Carotid massage for svt

A year-old women with a history of palpitations presented to the emergency department with a supraventricular tachycardia; the patient was cardiovascularly stable. Carotid sinus massage CSM was performed to help identify the underlying rhythm. During carotid massage for svt the patient had an immediate cerebrovascular accident, resulting in a left hemiplegia.

The first explanation behind the process of using a Valsalva Maneuver was described in by Hamilton et al. The pathophysiological basis of action of the four phases of the maneuver is based on the nature of increased refractoriness of AV nodal tissue, particularly on the effect of vagal activity. This occurs through increased intrathoracic pressure leading to baroreceptor stimulation, as demonstrated through the heart rate and blood pressure responses. The best available evidence currently, specifically the work of Taylor and Wong , supports the following three criteria in an evidence-based model of practice of the Valsalva Maneuver for SVT reversion in the emergency-care setting:. Patients should be instructed how to perform VM properly before attempting one.

The use of vagal stimulation to halt supraventricular tachycardia is a standard medical therapy. Two methods of vagal stimulation, the Valsalva maneuver and carotid sinus massage, have been used in urgent situations. Lim and associates compared the success rates of these two methods of vagal stimulation in terminating spontaneous supraventricular tachycardia in an emergency department setting. All patients with supraventricular tachycardia whose rhythm did not reveal obvious atrial flutter, atrial fibrillation or sinus tachycardia and who were hemodynamically stable were randomly assigned to undergo either the Valsalva maneuver or carotid sinus massage. Those who had carotid sinus massage were further randomized to undergo either right or left carotid sinus massage first. If the tachycardia was not terminated by the first method of vagal stimulation, the alternative maneuver was attempted. The Valsalva maneuver was performed by blowing into a mouthpiece with sustained resistance for 30 seconds or more. Carotid sinus massage was performed in the standard manner for 10 seconds with the head tilted to the opposite side. If both methods of vagal stimulation failed, patients were managed with pharmacotherapy or cardioversion. All patients in whom rhythm conversion occurred were monitored by continuous electrocardiography for an additional two hours.

Methods: This prospective, randomized case study was performed in the ED of a tertiary care institution. Patients with regular narrow complex tachycardia were randomly assigned to undergo either the Valsalva maneuver or CSM. If the tachycardia was not terminated by the method chosen by randomization, then the alternative method of vagal maneuver was used. If the tachycardia was not converted by both methods of vagal stimulation, patients would undergo either synchronized electrical cardioversion or a pharmacologic method of conversion at the discretion of the treating physician, depending on the patient's hemodynamic status. Results: One hundred forty-eight instances of SVT were studied Sixty-two patients underwent Valsalva maneuver first with conversion in 12 success rate of Eighty-six underwent CSM first with conversion in 9 success rate

A carotid massage, often called a carotid sinus massage or CSM, is a medical maneuver used to slow down a dangerously rapid heartbeat in patients or to diagnose certain heart rhythm disturbances. The carotid artery carries blood to the brain, and an incorrectly performed CSM can cause serious health repercussions, especially in elderly patients. Do not perform this maneuver on yourself or another person unless you are a physician. National Institutes of Health Go to source.

Patients should be instructed how to perform VM properly before attempting one. In addition, carotid massage is only recommended for select patients and may only be performed by a physician. It is essential to understand that it is not always appropriate to have a patient attempt VM. For instance, if the patient has supraventricular tachycardia and is unstable, VM may delay definitive treatment such as cardioversion. Some potential complications include dizziness and an arrhythmia originating in the ventricles.

Some potential complications include dizziness and an arrhythmia originating in the ventricles. SVT is a generic term applied to any tachycardia originating above the ventricles and which involves atrial tissue or atrioventricular AV nodal tissue. A year-old women with a history of palpitations presented to the emergency department with a supraventricular tachycardia; the patient was cardiovascularly stable. Shockable Rhythms: Ventricular Tachycardia, Ventricular Fibrillation, Supraventricular Tachycardia According to television, if there's a heart problem, you shock it, right? A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Emergency casebooks. Advanced search. If the tachycardia was not terminated by the method chosen by randomization, then the alternative method of vagal maneuver was used. Supraventricular tachycardia SVT is a common heart abnormality that presents as a fast heart rate. Lim and associates compared the success rates of these two methods of vagal stimulation in terminating spontaneous supraventricular tachycardia in an emergency department setting. More in AFP. Email alerts.

To diagnose supraventricular tachycardia SVT , a healthcare professional examines you and listens to your heart. A member of your care team takes your blood pressure. You are usually asked questions about your symptoms, health habits and medical history.

During massage the patient had an immediate cerebrovascular accident, resulting in a left hemiplegia. The only reported complication of the Valsalva maneuver is hypotension from straining. SVT is a rapid heartbeat that originates in the chambers above the ventricles. According to television, if there's a heart problem, you shock it, right? Vagal Maneuvers with Supraventricular Tachycardia Vagal maneuvers are used as a first-line management tool with supraventricular tachycardia. More in AFP. Skip to main content. If a physician ensures a patient is an appropriate candidate for VM, the patient can be instructed to perform maneuvers at home in some situations. Continue Reading. This acts to prolong refractoriness of the nodal tissue and disrupt the re-entry circuit. It is essential to understand that it is not always appropriate to have a patient attempt VM. Ann Emerg Med.
