High Heart Rate

The average heart beats between 60 and 100 times per minute. A heart rate of more than 100 beats per minute is regarded as high (medically termed tachycardia). Heart palpitations are not always dangerous. 

Heart Rate

The number of times your heart beats in a minute is your heart rate.When your heart pumps just the right amount of blood necessary for your body to function when you are at rest, this is known as your resting heart rate. When you’re calm and at rest, your heart rate is measured and this is your resting heart rate.Adults typically have a resting heart rate of 60 to 100 beats per minute (bpm). Depending on their age, children’s resting heart rates can be higher than adults.Individuals may have different resting heart rates. Your resting heart rate can also be affected by other variables, such as age, degree of exercise, and some drugs.

High Heart Rate

A heart rate that is greater than 100 beats per minute while at rest is referred to as a high heart rate , also known as tachycardia. It can be mild to potentially fatal and originate in either the upper or lower chamber of the heart.Your heart beats quicker than usual for a few seconds to several hours when you have high heart rate or tachycardia. 

Types of High Heart Rate

Atrial High Heart Rate – This condition starts in the heart’s upper chambers.It frequently starts in both adults and children between the ages of 25 and 40.

Atrial Fibrillation causing High Heart Rate – Heart chambers contract fast and erratically as a result of electrical activity in the atria overriding the heart’s normal pacemaker in this condition.It usually develops in conjunction with another cardiac disease.Individuals over 65 are more likely to be affected.

Atrial Flutter causing High Heart Rate – It is comparable to Atrial Fibrillation.The rhythms of the heart are more consistent in this condition.

Ventricular High Heart Rate – An irregular electrical impulse in the lower chambers causes an accelerated heartbeat in this condition.It could be brought on by drugs, genetic disorders that cause long QT syndrome, prior heart attacks, or other cardiovascular problems.

Ventricular Fibrillation causing High Heart Rate – This is a dangerous disruption of the heart.The ventricles tremble rather than beat in this condition.The body’s blood supply is compromised as a result.
