The treatment of supraventricular tachycardia depends on the specific situation, and is generally divided into emergency episodes and non-episode treatment. Acute attack: 1. The first attack can be self-monitoring pulse, that is, heartbeat, to see if it is neat and regular, and at the same time as far as possible to the nearest hospital to do a general electrocardiogram to confirm supraventricular tachycardia, but also to provide information for the next step of treatment. For patients with multiple episodes, experience should be better, but it is also better to have an ECG to clarify, because sometimes the feeling is not always accurate. 2. Termination of supraventricular tachycardia (that is, interference with this foldback loop by different means so that the electrical activity of the heart no longer goes around in circles repeatedly): (1) neurostimulation method: not recommended for patients with a first attack, and for patients with a first attack it is recommended to have an ECG to confirm it first! The neurostimulation method also means to affect the electrical activity conduction function of the heart by stimulating some vegetative nerves of the heart, which can achieve effective termination of tachycardia in some patients, and is non-invasive and more economical for patients with brief episodes. For patients with multiple episodes, if the tachycardia cannot be terminated after 3-5 repeated attempts, a hospital visit is recommended. Neurostimulation methods are performed by raising the vagus nerve tone, and the specific methods can be as follows: a. Breath holding: after deep inhalation, hold it hard until you can’t hold it, then exhale, and so on; or conversely, exhale and hold it until you can’t hold it anymore. b. Inducing nausea and vomiting: use other objects such as fingers or chopsticks to stimulate the back wall of the throat to cause nausea and vomiting and other reflexes; c. Cold Water immersion of the face; similar to breath-holding, only with the help of a little cold water stimulation. (2) Drug termination: intravenous drugs are generally used to terminate tachycardia, which can only be done in the hospital and also requires electrocardiogram confirmation before further drug administration. Commonly used intravenous drugs include adenosine, isoptin (verapamil), cardioplegia (propafenone), and cortolone (amiodarone). (3) Esophageal pacing: The electrical impulses are delivered through electrodes to redirect the tachycardia and thereby terminate it. It is indicated for patients who cannot be terminated by drugs or who cannot use drugs, such as patients with cardiac insufficiency or women during pregnancy. Of course, the function of esophageal pacing is not only to stop the tachycardia, but also to determine the cause of the tachycardia, such as atrioventricular nodal tachycardia or atrioventricular tachycardia. (4) Electrical resuscitation: It is only suitable for patients with supraventricular tachycardia combined with syncope or unstable vital signs, or for patients with supraventricular tachycardia that cannot be terminated by other pharmacological or non-pharmacological treatments, and is a very effective way to redirect the termination of tachycardia by extracorporeal current. However, it is generally not used because it is invasive, requires anesthesia, and is difficult to accept in most patients. The treatment of paroxysmal supraventricular tachycardia is now uncontroversial in the medical community, and radiofrequency ablation is definitely recommended. This is because radiofrequency ablation therapy can achieve a radical cure, and the procedure has a high success rate, low risk, and a low recurrence rate. In contrast, drug therapy can only terminate a portion of supraventricular tachycardia and has too many side effects for long-term use and is of very little value in preventing supraventricular tachycardia attacks.
