Hi, Supraventricular tachycardia (SVT) is a condition where the heart rate becomes abnormally fast due to a problem with the electrical system of the heart. Exercise-induced SVT can be triggered by physical activity, particularly high-intensity exercise. Treatment for SVT may include medications, catheter ablation, or electrical cardioversion. If you have a history of exercise-induced SVT, it is important to speak with your healthcare provider before embarking on any strenuous activity, especially at high altitudes. Your healthcare provider may recommend additional tests, such as an exercise stress test or a Holter monitor, to assess your heart s response to exercise and to identify any potential triggers. In terms of remedies, there are some things you can do to potentially reduce the likelihood of SVT episodes during exercise, including: - Gradually increase your exercise intensity over time to avoid sudden spikes in heart rate. - Stay well hydrated before, during, and after exercise. - Consider using a heart rate monitor during exercise to help you stay within a safe heart rate range. - Avoid exercise in extreme temperatures, as this can put additional stress on the heart. - Discuss the use of medications with your healthcare provider, as certain medications may help prevent SVT episodes during exercise. - Consider incorporating relaxation techniques such as deep breathing or meditation to help manage stress, which can be a trigger for SVT. It is important to remember that while exercise-induced SVT can be concerning, it is typically not life-threatening. However, it is still important to work closely with your healthcare provider to develop a plan for managing your condition and ensuring your safety during exercise. Take care.
