A vasodilator is a type of medication that dilates or opens up blood vessels. Vasodilators work through a mechanism that causes changes in the muscles inside of the venous and arterial walls. This mechanism allows an individual's blood to flow more effortless through the blood vessels so the heart does not have to work so hard. There are three types of this medication: venous dilators, arterial dilators, and mixed dilators. Vasodilators are prescribed to individuals who have high blood pressure, pulmonary hypertension, preeclampsia, angina, or heart failure that require treatment. Vasodilators are not the preferred or first method of treating these diseases and conditions because they are known to be very potent. Vasodilators are used in cases where a patient's condition or disease is not able to be controlled through other means.
Vasodilators may produce serious side effects in affected individuals. Get the details on these now.
A pounding or fluttering heartbeat is medically referred to as heart palpitations, and these can occur in individuals who take vasodilators. Heart palpitations describe when an individual can feel that their heart is beating too fast, skipping beats, fluttering, pounding, or pumping too hard. Heart palpitations can manifest in several regions the torso, including the neck, chest, or throat. Palpitations may occur in individuals who take vasodilators due to the mechanism they use to help lower blood pressure. Vasodilators exert their action on the muscle tissue inside of the blood vessel walls to cause them to expand and allow a greater volume of blood to flow through. When blood vessels near the heart, neck, and chest become larger due to this medication, they are closer to other structures inside the body. Sensory nerves are included in the list of structures and tissues closer to where blood is pumping through the dilated arteries. When the nerves around any particular area in the neck, chest, or throat become activated by this pulsing because the vessels are dilated, they transmit this sensory information to the brain. The brain interprets this as heart palpitations in the affected area.
