A heart rate that exceeds 100 pulses per minute is referred to as tachycardia in the medical sense. Tachycardia may result from a number of various types of irregular heart rhythms called arrhythmias. Fast heart rates are not always a cause for concern, it is important to recognize this. For example, the heart rate typically rises in response to physical activity or tension.
Tachycardia may not cause symptoms or complications; however, it may indicate a medical condition that calls for immediate attention. Certain types of tachycardia can lead to severe health complications if left untreated. These complications may include heart failure, stroke, or sudden cardiac mortality.
The various types of tachycardia should be understood. Among the most common types of tachycardia that are caused by irregular heart rhythms are atrial filtration, atrial flutter, ventricular tachycardia, ventricular fibrillation, and supraventricular tachycardia.
Atrial fibrillation is the most common type of tachycardia that you should be cognizant of. Chaotic, irregular electrical signals originate in the upper chambers of the heart, called the atria. These signals cause a fast heartbeat to begin. Some episodes of atrial fibrillation may be transient; however, they will not subside without treatment.
Atrial flutter is similar to atrial fibrillation; however, the pulse’s rhythm is more structured. These episodes of atrial flutter may resolve spontaneously or require medical intervention. Individuals who have atrial flutter frequently experience it at other times.
As was previously mentioned, some people with tachycardia show no symptoms. The fast pulse may be detected during a physical examination or cardiac testing for an unrelated reason. Tachycardia symptoms may include shortness of breath, fainting, lightheadedness, and a rapid pulse.
A multitude of factors can induce tachycardia. If you are experiencing symptoms of an abnormally fast heartbeat, it is recommended that you schedule a health examination. It is essential to seek immediate medical attention if you experience chest pain, shortness of breath, weakness, vertigo, or fainting or near fainting.
Ventricular fibrillation, a type of tachycardia, is an emergency that calls for immediate medical intervention. During ventricular fibrillation, blood pressure experiences an abrupt decrease. As a consequence of the heart’s inability to maintain blood circulation throughout the body, the individual’s pulse and respiration cease. A cardiac arrest is also called after the person collapses.
In the event that this occurs, provide CPR or dial 911. Administer hands-only CPR if you are hesitant to administer rescue breaths or lack training in CPR.
