Premature beats, as the name implies, are “premature beats”. Premature beats are the most common of the many arrhythmias. It is a symptom and not a separate disease. Premature beats can occur in organic heart disease, but they can also occur in normal people for external reasons. It can be said that premature beats occur in almost 100% of adults. Stress, excitement, fatigue, smoking, alcohol, strong tea, coffee, etc. trigger premature contractions in normal people, most of whom do not have uncomfortable symptoms or have discomfort such as palpitations, stopping, chest tightness, or fatigue. Most of these premature contractions are functional, not dangerous, and do not affect the life expectancy and daily activities of people. In addition, there is another kind of organic premature beats, which is especially common in the elderly, and is often combined with other organic heart diseases such as coronary heart disease, heart failure, cardiomyopathy, rheumatic heart disease and so on. In this case, it is not just a question of premature beats, but also the treatment of the primary heart disease. Premature beats can be a symptom of instability, and some organic premature beats are very dangerous, for example, some specific types of premature ventricular beats may degenerate into ventricular fibrillation, which can be life-threatening. If you find a high number or frequency of premature beats and feel uncomfortable, it is best to go to the hospital for the appropriate tests to determine if you have organic heart disease, and then to evaluate the frequency and duration of premature beats to determine if treatment is needed and what kind of treatment is needed.
