Hi angelicarys10 in Chicago, IL. Thank you for your history and for your question regarding whether a heart condition called inappropriate sinus tachycardia is dangerous for you during brachioplasty (arm lift). This is a better question to ask your internist or, better yet, your cardiologist. Your cardiologist may want to run additional cardiac testing, such as a stress test or an echocardiogram. Usually, the brachioplasty (arm lift) is performed under general anesthesia. However, the arm lift can be performed under IV sedation, if necessary. However, the final decision regarding whether you can undergo an arm lift should rest with your cardiologist. Good luck. I hope I have answered your question regarding the fact that you have a heart condition called inappropriate sinus tachycardia, and could this be dangerous for you if you have an arm lift? Since an arm lift can be a challenging surgery, please seek an experienced, board-certified plastic surgeon with significant experience performing these types of lifts. Do your research. Ensure they have performed at least 150 arm-lift procedures. Ensure they have the before-and-after pictures to substantiate it. Carefully examine their before-and-after images and review their RealSelf reviews. Sincerely, Dr. Katzen, MD, MBA, FACS, FICS ( Plastic Surgeon, President of the American Society of Bariatric Plastic Surgeons, certified by the American Board of Plastic Surgery, Fellow of the International Society of Aesthetic Plastic Surgery, American College of Surgery, International College of Surgery, and American Board of Metabolic and Bariatric Surgery, and member of the American Society of Plastic Surgery, American Academy of Cosmetic Surgery and RealSelf Hall of Fame.)
