What are the 7 lethal rhythms?

What are the 7 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 the 3 types of arrhythmias?

AV nodal re-entrant tachycardia (AVNRT): A fast heart rhythm caused by the presence of more than one pathway through the atrioventricular (AV) node. Atrial tachycardia: A rapid heart rhythm that starts in the atria. Atrial fibrillation: A very common irregular heart rhythm.

What kind of rhythm is Torsades de Pointes?

Torsades de Pointes is a type of very fast heart rhythm (tachycardia) that starts in your heart’s lower chambers (ventricles). Unlike a normal pulse rate of 60 to 100 beats a minute, a fast heartbeat in your ventricles (ventricular tachycardia) is more than 100 beats a minute.

What are the 2 life threatening arrhythmias?

Arrhythmias that start in the ventricle include ventricular tachycardia and ventricular fibrillation. These are serious, often life-threatening arrhythmias since the ventricles do most of the pumping.

What is the most lethal heart rhythm?

The most dangerous arrhythmia is ventricular fibrillation, in which your ventricles quiver rather than beat steadily in time with your atria. Your ventricles will stop pumping blood to the rest of your body, including your heart muscle.

Is SVT a lethal rhythm?

Supraventricular tachycardia (SVT) is generally not life-threatening unless you have heart damage or other heart conditions. However, in extreme cases, an episode of SVT may cause unconsciousness or cardiac arrest.

What is the most common arrhythmia?

The main types of arrhythmia are: atrial fibrillation (AF) – this is the most common type, where the heart beats irregularly and faster than normal. supraventricular tachycardia – episodes of abnormally fast heart rate at rest.

Which arrhythmia is the most serious?

The most serious arrhythmia is ventricular fibrillation, which is an uncontrolled, irregular beat. Instead of one misplaced beat from the ventricles, you may have several impulses that begin at the same time from different locations—all telling the heart to beat.

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.

How do you identify torsades de pointes on an ECG?

Torsades de pointes is a specific form of polymorphic ventricular tachycardia in patients with a long QT interval. It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the electrocardiogram (ECG) baseline.

What do you need to know about the EKG rhythm test?

Given a rhythm strip, identify Sinus, Atrial, Junctional and Ventricular dysrhythmias, and Atrioventricular Blocks. 4. Identify the appropriate nursing and medical interventions, and first line medications for ECG rhythms. 5. Score at least 85% competency on the posttest. 4 GLOSSARY

What are the ECG characteristics of sinus rhythm?

Sinus rhythms have the following ECG characteristics in common: One Sinus P wave for each qRs and similar to each other, PR and qRs intervals normal and constant PR intervals. ECG characteristics that vary are rate and rhythm.

What are the ECG rhythm characteristics of 2nd degree AV block?

ECG Rhythm Characteristics Ohio State University Medical Center ©OSU June 2006 Revised August 07 6 Rhythm P waves qRs Notes 2nddegree AV Block, Type I Round, upright, similar PRI: progressive lengthening until drop of qRs #P > #qRs 0.04-0.10 Cyclic pattern Inconsistent PRI Predictable drop of qRs after lengthening PRI

What does normal rhythm look like on a rhythm strip?

A rhythm strip may appear normal but when measured, the P-P and R-R intervals will reveal a variation of the rhythm (to be considered irregular the R-R must vary more than 0.12 seconds).
