Patient: Dear Director Wu: Since my father had his aortic aneurysm root resection and ascending aortic valve replacement (mechanical valve) on April 8, 2009 at the Cardiovascular Surgery Department of Beijing Fu Wai Hospital, his body has been recovering quite well, and his oral warfarin international standard values are basically within the normal range, but recently the sound of the mechanical valve beating inside the heart at night is extremely abnormal. The sound of the heart beating is fast and slow, and sometimes there is a pause (the heart almost stops beating within a few seconds), panic, fibrillation, heart shaking is very strong, at this time my father will be particularly uncomfortable, then oral valium to slowly ease (will fall asleep) recently in the local hospital to do an electrocardiogram and cardiac ultrasound doctor said also abnormal, the doctor said my father just nine months after surgery why would such a situation arise? Recently my father is extremely upset and very scared, Director Wu, your medical skills are so superb that you must know what my father can do to rule out such pain? What medication should I take to make my father’s heart stop feeling bad? Thank you! I look forward to hearing from you! Doctor: Hello patient, the problem you describe is mainly arrhythmia, you need to do an electrocardiogram to check what the specific problem, if necessary, 24-hour electrocardiogram test to find out the cause, if there is no such problem early after surgery, it should be unrelated to the surgical operation, it is recommended to go to the Department of Internal Medicine electrophysiological examination in Fulbright Hospital! Patient: Dear Director Wu: I just opened my computer and saw your reply, it was like seeing sunlight in the darkness. Is it a serious problem? We will definitely take your advice and prepare for a trip to Fulbright Hospital after this year. Director Wu, what should I do if my father has this condition for the time being? Thank you! The patient is having frequent atrial premature beats, which is not uncommon after valve surgery, some valve disease, especially rheumatic valve disease patients, will have this type of condition before surgery, and may also develop into atrial fibrillation, there are many patients with rheumatic disease combined with atrial fibrillation in China, simple valve replacement surgery can not remove atrial fibrillation, the patient if tolerated atrial fibrillation, daily life is not very affected. If the palpitation symptoms are obvious, you can choose treatment such as cardiac diuresis, and you can also add anti-arrhythmic drugs according to the function of the heart. The specific in hospital consultation, by the doctor prescribed medication! I hope the patient gets well soon!
