你好，
心律失常是心臟生物電場的生理物理功能問題，因此，不是生物化學產品（藥物）可以解決的。
特別提示心律失常患者勿采用射頻消融術，即——采用切斷心臟電流傳導通路（神經）制止心律失常癥狀是錯誤的——到今天為止無一例康復案例。
臨床治愈心律失常目前只有兩種生物醫學工程學的成熟技術產品，你的問題可以選擇其中一個治療技術方法：
1、處于早期、中期、惡性心律失常初發階段的心律失常患者，應用細胞基因能量治療儀——即可完全控制、或治愈。 確保療效：20天內如無顯效產品召回。
2、已經處于惡性心律失常中、晚期患者，可以在三甲醫院佩戴心臟起搏器（或除顫器）——即可充分控制心律失常病癥，可保患者心臟正常。

你多大歲數？建議做個心臟彩超、肌鈣蛋白吧，除外一下心肌炎，心肌炎包括心律失常型，可導致各種類型的心律失常。
