What happens during asystole?
Asystole, colloquially referred to as flatline, represents the cessation of electrical and mechanical activity of the heart. Asystole typically occurs as a deterioration of the initial non-perfusing ventricular rhythms: ventricular fibrillation (V-fib) or pulseless ventricular tachycardia (V-tach).
What is asystole rhythm?
Asystole (ay-sis-stuh-lee) is when there’s no electricity or movement in your heart. That means you don’t have a heartbeat. It’s also known as flatline. That’s because doctors check the rhythm of your heart with a machine called an electrocardiogram — also called an ECG or EKG.
What is a shockable rhythm?
Shockable rhythms are rhythms that are caused by an aberration in the electrical conduction system of the heart.
What is VF heart rhythm?
Ventricular fibrillation (V-fib) is a dangerous type of arrhythmia, or irregular heartbeat. It affects your heart’s ventricles. Your heart is a muscle system that contains 4 chambers; the 2 bottom chambers are the ventricles. In a healthy heart, your blood pumps evenly in and out of these chambers.
Is asystole death?
Even in the rare case that a rhythm reappears, if asystole has persisted for fifteen minutes or more, the brain will have been deprived of oxygen long enough to cause severe hypoxic brain damage, resulting in brain death or persistent vegetative state.
Does asystole mean dead?
Zero electrical activity
In Asystole your patient’s heart is DEAD, Zero electrical activity. Asystole is defined as a cardiac arrest rhythm in which there is no discernible electrical activity on the ECG monitor.
What happens if you flatline?
Asystole (aka flatline) is the complete absence of any detectable electrical activity of the heart muscle. It appears as a flat line on the monitors. Clearly this is the worst type of cardiac arrest and there’s little chance of coming back from it.
Is atrial fibrillation a shockable rhythm?
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.
Why is V fib worse than AFIB?
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.
When does bradyasystole occur with or without a pulse?
Bradyasystole with a pulse is often accompanied by a significant decrease in cardiac output, leading to hypotension and/or syncope. Bradycardia with or without a pulse occurs frequently during cardiac arrest, either as the initial rhythm, during the course of resuscitation, or following electrical defibrillation.
How is bradyasystolic arrest a perplexing disorder?
Bradyasystolic arrest is not just a disorder of rhythm generation or propagation: it is a perplexing syndrome characterized by such rhythm disturbances accompanied, in many cases, by profound depression of myocardial and vascular function. The causes of the latter derangements have yet to be elucidated.
Are there any bradyasystolic patients who have OHCA?
Atrioventricular (AV) conduction disorders might lead to OHCA, but the prevalence of AV-conduction disorders and other bradyasystolic rhythms in OHCA is unknown. These patients might benefit from pre-hospital pacing.
When to use atropine or epineoxine for bradyasystole?
Secondary bradyasystole is present when factors external to the heart’s electrical system cause it to fail (e.g., hypoxia). It is unclear why conventional treatment of bradyasystolic cardiac arrest with atropine, epinephrine, or electrical pacemakers rarely results in survival to hospital discharge.
