Hearts are all about love and romance, or so we happily liked to believe. Even though it stands for all things romantic, stuff that might be going inside this epitome of love might not be all that rosy, after all. When we talk about the heart, we can’t miss heartbeats. Everyone has a set pattern or a rhythm of a normal heartbeat. Some have a faster pace, and some have it slower than others. But have you heard of missing a heartbeat, or having irregular heartbeats? That’s what we’re going to talk about in this article. The heart normally beats between 60 to 100 times per minute. If it beats too fast, or too slow, too early, or too irregularly, the condition is called arrhythmia.
Types of Arrhythmia:
As mentioned above, arrhythmias are detected by the speed of the heartbeat and usually involve bradycardia and tachycardia with variations under these two categories.
Slow Heartbeat Or Bradycardia:
Bradycardia is a type of heartbeat that occurs when your heart beats so slowly that pumping enough blood throughout the body gets delayed. The entire functioning of the body slows down resulting in excessive fatigue, dizziness, and fainting. This might require correction with an electronic pacemaker to help your heart beat normally.
Why does bradycardia occur?
There are several reasons for bradycardia, of which, here we have two main reasons listed:
- Sick sinus syndrome: Malfunctioning of the sinus node, which is referred to as the heart’s natural pacemaker can slow down. Increasing age or disease may cause this condition.
- Heart block: The heart’s electrical system sends signals from the upper chambers of the heart (atria) to the lower chambers in a pattern causing a heartbeat. Heart block may occur when this signal gets delayed.
Coming to the other part of irregular heartbeats, it’s not just when you fall for someone that your heart starts beating faster. It could be severe enough if you simply ignore it, thinking it’s just high blood pressure. Sometimes when it beats faster, it might feel like drums are beating on your chest, and you can hear it loud. That is when you have tachycardia or rapid heartbeat.
So, what is tachycardia and what does it do to you?
Tachycardia refers to a heart rate that is abnormally high. Which means, that when the heart beats more than 100 beats per minute, the heart rate is so fast that it can cause missing some beats in between. This condition can occur both in children as well as adults.
- Sinus tachycardia: Sinus tachycardia can occur as a result of situations such as too much of cardio exercises, anxiety, and stress in excess, or fever. Thyroid disorders, anaemia, and low blood pressure also trigger sinus tachycardia.
- Atrial fibrillation (AF): Heart diseases, an overactive thyroid, or alcoholism are frequently associated with atrial fibrillation. Artificial fibrillation causes blood clots inside the heart, which increases the risk of having a stroke.
- Supraventricular tachycardia (SVT): Supraventricular tachycardia is a type of irregular heartbeat which starts with electrical signals above the heart’s ventricles which travel down an abnormal electrical pathway.
- Ventricular tachycardia (VT): Ventricular tachycardia is triggered by an electrical abnormality of within the ventricles which lowers the rate of pumping blood. In such cases, a person may become pulseless if not corrected immediately.
- Ventricular fibrillation (VF): Ventricular fibrillation is a rapid, chaotic rhythm, in which the ventricles of the heart fail to pump blood at all. It can be fatal it is not treated in time and converted to a normal rhythm. Ventricular fibrillation is usually a result of an underlying heart disease.
So, heart problems may not always look like a serious issue that you need to panic over. They can simply start with smaller problems which need to be addressed in time. There are quite a few ways to avoid arrhythmic heart beats and tachycardias like balanced exercises, yoga, etc., but it is necessary to keep your doctor informed of how your heart beats!
