Dizziness includes a range of symptoms, including feeling faint, unsteady, or weak. Sometimes people who feel dizzy say they feel like the room is spinning, which is commonly called vertigo.
Many adults experience dizziness at some point in time. While frequent dizzy spells can interfere with daily activities, they don’t typically signal a life-threatening condition.

Heart murmurs are not a specific disease, but rather a sound that your heart makes as it beats. Through a stethoscope, a heart murmur sounds like a whooshing or swishing noise. Heart murmurs can be congenital, meaning a condition you are born with, or may develop over time due to valve disease or other underlying issues.
There are two basic types of heart murmurs: innocent and abnormal. Many... Read More

Atrial fibrillation (or AFib) alone is not a life threatening condition, but it can lead to an increased risk of stroke and an increased risk of heart failure. Heart failure occurs when the heart doesn’t pump enough blood to meet the body’s needs.
In AFib, the heart doesn’t beat properly, which means it also can’t fill up completely to pump blood to the body. When... Read More

Orthostatic hypotension is a form of low blood pressure than happens when standing up from either a sitting or a lying position. It can make you feel dizzy or lightheaded, and it may even make you faint.

There are four valves in the heart: the tricuspid, pulmonary, mitral, and aortic valves. As blood exits each of the four chambers of the heart, the valves open to allow blood through and then close to prevent blood from flowing backward.
When one or more of the valves do not function properly, one of several types of heart valve disease can occur:
Regurgitation occurs if the valve... Read More

A recent study published in The Lancet medical journal resulted in news headlines that stents may not be effective for treating patients with chest pain. But as with any medical study, it’s important to examine the size of the study, the way that it was conducted, and the statistical significance of the data before changing any guidelines about patient treatment.
Stents are small wire... Read More

Tachycardia is the general term to describe a common heart rhythm issue where the heart beats too quickly. For diagnostic purposes, it’s typically defined as an elevated heart rate of 100 beats per minute or more at rest in adults. Resting heart rates vary by person, but a resting heart rate between 50 and 100 beats per minute is considered normal for most adults.
There are three basic... Read More

Blood pressure and heart rate are two different measurements. While they are frequently measured at the same time in the doctor’s office, they are distinctly different factors in heart health.
Blood pressure is the force exerted against the artery walls when blood pumps through the body, usually measured with two numbers. The top number (systolic pressure) measures the pressure as the heart... Read More

The vagus nerve is the longest of 12 cranial nerves and extends from the brainstem through the chest to the abdomen on each side of the body. It functions as part of the involuntary nervous system that controls unconscious processes in the body, such as regulating heart rhythm, regulating breathing, and digesting food.
Vasovagal syncope is one of the most common causes of fainting, which... Read More

Heart block is an abnormal heart rhythm where the heart beats too slowly, which results in the electrical signals being partially or totally blocked between the upper chambers (atria) and lower chambers (ventricles). Heart block is also called atrioventricular (AV) block.
Each heartbeat originates in the upper right chamber (atrium) of the heart in the sinus node, a bundle of specialized... Read More
