A heart rate of 120 beats/min when standing up and 80 beats/min when lying down may be a normal physiological phenomenon that requires no special treatment, or there may be disease problems, including sick sinus node syndrome, atrial fibrillation, etc., which can usually be treated with medication.
1. Physiological factors: the body is in a state of activity when standing up, especially after exercise, the heart rate can reach 120 beats per minute, while lying down, the heart’s beating frequency will also decline, may be reduced to 80 beats per minute. This is a normal physiological performance, if there are no other unusual symptoms, such as dyspnea, panic and shortness of breath, generally no special treatment.
2. Pathologic factors:
(1) Sick sinus node syndrome: For patients with sick sinus node syndrome, the phenomenon of bradycardia and tachycardia usually occurs alternately, and is accompanied by dizziness, fatigue, blurred vision and other symptoms. Atropine, scopolamine and other medications should be given as prescribed by the doctor, and a pacemaker should be installed if necessary.
3. Atrial fibrillation: In the case of atrial fibrillation, it is often accompanied by increased heart rate and symptoms of chest tightness and shortness of breath, which may be aggravated after activities, and the heart rate will be slowed down after resting, and the discomfort will be relieved significantly, which can be treated with drugs to control the heart rate under the guidance of the doctor, such as β-blocker metoprolol, atenolol, etc. If the heartbeat is abnormal without obvious discomfort, it is necessary to give atropine, scopolamine and other drugs for treatment as instructed by the doctor, and if necessary, a pacemaker needs to be installed.
If the heartbeat is abnormal, in the absence of obvious discomfort, regular ECG monitoring can be performed. In general, you should pay attention to keep a calm mind, to prevent emotional over-excitement which may lead to a sudden increase in heart rate.
