Surgery:

For severe heart arrhythmia,  it is very imprint for the our heart or for those with an underlying cause such as a heart defect, surgery may be an option. Because the surgeries to correct heart arrhythmia are open-heart procedures that sometimes require several months for recovery, surgery is often a last-resort treatment option.
Heart defect treatments:
Some heart defects are minor and don't require treatment, while others may require regular checkups, medications or even surgery. Depending on what heart defect

you have and how severe it is, your treatment could include.

Medicine To Use:
Some mild congenital heart defects, especially those found later in childhood or adulthood, can be treated with medications that help the heart work more efficiently.Special procedures using catheters. Some people now have their congenital heart defects repaired using cauterization techniques, which allow the repair to be done without surgically opening the chest and heart. In procedures that can be done using cauterization, the doctor inserts a thin tube (catheter) into a leg vein and guides it to the heart with the help of X-ray images. Once the catheter is positioned at the site of the defect, tiny tools are threaded through the catheter to the heart to repair the defect.
Open-heart surgery. In some cases, your doctor may perform open-heart surgery to try to repair your heart defect. These surgeries are major medical procedures and sometimes require a long recovery time. It's possible you'll need multiple surgeries over several years to treat the defect.
