Sinus Tachycardia

What is Sinus Tachycardia?

If you wish to understand ‘what is sinus tachycardia’, you need to know the role of the sinoatrial node in the body. Basically, the sinoatrial node is responsible for ensuring the right heart beat rhythm in the body. It is known as the pacemaker of the heart and it is responsible for the regular beating of the heart. The condition of sinus tachycardia is seen as an aberration, where the heart impulses are in the elevated region and the heart rhythm is much faster than the regular heart beat, averaging at about 110 beats per minute. Even though the normal heartbeat varies with age, the cases of sinus tachycardia cover instances where the regular heartbeat is higher than what is seen as normal.

Sinus Tachycardia Causes

In order to understand the major sinus tachycardia causes, you need to take a look at the main things which can lead to an elevated heartbeat. The simplest sinus tachycardia cause that is associated with this condition is exercising, something which is guaranteed to increase the heartbeat of a healthy person. Apart from exercises, there are some other simple factors, like stress, fright, flight and anger, which can lead to the condition of sinus tachycardia. These simple sinus tachycardia causes do not require proper treatment, but there are some other reasons which might ask you to take a look at the underlying causes of sinus tachycardia. Fever, anxiety and dehydration are some conditions which can lead to sinus tachycardia. Heart failure, Kawasaki disease, mercury poisoning, electric shock, drug withdrawal, malignant hyperthermia etc. are some major problems which can lead to a case of sinus tachycardia. Even though sinus tachycardia might not be persistent and might ease out with time, a case of inappropriate sinus tachycardia is something that definitely needs medical attention.

Inappropriate Sinus Tachycardia

The condition of inappropriate sinus tachycardia is considered to be quite problematic as the condition leads to a high resting heartbeat. The increase in heartbeat is quite abrupt with minimal amount of exertion, and this can have an impact on the overall health of your heart. Several doctors consider a case of inappropriate sinus tachycardia as quite serious, and there are several methods available for sinus tachycardia treatment. Even though sinus tachycardia might not be that serious, a chronic case definitely calls for proper medical assessment.
