Carotid Sinus Massage
In settings where a medical professional is present and an affected individual experiences a PSVT episode, a carotid sinus massage may be able to treat their symptoms. The carotid sinus is a spot of local swelling in the carotid artery that manages and adjusts an individual's blood pressure at times when it becomes too high or low. This type of massage is performed by placing pressure with a circular motion on the carotid sinus for approximately ten seconds. This technique should only be used when administered by a physician and with monitoring of the patient's heart rate and blood pressure throughout. This maneuver is used to stimulate a decrease in heart rate at times when an individual has symptoms to produce an effective interruption and termination of the episode. Not all PSVT patients are good candidates for this type of maneuver. Individuals also affected by chronic hypotension, carotid arterial stenosis, history of blood clots, and a history of smoking should not use this method as a treatment for their symptoms.
