Cardiac discomfort while riding a roller coaster may be normal. Sympathetic excitation caused by physiological reactions and pathological factors such as angina pectoris, cardiomyopathy, etc. can cause symptoms of cardiac discomfort when riding roller coasters.
Physiological reasons: when riding a roller coaster, people will be frightened, and at the same time, emotions will be very excited, which can cause sympathetic excitation, postganglionic fibers release norepinephrine. The heart is innervated by sympathetic nerves, and norepinephrine acts on the heart to cause enhanced cardiac contraction and accelerated heart rate.
Norepinephrine can also be released from the vasoconstrictor nerve fibers, causing vasoconstriction, resulting in temporary insufficiency of the blood supply to the heart, which in turn produces a feeling of discomfort.
2. Pathological causes: angina pectoris and cardiomyopathy can also cause myocardial ischemia, resulting in an uncomfortable feeling in the heart. If the uncomfortable feeling persists without relief, you should be alert to the presence of organic diseases and seek medical attention in time.
Usually have heart disease, or often feel uncomfortable with the heart should avoid riding roller coasters, choose some stimulation of small entertainment projects, and timely standardized treatment to avoid adverse consequences.
