Sinus rhythm and premature ventricular contractions are mild and generally do not require surgery, but serious conditions need to be scheduled for surgical treatment as soon as possible. 1. Sinus rhythm: also known as sinus arrhythmia in clinical practice, if the heart rate is not less than 50 beats per minute, and the symptoms are not obvious, generally no special treatment. When the heart rate is lower than 40 beats per minute, with symptoms of panic and shortness of breath, surgery is generally not considered, and you can choose to take atropine and ephedrine to elevate the heart rate. However, if the effect of medication is not good, or if the patient has multiple cardiac arrests, fainting, etc., timely surgery is needed to install an artificial pacemaker. 2. Ventricular premature beats: also a kind of arrhythmia, if it is only simple ventricular pre-systole, and the frequency of the attack is relatively low, the symptoms are not obvious, no other complications, can not do special treatment, regular observation can be done, but in time to give up smoking, quit drinking, avoid drinking coffee, strong tea and so on. For the more serious condition, accounting for a larger load of the total number of heart beats, combined with other organic diseases or cardiac function is impaired patients, can consider doing transcatheter radiofrequency ablation treatment. Regarding the specific treatment options for sinus rhythm and premature ventricular contractions, they should be chosen in accordance with the individual’s situation as well as the progress of the disease, and it is recommended to consult with your local doctor if you have any questions about the treatment.
