Early diagnosis is critical for more severe dysrhythmias, such as atrial fibrillation or Long QT syndrome. To determine if a patient has dysrhythmia, and identify the type, we use advanced technology to effectively diagnose, inform treatment and carefully monitor the condition.
What is dysrhythmia?
The term dysrhythmia comes from Greek, with the word 'dys-', meaning 'bad' and '-rhythmia,' which implies 'rhythm.' While dysrhythmia can be a term applied to brainwaves, it's most often a term relating to heart rhythm.
How do you diagnose dysrhythmia in nursing?
Diagnose the dysrhythmia. Determine the nursing plan of care. A patient may undergo an EP study in which electrodes are placed inside the heart to obtain an intracardiac ECG. This is used not only to diagnose the dysrhythmia but also to determine the most effective treatment plan.

How do you monitor a dysrhythmia?
One way that physicians monitor arrhythmias is by using ECG. To monitor infrequent arrhythmias, the physician uses ambulatory ECG, or event recording. The patient wears portable ECG devices that record arrhythmic events while the patient is away from the physician's office.
What Dysrhythmias require immediate intervention?
Cardiac rhythm disturbances such as bradycardia (heart rate < 50/min) and tachycardia (heart rate > 100/min) require rapid therapeutic intervention.

What causes dysrhythmia?
Narrowed heart arteries, a heart attack, abnormal heart valves, prior heart surgery, heart failure, cardiomyopathy and other heart damage are risk factors for almost any kind of arrhythmia. High blood pressure.
Which lead is best for ventricular dysrhythmias?
It is understood that the best ECG lead for monitoring arrhythmias is V1. The patient's symptoms were related to a wide QRS complex tachycardia, and V1 is capable of distinguishing ventricular tachycardia (VT) from supraventricular tachycardia (SVT) with aberrant conduction.
Why is cardiac monitoring important?
Cardiac monitoring enables clinicians to identify rapidly patients who require urgent intervention from those with benign conditions who can be discharged home.
What assessment is needed for a client experiencing Dysrhythmias?
Assess for and report signs/symptoms of cardiac dysrhythmias (e.g. irregular apical pulse, adult pulse rate below 60 or above 100 beats/minute, apical-radial pulse deficit, syncope, palpitations). Position patient to minimizes discomfort and facilitate respiration. Minimize anxiety with calm reassurance and education.
Which dysrhythmia is considered to be the most fatal and requires immediate treatment?
Ventricular fibrillation is an emergency that requires immediate medical attention. It's the most frequent cause of sudden cardiac death. Emergency treatment for ventricular fibrillation includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called an automated external defibrillator (AED).
What would be the priority goal in the nursing care plan for a client with a cardiac dysrhythmia?

What are 3 life threatening dysrhythmias?
Ventricular fibrillation, ventricular tachycardia and prolonged pauses or asystole are dangerous.
What is dysrhythmia?
Definition of dysrhythmia : an abnormal rhythm especially : a disordered rhythm exhibited in a record of electrical activity of the brain or heart.
What are the four classes used for cardiac dysrhythmias?
Classes of Drugs Used to Treat ArrhythmiasClass I - Sodium-channel blockers.Class II - Beta-blockers.Class III - Potassium-channel blockers.Class IV - Calcium-channel blockers.Miscellaneous - adenosine. - electrolyte supplement (magnesium and potassium salts) - digitalis compounds (cardiac glycosides)
What does it mean when a patient has a burst of sustained ventricular tachycardia
The burst of sustained ventricular tachycardia indicates that the patient has significant ventricular irritability, and antidysrhythmic medication administration is needed to prevent further episodes. The nurse should notify the health care provider after the medication is started.
What does the nurse teach the patient?
The nurse teaches the patient that sexual activity can be resumed when the incision is healed. ANS: C. The patient should avoid moving the arm on the ICD insertion site until healing has occurred to prevent displacement of the ICD leads. The other actions by the new nurse are appropriate for this patient.
What is the QRS complex?
The QRS complex represents ventricular depolarization. The P wave represents the depolarization of the atria. The PR interval represents depolarization of the atria, atrioventricular node, a bundle of His, bundle branches, and the Purkinje fibers. The Q wave is the first negative deflection following the P wave and should be narrow and short.
What is sinus tachycardia?
The patient has sinus tachycardia, which may have multiple etiologies such as pain, dehydration, anxiety, and myocardial ischemia. Further assessment is needed before determining the treatment. Vagal stimulation or -blockade may be used after further assessment of the patient.
Can electrical cardioversion be used for sinus tachycardia?
Electrical cardioversion is used for some tachydysrhythmias but would not be used for sinus tachycardia. When analyzing an electrocardiographic (ECG) rhythm strip of a patient with a regular heart rhythm, the nurse counts 30 small blocks from one R wave to the next.
Is ventricular fibrillation a QRS?
Ventricular fibrillation is irregular and does not have a consistent QRS duration. DIF: Cognitive Level: Apply (application) The nurse notes that a patient's heart monitor shows that every other beat is earlier than expected, has no visible P wave, and has a QRS complex that is wide and bizarre in shape.
What are the risk factors for dysrhythmia?
Risk factors that could contribute to dysrhythmia include: Advancing age: People over the age of 60 are more likely to develop dysrhythmia. Congenital heart defects: Certain structural or functional heart problems may be present at birth.
What is the most common type of dysrhythmia after heart surgery?
Healing after heart surgery. There are many dysrhythmia types –with different causes, symptoms and treatment needs. The most common is atrial fibrillation (AF), which occurs when the upper chambers of the heart, or atria, fibrillate. This means that they beat very rapidly and irregularly.
How do you know if you have heart arrhythmia?
That’s why regular checkups are so important. Symptoms like these may be noticed on a regular basis or every once in a while: Chest pain or tightness. Dizziness or lightheadedness.
What is it called when your heart beats too fast?
Your heart may beat too quickly, called tachycardia; too slowly, bradycardia; or with an irregular pattern. Dysrhythmias can range from completely harmless to life-threatening ...
What is the purpose of electrodes at the catheter tips?
Electrodes at the catheter tips use heat, extreme cold or radiofrequency energy to damage (ablate) a small spot of heart tissue and create an electrical block along the pathway that’s causing your dysrhythmia. Device implantation: You may be a candidate for a pacemaker or implantable cardioverter-defibrillator (ICD).
What is the procedure called when you have a maze in your heart?
Surgery. Maze procedure: During this procedure, a surgeon makes a series of incisions in the upper half of your heart (atria) to create a pattern (or maze) of scar tissue to interfere with stray electrical impulses that cause some types of dysrhythmia.
How to stop supraventricular tachycardia?
Vagal maneuvers: You may be able to stop certain dysrhythmias, like supraventricular tachycardia, by using maneuvers that include holding your breath and straining, dunking your face in ice water or coughing. These actions affect the vagus nerves that control your heartbeat, often causing your heart rate to slow.
What is the meaning of dysrhythmia?
Definition of Dysrhythmia. If you're a dancer or a musician, you know that rhythm is important to keeping a song or dance going on cue. The same kind of concept applies to the heart. It has a certain rhythm to its heartbeat. If that rhythm is disturbed, we call it a dysrhythmia, also known as arrhythmia or irregular heartbeat, it's all the same.
Where do ventricular arrhythmias occur?
Unlike SVT, ventricular arrhythmias arise in the ventricles, the two large, lower chambers of the heart. The most serious cardiac arrhythmia is a type of ventricular arrhythmia called ventricular fibrillation (v-fib, or VF), where the lower chambers just quiver instead of pump, preventing adequate blood flow.
How many chambers does the heart have?
Your heart has four main chambers. There are two upper, smaller, chambers called atria and two lower chambers, chambers called ventricles. If the arrhythmia arises in the electrical system of the heart that's above the, or supra-, the ventricles, it's called a supraventricular arrhythmia.
What is the meaning of tachycardia?
The term tachycardia, in supraventricular tachycardia, implies an abnormally fast rhythm. The word 'tachycardia' comes from 'tachy-,' meaning 'rapid,' and '-cardia,' which implies a heart action. So, we have a fast action of the heart (fast heart rate) arising from above the ventricles, a supraventricular tachycardia.
What is the best way to prevent V-Fib?
To prevent v-fib from occurring again, anti-arrhythmic medication can be given, such as beta blockers, or an implantable cardioverter-defibrillator (ICD) can be placed . An ICD monitors a person's heart rhythm and sends signals that pace the heart or reset the heart's rhythm altogether if necessary.
How to stabilize a Rican heart rate?
To stabilize Rica's heart rate, the doctor would probably administer an antiarrhythmic drug. An example of this would be beta-blockers, which reduce stress on certain parts of the body, such as the heart and the blood vessels in the brain. Such medication lowers blood pressure thereby protecting against heart attacks.
Do premature heart beats cause a person to skip a beat?
These usually do not cause a person any symptoms. However, if symptoms do arise, then the person experiencing premature beats may feel like their heart is fluttering in their chest or skipped a beat. Such arrhythmias usually do not require any treatment.
