Aerobic exercise requires the heart, lungs and skeletal muscles to work hard in order to build strength and endurance. During exercise, most people experience an increased heart rate, increased breathing rate and muscle soreness. Pain or...
Supraventricular tachycardia, also known as paroxysmal supraventricular tachycardia, or PSVT, is a condition characterized by occasional bouts of rapid heart rate. The condition occurs when the electric impulse that travels through the heart to...
There are several heart disorders that involve an abnormal rate -- the heart may beat slower or faster than normal. The heart can also have various irregular rhythms. PSVT, or paroxysmal supraventricular tachycardia, is a disorder where the heart...
Under normal circumstances, average heart rates for non-athletes fall within a relatively narrow range of roughly 60 to 100 beats per minute. Temporary elevations of these rates commonly occur during exercise and other forms of physical activity....
According to the Centers for Disease Control and Prevention, heart disease is the leading cause of death in both American men and women. There are many types of heart disease that include irregular heart rhythm, atrial fibrillation, congenital...
A normal heart rate in an adult is between 60 and 100 beats per minute. An elevated heart rate is called tachycardia. Elevated heart rates occur in healthy individuals under certain circumstances. They can also indicate an underlying medical...
Exercise provokes changes in your heart muscle as it gains strength and pumps with greater efficiency. This transition frequently causes an irregular heart rhythm that may feel like a heavy thumping or an occasional flutter in your chest. Often,...
Your heart's rhythm is influenced by several organs including those in the nervous, cardiovascular and endocrine systems. Normally, the heart is able to restore a healthy rhythm when common influences, such as emotions or physical activity, cause...
The heart normally beats in a rotating cycle of contraction and relaxation. This elegantly coordinated action is controlled by electrical impulses, which normally move across the heart with precision and reliability. When something goes awry with...
Anxiety is a ubiquitous experience. When severe, it can indicate a psychiatric problem. Various medical conditions can cause anxiety. Before concluding that anxiety stems from psychological problems, a physician should assess the patient to rule...
Prenatal vitamins are designed to be used during pregnancy to provide extra nutritional support for the growing fetus. Children with poor prenatal nutrition may have increased risk of developing certain diseases later in life, including...
Adenosine is marketed under the brand names Adenocard and Adenoscan. Adenocard is used to treat certain types of cardiac arrhythmias with the goal of returning the heart to a normal beating rhythm. It is primarily used to treat paroxysmal...
Your heart rate provides important information regarding the health of your circulatory system during exercise. The American Heart Association recommends exercising at an intensity that causes your heart to beat at a range of 50 to 85 percent of...
Phenylephrine hydrochloride is indicated for congestion of the nose, sinus and eustachian tubes; paroxysmal supraventricular tachycardia (short bursts of rapid heart rate); anesthesia support; vascular failure in shock; eye conditions; and eye...
Aerobic and anaerobic exercise make the heart beat at a faster rate than when resting. Testing the heart rate by measuring the pulse during exercise is a common way of determining the intensity of your exercise. Tachycardia is the medical term for...
Supraventricular tachycardia -- SVT -- is a heart rhythm problem that is usually harmless but can be frightening and annoying. During an episode of SVT, the heart can go from beating a normal 70 to 80 beats per minute to 160 to 200 beats per...
Tambocor is the brand name of an antiarrhythmic medication called generically flecainide. It is used in the treatment of arrhythmia, which is the medical term for having irregular heartbeats. This prescription-strength medicine is used, according...
Lanoxin, generically called digoxin or digitalis, is used to treat heart failure and irregular heart rhythms such as atrial fibrillation. Lanoxin initially affects the nervous system to decrease conduction of electrical impulses in the heart...
A variety of factors cause increased heart rate, some transient and others persistent. While the brain and nervous system control the base heart rate, circulating hormones and other chemicals in the blood can trigger heart rate increases....
The painful, blistering skin rash known as shingles is caused by the varicella-zoster virus, which also causes chickenpox. Once you get chickenpox, the virus becomes dormant but remains in certain nerves. Medically called herpes zoster, shingles...
