave.

treat

(1) Adjust your diet appropriately: eat less high-fat foods and eat more fruits, vegetables, and soy products.

(2) Moderate physical activity.

(3) Quit smoking and drinking.

(4) Pay attention to the combination of work and rest, avoid staying up late, and ensure adequate sleep.

2. Treat the primary disease that causes myocardial ischemia.
