Ventricular tachycardia (VT) and ventricular fibrillation (VF) are lethal cardiac arrhythmias, claiming a quarter million lives per year from sudden cardiac death (SCD).
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).
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.
Ventricular tachycardia episodes may be brief and last only a couple of seconds without causing harm. But episodes lasting more than a few seconds (sustained V-tach ) can be life-threatening. Sometimes ventricular tachycardia can cause the heart to stop (sudden cardiac arrest).
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.
Tachycardia may not cause any symptoms or complications. But if left untreated, some forms of tachycardia can lead to serious health problems, including heart failure, stroke or sudden cardiac death.
The most serious arrhythmia is ventricular fibrillation, which is an uncontrolled, irregular beat.
Atrial flutter is important not only because of its symptoms but because it can cause a stroke that may result in permanent disability or death.
This can cause your heart to beat either too fast or slow. These arrhythmias may result from too much caffeine, alcohol or stress. They can also result from a serious health condition or heart problem. Atrial arrhythmias can range from harmless to life-threatening.
Without treatment, Torsades de Pointes can keep coming back or may lead to ventricular fibrillation, which can be deadly.
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.
The two nonshockable rhythms are pulseless electrical activity (PEA) and asystole and the two shockable rhythms are pulseless ventricular tachycardia and ventricular fibrilation. The ECG will distinguish asystole from ventricular fibrillation, ventricular tachycardia and pulseless electrical activity.
Atrial Flutter is a less severe heart condition than Afib. A person suffering from Atrial Flutter can, if not treated, effectively develop Afib. The symptoms of Atrial Flutter are less severe and easily controlled as compared to Afib.
Both heart diseases have the potential of becoming serious. However, many doctors and other health care professionals consider atrial flutter to be less serious than atrial fibrillation because flutter symptoms tend to be less severe and flutter waves have less risk of embolization (clot formation).
Does this affect my life expectancy? Most patients with atrial flutter lead an entirely normal life with modern drugs and treatments.
An implantable cardioverter-defibrillator (ICD) is a sophisticated device used primarily to treat ventricular tachycardia and ventricular fibrillation, two life-threatening heart rhythms.
Atrial Fibrillation Is Associated With a Worse 90-Day Outcome Than Other Cardioembolic Stroke Subtypes | Stroke.
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.
On average, a normal resting heart rate is between 50 and about 80 beats per minute. A resting heart rate over 100 beats per minute is considered an abnormally fast beat, or tachycardia.
Over time, untreated and frequent episodes of supraventricular tachycardia (SVT) may weaken the heart and lead to heart failure, particularly if there are other medical conditions. In extreme cases, an episode of SVT may cause unconsciousness or cardiac arrest.
One type of SVT, atrial fibrillation, can be dangerous because it can lead to blood clots, which increase stroke risk. Vagal maneuvers like splashing your face with cold water or coughing can slow down a rapid heartbeat. Treatments like medication or catheter ablation can permanently correct SVT.
Pulseless electrical activity (PEA) is a condition where your heart stops because the electrical activity in your heart is too weak to make your heart beat. When your heart stops, you go into cardiac arrest, and you don't have a pulse. PEA is a “nonshockable” heart rhythm, meaning a defibrillator won't correct it.
Asystole is a non-shockable rhythm. Therefore, if asystole is noted on the cardiac monitor, no attempt at defibrillation should be made. High-quality CPR should be continued with minimal (less than five seconds) interruption. CPR should not be stopped to allow for endotracheal intubation.
