Premature beats, also known as preterm contractions, are heartbeats caused by an abnormal pacing point in the heart that occurs before a normal heartbeat is emitted. Currently, the causes of premature beats include non-disease factors and disease factors.
1. Non-disease factors: These include individual factors and drug factors.
(1) Individual factors: For example, drinking alcohol, staying up too late, and being overstressed may trigger premature beats.
(2) Drug factors: such as digitalis, sympathomimetic drugs, etc., can also trigger premature beats.
2. Disease factors: including diseases of the heart itself and diseases of the endocrine system.
(1) Diseases of the heart itself: for example, coronary heart disease, myocarditis, heart failure, valvular heart disease, etc., which can cause premature beats.
(2) Diseases of the endocrine system: mainly hyperthyroid heart disease. In addition, anemia and electrolyte disorders can also induce premature beats.
Patients should go to the cardiovascular department in time to determine the cause of the disease under the guidance of the doctor to take appropriate treatment programs, not blindly use drugs.
