There are many reasons for heartburn and rapid heartbeat, mainly physiological factors and pathological factors. Under the influence of emotional excitement, stress, exertion, strenuous activity, and dietary factors, it is normal to have a rapid heartbeat. However, if there are often unexplained panic attacks, it is recommended to have an examination as soon as possible to clarify the cause and severity of panic attacks and rapid heartbeat. Under the influence of emotional excitement, tension, anxiety, as well as staying up late, exertion and strenuous activities, the human body may activate the sympathetic nerves and release more neurotransmitters, which may act on the adrenal glands, leading to increased secretion of hormones from the adrenal glands, such as adrenaline, norepinephrine and dopamine, and these endocrine hormones will act on the cardiovascular system, causing a faster heartbeat, increased myocardial contraction and peripheral vasoconstriction. These endocrine hormones act on the cardiovascular system, causing increased heart rate, increased myocardial contraction, peripheral vasoconstriction, etc., which may induce panic and rapid heartbeat, a protective physiological response to external stress. In addition, the consumption of drinks containing excitatory effects, such as a large amount of alcohol, strong tea or coffee, will also lead to excessive excitement of the central nervous system, resulting in panic and rapid heartbeat. Second, pathological factors 1, cardiogenic diseases: for example, coronary angina, myocarditis, hypertension, or various types of tachyarrhythmias, such as common frequent ventricular premature beats, frequent atrial premature beats, as well as atrial fibrillation, atrial flutter and other types of tachycardia. Very few patients may experience short bouts of ventricular tachycardia, which may also induce panic and a feeling of rapid heartbeat. 2. Non-cardiogenic diseases: hyperthyroidism causes the body to secrete large amounts of thyroid hormones, which can cause rapid heartbeat and produce a feeling of panic. In addition, hypoglycemic episodes, pheochromocytoma, etc. may also induce panic and rapid heartbeat; 3, psychosomatic diseases: anxiety disorders, depression or neurosis, etc. may also induce panic and rapid heartbeat feeling.
