Regurgitation occurs if the valve... 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 types of... Read More
