Premature cardiac contractions, or preterm contractions, can be asymptomatic or present with symptoms such as palpitations; the main danger of premature cardiac contractions is that they can evolve into life-threatening conditions such as atrial fibrillation.
The main danger of premature contractions is that they can lead to life-threatening conditions such as atrial fibrillation. If preterm contractions occur frequently, they can trigger or aggravate angina pectoris and heart failure. In some cases, frequent attacks may cause severe anxiety and insomnia.
Although most of the pre-systolic contractions have no clinical significance if they occur in people with normal or no organic heart disease. However, if it occurs in acute myocardial infarction, cardiomyopathy, etc., it can evolve into fatal ventricular tachyarrhythmia, which can jeopardize the patient’s life. At the same time, multiple preterm contractions can be a prelude to atrial fibrillation and should be taken seriously.
If you feel sick, we recommend that you seek medical attention in a timely manner.
