Tachycardia
**Tachycardia** is a condition where the heart beats faster than normal when a person is at rest. For most adults, a resting heart rate above 100 beats per minute is considered tachycardia. The heart usually speeds up during exercise or stress, but in tachycardia, the heart beats quickly even when a person is not active, which can lead to various health issues.
Having a heart that beats too quickly means it might not pump blood effectively to the body. This could result in symptoms like dizziness, shortness of breath, chest pain, or even fainting. In some cases, tachycardia might not cause noticeable symptoms but can still pose health risks if left unchecked.
There are different types of tachycardia, each stemming from problems in the heart's electrical system. Causes could include heart disease, high blood pressure, smoking, heavy alcohol use, or stress. In many cases, lifestyle changes, medication, or medical procedures can help manage and treat tachycardia.
