What's the reason for the sudden panic?

Sudden onset of palpitations can be divided into two types: physiological and pathological. Palpitations may occur after intense exercise or drinking a lot of alcohol. It may also be due to pathological reasons. For example, high blood pressure, anemia, heart disease and other diseases can cause sudden palpitations. If you often experience palpitations, it is best to go to the hospital for examination.

Common causes

1. Increased heart rate

1. Physiologically, normal people may experience palpitations after strenuous physical activity or mental excitement, drinking alcohol, or taking drugs such as ephedrine, caffeine, and adrenaline, which may also increase the heart rate.

2. Pathological causes include ventricular hypertrophy (such as rheumatic, hypertensive, coronary artery sclerosis, etc.), anemia, high fever, hyperthyroidism, and other diseases that cause increased cardiac output, all of which can cause palpitations.

(ii) Arrhythmias such as tachycardia or bradycardia (such as high-degree atrioventricular block, etc.) and irregular heart rhythm (such as premature beats, atrial fibrillation, etc.) can cause patients to experience palpitations.

(III) Cardiac neurosis is a clinical syndrome caused by autonomic nervous system dysfunction, which leads to cardiovascular dysfunction. In addition to palpitations, patients also have stabbing or dull pain in the left chest, difficulty breathing, and are often accompanied by other neurotic symptoms.

Key points of consultation

When seeing a doctor, pay attention to the time when the palpitations occur, its relationship with labor, and the accompanying symptoms.

(1) Palpitations accompanied by chest pain can be seen in coronary artery ischemia, myocarditis, cardiac neurosis, etc.

(ii) Palpitations accompanied by fever can be seen in rheumatic fever, hyperthyroidism, pericarditis, myocarditis, infective endocarditis and other febrile diseases.

(III) Palpitations accompanied by syncope and convulsions may be seen in cardiogenic cerebral hypoxia syndrome caused by high-degree atrioventricular block, ventricular fibrillation or paroxysmal ventricular tachycardia and ventricular fibrillation.

(IV) Palpitations accompanied by dyspnea can be seen in acute myocardial infarction, heart failure, severe anemia, etc.
