Palpitations and panic are actually different terms for the same clinical manifestation. Palpitations is a medical term, and panic is another way of describing this uncomfortable symptom for the general public. Both are essentially the same, and are used to describe the discomfort of uneven heartbeat. The causes are mainly the following: 1, physiological factors: nervousness, fear, excessive hunger leading to hypoglycemia, may lead to the symptoms of panic, that is, palpitations; 2, non-cardiogenic diseases: such as hyperthyroidism, fever, infection, rheumatic immune diseases and severe anemia, hypertension, etc., will lead to such phenomena as a faster or slower heartbeat, inducing palpitations and panic symptoms in patients; 3, cardiogenic diseases : Various types of arrhythmias and arrhythmias are common clinical causes of palpitations and panic, such as sinus tachycardia or supraventricular tachycardia, premature atrial beats, premature ventricular beats, atrial fibrillation, etc., which induce subjective feelings such as palpitations and panic in patients due to fast or irregular heartbeat. In addition, bradycardia occurs, and patients may also feel uncomfortable with palpitations on their own. In other cardiogenic diseases, such as coronary artery disease and acute attack of myocardial ischemia, patients may also experience palpitations and discomfort in addition to symptoms of chest pain.
