What is palpitation and shortness of breath?

In recent days, I have always been flustered, short of breath and chest tightness. First of all, we must rule out pathological and organic reasons. Common reasons are as follows:

1, active myocarditis: symptoms such as palpitation, palpitation, tachycardia, arrhythmia, chest tightness and shortness of breath should be checked and excluded.

2. Hypoglycemia:

The most common is idiopathic functional hypoglycemia, which is characterized by middle-aged women. There is no definite cause of this disease. Fasting blood sugar is normal, and generally does not cause hypoglycemia attack when fasting, but the attack time is often after meals.

2~

4 hours (165438+ 0 am or 3 pm), the early symptoms of hypoglycemia are palpitation, fatigue, hunger, shaking hands, cold sweat, pale face, cold limbs, or nausea and vomiting. Mainly caused by excessive excitement of sympathetic nerve and adrenaline:

Hypoglycemia is paroxysmal, not recurrent, and there are fewer symptoms of chest tightness and shortness of breath.

3, anemia:

Anemia can cause dizziness, palpitation, tachycardia and other symptoms, but generally does not cause chest tightness.

4, low blood pressure:

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

5, cardiovascular dysfunction:

Common clinical symptoms include: patients feel chest tightness and shortness of breath, subjective feeling of insufficient breath, poor breathing, sighing, deep breathing or feeling comfortable after breathing; It is often accompanied by nervous system symptoms such as palpitation, tachycardia, precordial tingling, fatigue, dizziness, confusion, insomnia, etc., which are often induced or aggravated by mental factors, and may also be accompanied by chronic pharyngitis such as foreign body sensation in the pharynx.

Patients often feel obvious symptoms, but ECG, B-ultrasound and chest X-ray examination have no organic findings.

The pathogenesis of this disease is a series of functional symptoms and manifestations of cardiovascular system caused by autonomic nerve dysfunction and increased sympathetic nerve tension.

Check:

It is suggested to do ECG, B-ultrasound, myocardial enzyme, chest X-ray, blood routine and blood sugar examination. If you have fasting hypoglycemia, you should further do pancreatic B-ultrasound.

Ultrasound or CT examination ruled out hypoglycemia caused by pathological reasons.

Cardiovascular dysfunction should be considered if cardiopulmonary disease or hypoglycemia can be ruled out after examination.
