Introduction
In general, the severity of chest tightness caused by heatstroke needs to be determined based on specific symptoms and circumstances. If discomfort occurs, timely medical attention is recommended. Once chest tightness appears, activities should be stopped immediately, and the individual should be moved to a cool, well-ventilated area. Clothing should be loosened, and measures taken to lower body temperature. Additionally, an appropriate amount of cool, salt-containing beverages should be consumed to replenish fluids and electrolytes.

Generally speaking, whether chest tightness caused by heatstroke is serious depends on the specific symptoms and circumstances. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:

If chest tightness after heatstroke is accompanied by symptoms such as high fever, absence of sweating, confusion, coma, or convulsions, the condition is likely severe. This may indicate heatstroke, a condition in which the body's temperature regulation mechanism fails. If not treated promptly, it can cause severe damage to multiple organs and even threaten life.

If only mild chest tightness occurs after heatstroke, with no significant rise in body temperature and no other severe discomfort, and if symptoms gradually subside after moving to a cool place, replenishing fluids, and resting, the situation is usually relatively mild. This is often caused by temporary oxygen deficiency or electrolyte imbalance due to heatstroke, and generally does not lead to serious consequences if treated promptly.

Once chest tightness occurs, stop all activity immediately, move to a cool and well-ventilated area, loosen clothing, and take measures to cool down. At the same time, drink salted cool beverages in appropriate amounts to replenish fluids and electrolytes. Closely monitor any changes in symptoms. If symptoms continue to worsen or if high fever or altered consciousness develops, call emergency services immediately and seek prompt professional medical treatment. During hot weather, take precautions against heatstroke and avoid staying in high-temperature environments for prolonged periods.

What causes dizziness, blacking out, and fainting when standing up from a squat? What should I do?
Arrhythmia, an abnormal heart rhythm caused by disordered electrical activity in the heart, reduces cardiac output. This insufficiency worsens during postural changes such as squatting to standing, leading to inadequate cerebral blood supply and resulting in dizziness or fainting. Symptoms often include palpitations, chest tightness, and shortness of breath; severe cases may be life-threatening. Treatment, under medical supervision, includes antiarrhythmic medications such as propafenone hydrochloride tablets, metoprolol tartrate sustained-release tablets, and amiodarone tablets to restore normal heart rhythm.

Approximately how many heartbeats per minute before exercise?
When the heart rate is between 60 and 100 beats per minute, it indicates a stable cardiovascular system and that the body is in an appropriate baseline state for physical activity, capable of handling initial exercise load changes. Exercise can be performed normally under this condition, provided adequate warm-up is done beforehand. If the heart rate persistently falls below 60 beats per minute and is accompanied by chest tightness and fatigue, it may indicate abnormal cardiac conduction function.

What does it mean when cardiac enzymes are elevated?
In general, elevated cardiac enzymes often indicate possible injury or necrosis of myocardial cells, or may reflect fluctuations in markers caused by damage to other tissues or organs. Myocardial cell injury is the primary cause of elevated cardiac enzymes. When the myocardium is damaged due to ischemia, inflammation, or other factors, cardiac enzymes inside the cells are released into the bloodstream, leading to increased levels. This is often accompanied by symptoms such as chest pain, chest tightness, and palpitations.
