For patients with hypertension, it is important to pay attention to whether the blood pressure is stable. Therefore, many patients take blood pressure testing as a habit in their daily life. Of course, this is a good habit. It is an effective way to help patients understand their blood pressure fluctuations and find abnormal blood pressure in time, and also helps doctors better diagnose patients.
However, what many patients do not know is that, In addition to the fluctuation of blood pressure, there is also an important indicator that must be paid attention to at all times, that is, the change of heart rate, that is, the speed of heartbeat.
Most people may know that the normal range of heart rate is 60-100 beats/minute, but for patients with hypertension, the standard of normal heart rate may be more stringent. If patients do not pay attention to their heart rate changes or treat themselves according to previous standards, it may cause irreversible serious consequences.
Sudden death due to myocardial infarction after 21 years of hypertension!
Mr. Li, 65, is a patient with hypertension for 21 years. He started taking antihypertensive drugs at the age of 50 and has been taking antihypertensive drugs for 15 years. During this period, the drug use was relatively regular, but sometimes he forgot.
Recently, Mr. Li often felt flustered and out of breath. He thought it might be because of the hot weather in summer, so he didn't pay attention to it. Moreover, he found that his recent blood pressure was well controlled, sometimes even low, so he relaxed his vigilance and often forgot to use antihypertensive drugs. One day, Mr. Li went out on a long journey, and when he came back, he felt out of breath. After drinking a glass of cold water, he suddenly had chest pain and pale face. Before he could go to the hospital, he left forever.
The doctor explained that Mr. Li died suddenly because of myocardial infarction, which was closely related to the increase of his heart rate and blood pressure. In fact, Mr. Li's heart rate has always been on the high side. The doctor has prescribed medicine before, but he didn't care too much. He felt that his heart rate was about 90 beats per minute in most cases, which was also within the normal range. As long as his blood pressure was controlled, it would be OK to have a faster heart rate.
Hypertension patients must be alert to heart rate changes in summer!
When the weather is hot in summer, the metabolic rate of the body will increase, and the heart rate will also increase. In addition, people tend to be irritable in summer, and emotional fluctuations will further increase the heart rate. Mr. Li's frequent panic is actually the reaction of his heart beating faster, but he ignored it.
After high-intensity exercise, Mr. Li's heart rate will inevitably increase. After drinking ice water, the blood vessels will suddenly contract, which will also lead to an increase in blood pressure. And the increase of blood pressure and the acceleration of heart rate finally led to the tragedy.
Hypertension patients generally have increased heart rate, because one of the main mechanisms of hypertension is sympathetic nerve excitation, and the increased heart rate is a reflection of sympathetic nerve excitation. Therefore, the increase of heart rate and blood pressure interact. An increase in heart rate will increase the risk of elevated blood pressure, which will also damage the heart function and increase the heart rate.
In addition, strenuous exercise, mood fluctuation, smoking, high salt diet, etc. can also excite the sympathetic nerve, leading to an increase in heart rate. If these conditions occur in patients with hypertension, it will not only be harmful to the control of blood pressure, but also lead to accelerated heartbeat, causing serious consequences. Mr. Li's case is a typical case.
How do hypertensive patients manage their heart rate?
Research shows, The incidence of hypertension increased by 8% and the mortality of cardiovascular events increased by 25% every time the heart rate increased by 10 times/minute. Therefore, for patients with hypertension, in addition to the abnormal blood pressure, they also need to pay attention to their own heartbeat speed. For patients with hypertension, the heart rate should not be lower than 100 beats per minute, but should be 80 beats per minute.
That is to say, for patients with hypertension, if the resting heart rate is greater than 80 beats/minute, it indicates that the heart rate is too fast, and necessary intervention measures should be taken.
Clinically, For hypertensive patients with excessive heart rate, it is generally recommended to use drugs to slow down the heart rate. The most commonly used drugs are beta blockers, that is, lol drugs. The goal of drug use is to reduce the heart rate to 60-80 beats/minute. In addition, for patients with hypertension complicated with coronary heart disease, heart failure and other cardiovascular diseases, the standard is even lower, and it is recommended to be around 60 points.
In addition, hypertension patients also need to pay attention to daily lifestyle intervention, such as strengthening exercise, insisting on moderate exercise every day, and avoiding strenuous exercise; Low salt diet, smoking and drinking cessation; Avoid drinking strong tea or coffee; Maintain a healthy weight; Avoid emotional fluctuations and maintain a good attitude; Avoid overwork, staying up late, excessive pressure, regular work and rest, etc.
