The cardiovascular disease associated with the disorder of the heart rate or rhythm is called?

Appeared in: UPRVUNL - 2021

Explanation

Arrhythmia (or dysrhythmia) is the medical term for any disturbance in the normal rhythm of the heart.
This condition results from issues with the heart's electrical conduction system, which controls the rate and rhythm of heartbeats.
Arrhythmias can manifest as a heart rate that is too fast (tachycardia), too slow (bradycardia), or irregular.
The question asks for the name of the disorder itself, which is precisely the definition of arrhythmia.

Option A: Myocardial infarction (heart attack) is the death of heart muscle tissue. While it is a serious cardiovascular disease and can lead to arrhythmias, it is not the definition of a rhythm disorder.
Option B: Angina pectoris is chest pain that occurs when the heart muscle doesn't get as much blood as it needs. It is a symptom of underlying heart disease, not a rhythm disorder itself.
Option C: Ischemia is a general term for inadequate blood supply to a part of the body. Myocardial ischemia (reduced blood flow to the heart) is a common cause of arrhythmias, but it is the cause, not the rhythm disorder itself.

Clinical Relevance

Nursing practice connection: Knowing Definition of Arrhythmia helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A key nursing responsibility is the accurate assessment of a patient's heart rate and rhythm by checking the apical pulse for a full minute, especially if an irregularity is detected with the radial pulse.
Recognizing patient-reported symptoms like palpitations, dizziness, lightheadedness, or fainting (syncope) is crucial as they can indicate an underlying arrhythmia that requires further investigation with an ECG.
What if? If a patient's arrhythmia becomes unstable, causing a drop in blood pressure and altered mental status, it becomes a medical emergency requiring immediate intervention, such as synchronized cardioversion or defibrillation, depending on the rhythm.

How to Approach the Question

First, identify the core concept in the question stem. The keywords are "disorder of the heart rate or rhythm."
This is a definition-based question. Your task is to find the option that directly matches this definition.
Evaluate each option against the definition.
Myocardial infarction is tissue death, angina is pain, and ischemia is reduced blood flow. None of these are definitions of a rhythm disorder.
Arrhythmia literally translates to an abnormal rhythm, which directly matches the question's description.
Therefore, select the term that is a direct definition of the condition described.
