A heart rate of more than 200 beats per minute is a relatively common arrhythmia, mostly seen in supraventricular tachycardia, atrial fibrillation, atrial flutter and other diseases, and severe ventricular tachycardia can also occur with a heart rate of more than 200 beats per minute. After the heart rate exceeds 200 beats per minute, the patient should go to the hospital in a timely manner, to clarify the type of arrhythmia and choose the corresponding treatment. Supraventricular tachycardia is less dangerous to the patient, while ventricular tachycardia may induce ventricular fibrillation, which can lead to sudden death. Patients who find this type of heart rate increase must be clearly diagnosed in order to prevent the arrhythmia from progressing to malignant arrhythmia. A heart rate of more than 200 beats per minute repeatedly will also lead to an increase in the work of the heart, and the insufficient supply of blood will easily lead to myocardial lesions.
