Supraventricular tachycardia can be treated with medication. Supraventricular tachycardia can occur in patients of different genders and ages, and the medication should be individualized according to the patient’s condition, and the commonly used medications include adenosine, calcium channel blockers, digitalis, and so on. 1. Patients without comorbidities: If the patient has simple supraventricular tachycardia without heart failure and other comorbidities, adenosine, calcium channel blockers and other drugs can be used. (1) Adenosine: the first choice for supraventricular tachycardia is adenosine, which has rapid onset of action and fast disappearance of side effects. Side effects include chest pressure, facial flushing, atrioventricular (AV) block, dyspnea, and tracheal spasm, etc.; atrioventricular (AV) block of more than II degree, pathological sinus node syndrome, known or estimated bronchial stenosis or bronchospasm, and allergy to adenosine are contraindicated. (2) Calcium channel blockers: If adenosine is ineffective, calcium channel blockers, such as verapamil, can be used instead. Common side effects include hypotension, constipation, nausea, atrioventricular block, palpitations, etc.; it is not suitable for patients with heart failure, hypotension, wide QRS wave tachycardia, or when the diagnosis of supraventricular tachycardia is not yet clear. 2. Digitalis drugs (cediran) are preferred for patients with heart failure; side effects of these drugs include gastrointestinal reactions, arrhythmia, visual changes, etc.; they are contraindicated in bradycardia, obstructive heart disease, acute myocardial infarction, and hypokalemia. If you have supraventricular tachycardia, please go to the hospital in time and cooperate with the doctor to avoid delay.
