Early symptoms of premature heart attack are not typical, some may have no clinical symptoms, while others may show obvious palpitations (rapid heartbeat, often accompanied by panic), and frequent premature beats may also show symptoms such as fatigue and dizziness. 1. Early symptoms of premature heart disease are related to the number of premature beats. If only a few premature beats occur occasionally, there will be no corresponding symptoms. At this time, the electrocardiogram is also completely normal, generally do not need special treatment can be restored. 2. If there are frequent episodes of premature heart beats, or if there are frequent premature beats in duplex or triple rhythm, then the patient will have obvious symptoms of panic and palpitations (rapid heartbeat, often accompanied by panic). When these symptoms occur, a timely electrocardiogram (ECG), especially a 24-hour ambulatory electrocardiogram (EKG), can quickly capture the abnormality, which can be treated with medication or radiofrequency ablation (RF ablation). In addition, premature heart beats can also be associated with angina pectoris, swelling of the lower extremities, and nocturnal paroxysmal dyspnea. Patients with this type of heart attack have a history of organic heart disease, and need to go to a healthcare facility for further diagnosis and treatment.
