What heart rhythms do you defibrillate?

Defibrillation – is the treatment for immediately life-threatening arrhythmias with which the patient does not have a pulse, ie ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT).

What are the 4 shockable rhythms?

Shockable Rhythms: Ventricular Tachycardia, Ventricular Fibrillation, Supraventricular Tachycardia.

What heart rhythms do you shock?

The two shockable rhythms are ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT) while the non–shockable rhythms include sinus rhythm (SR), supraventricular tachycardia (SVT), premature ventricualr contraction (PVC), atrial fibrilation (AF) and so on.

What rhythms can be Cardioverted?

Cardioversion can correct a heartbeat that’s too fast (tachycardia) or irregular (fibrillation). Cardioversion is usually done to treat people who have atrial fibrillation or atrial flutter.

What are the 5 lethal rhythms?

You will learn about Premature Ventricular Contractions, Ventricular Tachycardia, Ventricular Fibrillation, Pulseless Electrical Activity, Agonal Rhythms, and Asystole. You will learn how to detect the warning signs of these rhythms, how to quickly interpret the rhythm, and to prioritize your nursing interventions.

What are shockable and Nonshockable rhythms?

The algorithm consists of the two pathways for a cardiac arrest: A shockable rhythm – displayed on the left side of the algorithm. A non-shockable rhythm – displayed on the right side of the algorithm.

Do you defibrillate V fib?

Pulseless ventricular tachycardia and ventricular fibrillation are treated with unsynchronized shocks, also referred to as defibrillation. If a patient develops ventricular fibrillation during synchronized cardioversion with a monophasic defibrillator, pulselessness should be verified.

What are the 3 lethal heart rhythms?

Ventricular fibrillation, ventricular tachycardia and prolonged pauses or asystole are dangerous. Arrhythmias associated with very low potassium or magnesium or those associated with inherited causes such as QT prolongation are also serious.

What is the difference between V tach and SVT?

Tachycardia can be categorized by the location from which it originates in the heart. Two types of tachycardia we commonly treat are: Supraventricular tachycardia (SVT) begins in the upper portion of the heart, usually the atria. Ventricular tachycardia (VT) begins in the heart’s lower chambers, the ventricles.

How do you identify cardiac rhythms?

What are the different types of heart rhythms?

There are five main types of arrhythmias, described by the speed of heart rate they cause and where they begin in the heart.



Ventricular arrhythmias

  • Ventricular fibrillation.
  • Ventricular tachycardia.
  • Premature ventricular beats (PVCs)
  • Torsades de pointes.


How many EKG rhythms are there?

You will need to be able to recognize the four lethal rhythms. Asystole, Ventricle Tachycardia (VT), Ventricle Fibrillation (VF), and Polymorphic Ventricle Tachycardia (Torsade de pointes). Use this study guide and other resource books to review ECG interpretation.

How do you read EKG rhythms?


And you count until you hit 30 and however many appeared in the 30 in between those 30 boxes. You take that and multiply that by 10 and then you have your atrial. Rate. Next are the P waves regular.

How do you identify junctional rhythms?

Quote from Youtube:
I get 44 beats per minute which is right in that range we talked about with junctional rhythms right junctional rhythms will have an inherent rate between 40 and 60 beats per minute.

What rhythm looks like a shark fin?

Triangular QRS-ST-T waveform, also known as “shark fin pattern”, is an ECG presentation of ST segment elevation myocardial infarction with a unique wave composed by the QRS complex, the ST segment, and the T wave.

How do you memorize heart rhythms?

Quote from Youtube:
The little lump right the p-wave. What's the next big crossing thing that shows up your QRS.

What is a junctional rhythm?

A junctional rhythm is where the heartbeat originates from the AV node or His bundle, which lies within the tissue at the junction of the atria and the ventricle. Generally, in sinus rhythm, a heartbeat is originated at the SA node.

How do you interpret EKG rhythms like a boss?

Quote from Youtube:
There's two ways you can do this one I like to just get a piece of paper and Mark. Where those qrs's are and then March out that little piece of paper on.

Can a nurse read an ECG?

In an ideal situation, nurses would carry out and read the ECG, alert a consultant to a potential situation, and have the necessary drugs and paperwork prepared if they need to be transferred to a specialist treatment centre. This will potentially help in improving patient outcome by timely diagnosis,” he said.

What are the 3 types of ECG?

There are three main components to an ECG: the P wave, which represents depolarization of the atria; the QRS complex, which represents depolarization of the ventricles; and the T wave, which represents repolarization of the ventricles.

Can an ECG detect a blocked artery?

Can an electrocardiogram detect blocked arteries? No, an electrocardiogram cannot detect blocked arteries. Blocked arteries are usually diagnosed with a nuclear stress test, cardiac pet scan, coronary CT angiogram or traditional coronary angiogram.
