A rapid heartbeat is a condition in which the heart beats faster than regular rates. Sometimes, it is normal for heart rates to temporarily rise during exercise, physical exertion or as a response to normal physiological stress or trauma.
An anal fistula is defined as an infected tunnel that develops between the skin and the muscular opening at the end of the anus.
Sudden cardiac arrest in sports as a tragic event is the leading cause of premature death in competitive athletes. During sports participation or exercise, sport-related cardiac sudden deaths have been occasionally reported despite low incidences worldwide. Sports-related sudden cardiac arrest can even cast a negative light on sports and exercise in general, therefore obscuring the health benefits of regular exercise. The answer remains unclear why this life-threatening condition could suddenly kill athletes who had never presented with any signs and symptoms of cardiac disease. The program on cardiac screening and other measures recommended by the expert cardiologist to prevent sudden cardiac death is extensively considered an important key.
According to the International Travel Health Guide 2019 online edition, the probabilities of acquiring certain diseases or having an accident while traveling, depend largely on where you travel and what you are doing while traveling.

Chronic venous insufficiency (CVI) refers to a condition when the venous wall and/or valves in the lower extremities do not work properly, making it more difficult for blood to return to the heart from the legs. CVI is caused by damaged or weakened valves and vein wall due to aging and prolonged sitting or standing as well as reduced mobility. As a result, blood can flow backwards and pool or collect in these veins, leading to swelling in the lower legs and ankles.
For patients with cancer, the immune system tends to be lower than average. If infected with COVID-19, they are at a higher risk of developing severe symptoms, and their bodies are less capable of fighting off the COVID-19 virus. Therefore, it is highly important that all cancer patients receive the COVID-19 vaccination as soon as possible to reduce the potential risk of death that could occur.
Pinguecula and pterygium are the common degenerations of the conjunctiva. A pinguecula is characterized by a yellowish raised growth on the conjunctiva typically at the nasal or temporal conjunctiva near the edge of cornea. Pterygium is the triangular shape of vascularized conjunctival tissue on the cornea and it invades the cornea (known as fibrovascular invasion of the cornea). Pterygium may start as a pinguecula that can remain small or grow large enough to cover some parts of the cornea. The body of a pterygium usually appears red with noticeable blood vessels. Redness depends on the growth of abnormal blood vessels. If it is left untreated, pterygium sometimes advances towards the center of the eye, affecting vision. They are not tumor. Generally, pinguecula and pterygium form in the corner of the eye near the nose. However, they may develop in the temporal of the eye and often both eyes are involved.
Vascular access problems can usually develop in patients who need frequent administration of intravenous fluids or drugs and blood transfusion.
