What are examples of cardiac dysrhythmias?

Cardiac dysrhythmias are found in a vast range of conditions and may be defined in a number of ways, including by site of origin (e.g., supraventricular, ventricular, atrial), mechanism of disturbance (e.g., fibrillation, automaticity, reentry or triggered activity), rate of disturbance (e.g., tachycardia, bradycardia) …

What is the most common cardiac dysrhythmia?

Atrial fibrillation is the most common sustained arrhythmia, increases with age, and presents with a wide spectrum of symptoms and severity.

Is torsades VT or VF?

A: Torsades de pointes is a ventricular tachycardia, meaning that it is a fast heartbeat with the electrical activity from the ventricles. The ventricles are the two lower chambers of the heart that pump blood first from the right side of the heart to the lungs, and then from the left side out to the rest of the body.

What is dysrhythmia?

What is Dysrhythmia? Cardiac dysrhythmias are a problem with the rate or rhythm of your heartbeat caused by changes in your heart’s normal sequence of electrical impulses. Your heart may beat too quickly, called tachycardia; too slowly, bradycardia; or with an irregular pattern.

What causes cardiac dysrhythmias?

It can be life-threatening if the heart cannot pump enough oxygen-rich blood to the heart itself or the rest of the body. A cardiac dysrhythmia can be caused by many things, including problems with the heart valves, coronary artery disease, heart failure, drug use, and some medicines.

What is monomorphic and polymorphic VT?

Ventricular tachycardia should be described by type (monomorphic or polymorphic), duration (sustained or non-sustained) and heart rate — i.e. monomorphic VT non-sustained at a heart rate of 220 bpm or sustained polymorphic VT at a heart rate of 250 bpm.

Is torsades VFIB or Vtach?

A: Torsades de pointes is a ventricular tachycardia, meaning that it is a fast heartbeat with the electrical activity from the ventricles.

What are the causes of dysrhythmia in the heart?

Dysrhythmia causes. Dysrhythmia is caused by changes to your heart tissue. Dysrhythmia can also occur suddenly as a result of exertion or stress, imbalances in the blood, medicines, or problems with electrical signals in the heart.

What is the prognosis for cardiac dysrhythmia?

Prognosis: In many cases, the outlook for those with dysrhythmia is good, especially if they make lifestyle changes to mitigate symptoms. However, if the person also has coronary artery disease, congestive heart failure, or other heart muscle disorders, the outlook may vary.

What should a nurse know about cardiac dysrhhmias?

It is essential that nurses who care patients at risk for cardiac dysrhythmias have a thorough understanding of accurate electrode placement. They must also use current principles when determining the optimal leads to use in monitoring specific types of dysrhythmias.

What do you need to know about dysrhythmia education?

It is essential that institutions have emergency policies and procedures in place, along with a continuing competency education program and yearly refresher programs. The programs should include validation of dysrhythmia interpretation skills and problem solving of case studies.
