A heart rate of more than 100 beats per minute is called tachycardia in medical terms. There are various heart rhythm disorders (also called arrhythmias) that can lead to tachycardia. In some cases, a rapid heartbeat is normal. For example, an elevated heart rate is normal during exercise or in response to illness, trauma, or stress. However, when someone suffers from tachycardia, a condition unrelated to normal physiological stress causes the heart to beat faster than normal. Tachycardia may not cause symptoms or complications.
Left untreated, tachycardia can impair normal heart function and lead to serious complications such as sudden cardiac arrest, death, stroke, and heart failure. Some treatments, such as surgery, medical surgery, medical procedures, or drugs, can help control a rapid heartbeat or manage other conditions that lead to tachycardia.
Some symptoms of tachycardia:
If your heart beats too fast, it may not supply enough blood to the rest of your body. This can lead to a lack of oxygen in organs and tissues. It can cause the following signs and symptoms of tachycardia:
- fainting (a.k.a. syncope)
- chest pain
- Heart palpitations are defined as a racing, uncomfortable or irregular heartbeat, or a fluttering sensation in the chest
- rapid pulse rate
- Lightheadedness
- difficulty breathing
People with tachycardia may have no symptoms and are first discovered during a physical examination or a heart-monitoring test called an electrocardiogram.
Cause:
This condition is caused by anything that disrupts the regular electrical impulses that can control the rate of the heart’s pumping activity. There are many things that can cause or contribute to a fast heart rate, including: There is a thing
- Consumption of stimulants such as cocaine and methamphetamine
- Sudden stress such as fear
- smoking
- hyperthyroidism (hyperthyroidism)
- drug side effects
- Inequality of electrolytes, mineral-related substances required to conduct electrical impulses
- high or low blood pressure
- heat
- exercise
- drinking too much alcohol
- Excessive drinking of caffeinated beverages
- anemia
Sometimes the exact cause of tachycardia cannot be determined.
type:
There are different types of tachycardia, classified according to what causes the heart to beat fast and what causes it to beat abnormally fast. The most common types of tachycardia are:
Atrial flutter:
When someone has atrial flutter, the atria of the heart beat very quickly, but at a constant rate. This high speed results in weak contractions of the atria. Atrial flutter is caused by irregular circuits occurring in the atria. Atrial flutter chapters may go away on their own or require treatment. Also, people with atrial flutter may have atrial fibrillation at other times.
Atrial fibrillation:
This is a rapid heart rate caused by chaotic and irregular electrical impulses in the upper chambers of the heart known as the atria. These signals are causing weak, rapid, uncoordinated contractions of the atria. Atrial fibrillation may be temporary, but some episodes will not end unless treated. This is the most common type of tachycardia.
Ventricular fibrillation:
This condition occurs when rapid, chaotic electrical impulses cause the heart’s lower chambers (ventricles) to vibrate instead of pumping the needed blood to the body. If an electric shock to the heart does not return the heart to its normal rhythm within minutes, this can be fatal for people. Ventricular fibrillation can occur during or after a heart attack. Most people who suffer from ventricular fibrillation have an underlying heart condition or have experienced a traumatic event, such as a lightning strike.
Ventricular tachycardia:
This is a rapid heart rate that begins with abnormal electrical signals in the lower chambers of the heart. A fast heart rate prevents the ventricles from filling and contracting efficiently and pumping enough blood to the body.
Supraventricular tachycardia:
This type of tachycardia is characterized by an abnormally rapid heartbeat that begins somewhere above the lower chamber of the heart. This type of tachycardia is caused by abnormal circuits occurring in the heart, usually present at birth, creating overlapping signal loops.
