Decrease in blood pressure after exercise may be a physiological phenomenon caused by exercise or a pathological phenomenon caused by coronary artery disease, cardiac arrhythmia, etc. General treatment and drug treatment can be given.
1. Physiological phenomenon: most of the peripheral blood vessels are in diastolic state after exercise, which causes a decrease in the volume of return blood and a decrease in cardiac output, thus leading to a drop in blood pressure. If you sweat a lot after exercise, the blood volume of the body can be reduced, thus leading to a drop in blood pressure. Usually, after replenishing water and resting for a period of time, the blood pressure can gradually rise to normal level.
2. Coronary heart disease: Exercise may cause coronary artery spasm, increase myocardial oxygen consumption, easily lead to coronary heart disease patients with insufficient blood supply to the myocardium, myocardial contraction decreased, cardiac output decreased, thus causing a drop in blood pressure. Should follow the doctor’s instructions to apply nitroglycerin and other expansion of coronary arteries, the application of β-blockers (such as metoprolol) to reduce myocardial oxygen consumption, thereby improving the situation of reduced blood pressure.
3. Arrhythmia: Exercise can induce tachyarrhythmia in patients, resulting in insufficient cardiac filling time and reduced cardiac output, thus leading to a drop in blood pressure. The patient should consult a doctor at the first time, and correct the arrhythmia through electrical cardioversion under the doctor’s guidance, so as to improve the situation of lowered blood pressure.
If you exclude the physiological phenomenon caused by the drop in blood pressure, you should go to a regular hospital in a timely manner, under the guidance of the doctor for standardized treatment, so as to avoid delays in the condition, resulting in adverse consequences.
