Tachycardia: What is It?

It is highly probable that you have encountered the term “tachycardia” at some point in your existence. If not, tachycardia is a type of abnormal heart rhythm. Tachycardia is characterized by a heart rate that exceeds 100 beats per minute while the individual is at rest. When you are not engaging in physical activity, your heart rate typically fluctuates between 60 and 100 beats per minute.

Additionally, your heart is unable to fill with blood between beats as a consequence of its frequent beating. This may be dangerous if your heart is unable to provide all of your cells with the necessary oxygen and blood. It is unsurprising that you are advised to seek immediate medical attention when this occurs.

An understanding of the various types of tachycardia is essential. Certain types of tachycardia may be more severe and may recur on a regular basis. Tachycardias may be classified as mild to moderately detrimental. The form of tachycardia you have and the most effective method of managing it can be determined by a medical professional.

As a result, how can an individual determine whether they are experiencing tachycardia? It is unanticipated that certain individuals with tachycardia do not experience symptoms, while others may experience symptoms that range from mild to severe. Tachycardia may be identified by chest pain, vertigo, syncope, shortness of breath, rapid heart rate, and heart palpitations.

All of this raises the subject of the etiology of tachycardia. The heart typically responds to electrical signals from the sinoatrial (SA) node. The interval between heartbeats is determined by these signals. During periods of extreme emotional distress, anxiety, exercise, or terror, your heart may transmit signals more frequently for a brief period.

This condition is frequently referred to as sinus tachycardia and is typically resolved by sleep or relaxation. Additionally, an elevated heart rate may result from excessive caffeine or alcohol consumption, as well as substance or tobacco use. Stress, dehydration, high blood pressure, low blood sugar, pregnancy, and anemia are the most significant causes of tachycardia.

Certain types of tachycardia can lead to heart, liver, or kidney failure if the appropriate treatment is not pursued. Tachycardia may also lead to cardiomyopathy (deficient heart muscle), stroke, heart attacks, and blood coagulation.

In this regard, your physician will request your medical history and perform a physical examination. Further, they may request tests such as a Holter monitor, electrocardiogram (EKG), stress test, till table test, electrophysiology test, blood tests, cardiac imaging, or echocardiogram.
