What does v-fib look like on the monitor?
Ventricular fibrillation (v-fib) is a common cause of out-of-hospital cardiac arrest. In this case, the heart quivers ineffectively and no blood is pumped out of the heart. On the monitor, v-fib will look like a frenetically disorganized wavy line.
How can you tell the difference between VT and VF?
VF and pulseless VT are both shockable rhythms. The AED cannot tell if the individual has a pulse or not….(Irregular Wide Complex Tachycardia)
| Regularity | There is no regularity. |
|---|---|
| QRS Complex | The ventricle complex varies. |
What are the two shockable rhythms?
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.
Which is worse AFib or VFib?
Ventricular fibrillation is more serious than atrial fibrillation. Ventricular fibrillation frequently results in loss of consciousness and death, because ventricular arrhythmias are more likely to interrupt the pumping of blood, or undermine the heart’s ability to supply the body with oxygen-rich blood.
What is the difference between AFib and VFib?
In AFib, the heart’s rate and rhythm will become irregular. Although serious, AFib is not typically an immediately life-threatening event. In VFib, the heart will no longer pump blood. VFib is a medical emergency that will lead to death if not treated promptly.
Which is worse VF or VT?
The prognosis of these arrhythmias is generally poor. Ultimately the prognosis depends on the nature of the underlying cause. The outlook for VT is slightly better than VF and some ventricular tachyarrhythmias (fast abnormal heart rates) are surprisingly well tolerated.
Do you shock VT with a pulse?
Under current resuscitation guidelines symptomatic ventricular tachycardia (VT) with a palpable pulse is treated with synchronised cardioversion to avoid inducing ventricular fibrillation (VF), whilst pulseless VT is treated as VF with rapid administration of full defibrillation energy unsynchronised shocks.
How do you identify Torsades de Pointes?
Symptoms of torsades de pointes include:
- heart palpitations.
- dizziness.
- nausea.
- cold sweats.
- chest pain.
- shortness of breath.
- rapid pulse.
- low blood pressure.
Do you Cardiovert or defibrillate torsades?
For those patients with hypotension or in cardiac arrest from Torsades de Pointes, electrical cardioversion should be performed. Synchronized cardioversion should be performed on a hemodynamically unstable patient in torsades who has a pulse, (100J monophasic, 50J Biphasic). Pulseless torsades should be defibrillated.
Is sinus tachycardia shockable?
Sinus Tachycardia: Non-shockable Not usually a surprise if it is triggered in response to regulatory changes e.g. shock. But if there is no apparent trigger then medications may be required to suppress the rhythm.
How to read an EKG rhythm strip?
In order to know how to read an EKG rhythm strip, you need to first be able to understand what normal sinus rhythm (NSR) looks like. You should be comparing every rhythm strip to NSR. Recognizing where the rhythm differs from NSR will help you identify the rhythm.
What are the EKG rhythms for ventricular rhythm?
EKG Rhythms Interpretation: Ventricular Rhythms: 1 Accelerated Idioventricular Rhythm. 2 Idioventricular Rhythm. 3 Premature Ventricular Complex (PVC). 4 Bigeminy premature ventricular complexes. 5 Trigeminy premature ventricular complexes. 6 (more items)
What is included in the EKG strips guide?
Our EKG strips guide provides information about many types of arrhythmias. For each practice EKG strip we provide multiple electrocardiogram tracings. Electrocardiogram analysis is provided using a concise summary of the EKG’s key features. Tracing features can be measured using our digital calipers.
What does a 6 second interval mean on an EKG strip?
▪ Denotes a 6 second interval on EKG strip ▪ Strip is marked by 3 or 6 second tick marks on the top or bottom of the graph paper ▪ Count the number of QRS complexes occurring within the 6 second interval, and then multiply that number by 10 ▪Using rate determination chart
