In such a case, you should find a doctor in time for observation. If the accelerated heart rate occurs frequently or the heart rate continues to be accelerated, add a beta-blocker, such as metoprolol, to reduce the heart rate and improve the ventricular remodeling; if the accelerated heart rate is combined with tightness in the chest, chest pain, and shortness of breath, you should go to the hospital in time for monitoring of the vital signs, and perfecting of the electrocardiogram, cardiac ultrasound, and other examinations except for the recurrence of the heart infarction.
Heart attack is short for myocardial infarction, which is caused by coronary artery occlusion due to coronary atherosclerosis or thrombus embolism, which results in myocardial tissue necrosis due to ischemia and hypoxia in the corresponding coronary artery supply area, affecting the heart’s function.
The causes of accelerated heart rate after stent implantation in heart attack are as follows.
1.Arrhythmia after reperfusion
After coronary stent implantation, the originally occluded coronary artery will be reopened, and the corresponding myocardium will restore perfusion, and the myocardium will produce post-reperfusion arrhythmia due to the reopening of the blood flow, which can be manifested as accelerated heart rate, atrial or ventricular premature beats, and accelerated ventricular autonomic rhythm, etc. This condition usually does not require treatment, and can be treated on its own. Generally, this condition does not require treatment and can be relieved on its own. If the accelerated heart rate persists, metoprolol can be added to reduce the heart rate symptomatically.
2. Post-infarction complication: malignant arrhythmia
Malignant arrhythmia is a more dangerous type of post-infarction complication, due to myocardial ischemia and hypoxia for too long, resulting in irreversible myocardial damage, affecting myocardial conduction, resulting in accelerated heart rate. At this time, it is often combined with chest tightness, chest pain, sweating and other clinical manifestations, should go to the hospital in time to improve the relevant examination, to avoid serious consequences.
3. Physiological heart rate acceleration
The patient’s heart rate is accelerated due to nervousness during the operation or the use of intraoperative antihypertensive drugs, and the heart rate can return to normal after calming down or resting. No medication is needed.
If there is any discomfort, please consult a doctor for diagnosis and treatment according to the doctor’s instructions, and take the medication under the doctor’s guidance.
