What causes palpitations and shortness of breath?

If you have palpitations and shortness of breath, then we need to pay attention to the causes. Common hypoglycemia or severe anemia, as well as low blood pressure or cardiovascular dysfunction may cause such symptoms.

1. Active myocarditis: There may be symptoms such as palpitations, heart palpitations, tachycardia, arrhythmia, chest tightness and shortness of breath, which should be examined and excluded.

2. Hypoglycemia: The most common is idiopathic functional hypoglycemia, which is more common in middle-aged women. It is characterized by no clear cause of the disease. Fasting blood sugar is usually normal. It generally does not cause hypoglycemia when fasting. The attack time is usually 2 to 4 hours after a meal (11 am or 3 pm). The symptoms are mild and loss of consciousness is rare. The early symptoms of hypoglycemia include palpitations, fatigue, hunger, hand tremors, cold sweats, pale complexion, cold limbs, or nausea and vomiting; they are mainly caused by overexcitement of the sympathetic nerves and excessive adrenaline: hypoglycemia is paroxysmal, not frequent, and symptoms of chest tightness and shortness of breath rarely occur.

3. Anemia: Anemia can cause symptoms such as dizziness, palpitations, and tachycardia, but generally does not cause symptoms of chest tightness.

4. Hypotension: It also mainly causes dizziness symptoms, but blood pressure around 60/90 generally does not cause changes in blood supply.

5. Cardiovascular dysfunction: It is very common in clinical practice, and the symptoms are: patients feel chest tightness, shortness of breath, subjective feeling of insufficient air, difficulty breathing, often sighing, and feel comfortable after taking a deep breath or a long breath; sometimes it is often accompanied by palpitations, tachycardia, stabbing pain in the precordial area, as well as fatigue, dizziness, confusion, insomnia and other neurological symptoms. Symptoms are often triggered or aggravated by mental factors.
