Difference between Arrhythmia and Dysrhythmia




  • Main Difference

    Many medical terms are such that only the people concerned with the field have an idea about how they act on a human and what are the consequences. The two issues getting discussed in this space are arrhythmia and dysrhythmia, and they are similar and dissimilar to each other in various ways. This article looks at the critical variations between them, but if we select the primary difference. Then it goes as the problem with a human heart that leads to the regularly of its beating gets known as arrhythmia whereas an abnormality in a physiological rhythm, especially in the activity of the brain or heart gets known as dysrhythmia.

    Basis of Distinction Arrhythmia Dysrhythmia
    Definition The problem with a human heart that leads to the regularly of its beating. An abnormality in a physiological rhythm, especially in the activity of the brain or heart.
    Nature Change in the pattern of heartbeat that may get fast, slow or irregular at any time. Changing nature of the pulses where no proper pattern exists.
    Pumping Heart fails to pump blood frequently to all the parts that require it. Heart pumps blood in large or small amounts.
    Types Premature atrial contractions, Premature ventricular contractions (PVCs) and Atrial fibrillation. Atrial flutter, Paroxysmal supraventricular tachycardia (PSVT) and Accessory pathway tachycardias.
    Danger May become life threatening. May become serious if persists.

    Arrhythmia

    Arrhythmia, in simple words, gets defined as the problem with a human heart that leads to the regularly of its beating. No specific pattern exists within this issue where either the heart starts to beat too fast, it then gets too slow at times without any indications for some time, or there is no particular pattern for this pulse modulation. From this, two other terms come into consideration where A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Although most of such issues are harmless, since it is impossible to have one particular pattern all the time, but if the case is severe, then it becomes life threatening. During this problem, the heart fails to pump blood frequently to all the parts that require it and that cause damage to the brain, heart of organs associated because of the lack of flow. The explanation is such that a proper electrical system exists within the human heart and the rate and rhythm get controlled through it. Whenever the heart beats, a signal goes from the top to bottom ensuring all the parts get covered. This action helps in the heart to become contracted or expand as required and results in the pumping of blood. When these signals become weak, the process of pumping blood through the body also becomes troubled and means most of the parts related do not work properly. Many types of arrhythmia exist and various treatments to cure the issue exist.

    Dysrhythmia

    Dysrhythmia, in simple words, gets defined as an abnormality in a physiological rhythm, especially in the activity of the brain or heart. Although it may seem similar to other kinds of cardiac problems, there are some significant variations. While it has many variations, and most of them are not dangerous at all, it is always important to have a proper checkup. The human heart keeps on changing the rhythm based on the emotions we feel. When someone is happy, their heart may start beating at a fast rate, when someone is excited, the same thing happens. In the case when someone is sad or depressed, the beating slows down considerably. But if someone feels healthy for a long time and still there is abnormality then it becomes life threatening. We know that The human heart is a muscular pump divided into four chambers, where two atria located on the top, and two ventricles located on the bottom. What happens is that the pumping of blood starts because of the electrical signal sent from the upper part to the lower surface, whenever this signal is weak, the blood flows at a slower rate and hence the beating is more deliberate. When the signal is strong, the blood flows at a fast pace, and hence the beating is more rapid. According to the medical specialists, four main types of such issue exist. Premature (extra) beats, Supraventricular Arrhythmias, Ventricular arrhythmias and Bradyarrhythmias. The first category is the most common one among patients and considered harmless unless it persists for long.

    Key Differences

    • Arrhythmia gets defined as the problem with a human heart that leads to the regularly of its beating. On the other hand, Dysrhythmia gets defined as an abnormality in a physiological rhythm, especially in the activity of the brain or heart.
    • In simple terms, the arrhythmia is the change in the pattern of heartbeat that may get fast, slow or irregular at any time, whereas dysrhythmia is the changing nature of the pulses where no proper pattern exists.
    • The heart fails to pump blood frequently to all the parts that require it and that cause damage to the brain or body in dysrhythmia whereas the heart pumps blood in large or small amounts when it comes down to arrhythmia.
    • For both the issues, if the problem occurs for a short while no danger exists at all but if it starts persisting for a long time, then medical checkup become essential.
    • Primary types of arrhythmia include Premature atrial contractions. These are early extra beats that start in the heart’s upper chambers, called the atria, Premature ventricular contractions (PVCs) and Atrial fibrillation. On the other hand, primary types of dysrhythmia include Atrial flutter, Paroxysmal supraventricular tachycardia (PSVT) and Accessory pathway tachycardias.
