Cats with sustained SVT or signs of congestive heart failure should be hospitalized immediately. There they may undergo a variety of non-pharmacologic, emergency interventions, including vagal maneuvers, precorial thump, and/or electrical cadioversion. Delivering a precordial thump is often successful in terminating an SVT, but may break the ryhtym for only a brief period.
To perform a precordial thump, the cat is placed on its right side and then "thumped" in the affected region with a fist while recording the EKG.
Your veterinarian will schedule follow-up appointments for your cat as needed for treating the SVT and/or the underlying heart disease with prescription medication and/or dietary changes. He or she will recommend that you feed your cat a low sodium diet as well as restrict its activity until further notice.
