A normal person’s heart rate should be 60 to 100 beats per minute, and a heart rate of 111 beats per minute is an increased heart rate, which is not normal. But if you want to judge whether it is serious or not, you have to judge it according to the cause of the increased heart rate. If it is physiologic tachycardia, it is not serious. If the heart rate is pathologic, such as atrial flutter, atrial fibrillation, supraventricular tachycardia, etc., it is more serious. 1. Physiologic tachycardia: tachycardia caused by exercise or drinking coffee does not require treatment and can be relieved by removing the triggers. 2. Pathological tachycardia: when pathological tachycardia occurs, it is necessary to go to the hospital in time to improve the electrocardiogram, cardiac ultrasound and other examinations, so as not to delay the condition and cause serious consequences. When arrhythmia occurs, it is necessary to consult a doctor offline in time, identify the cause of the disease under the guidance of the doctor, and timely treatment.
