What does V-fib look like?
It has an appearance on electrocardiography of irregular electrical activity with no discernable pattern. It may be described as ‘coarse’ or ‘fine’ depending on its amplitude, or as progressing from coarse to fine V-fib.
What is ventricular arrhythmia?
Ventricular arrhythmias cause problems with the heart’s electrical system, leading it to beat too fast and, sometimes, chaotically. When an arrhythmia occurs in the ventricles, the heart has a hard time pumping enough blood to the body.
Can Vt be cured?
Ventricular Tachycardia (VT) in patients without structural heart disease. Ventricular tachycardia can also occur in patients with structurally normal hearts, unrelated to any history of coronary artery disease. It can occur in both the young and the old, and can be a benign, potentially treatable and curable condition …
Is ventricular tachycardia 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).
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 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 do ventricular arrhythmias feel like?
Heart arrhythmias may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms. However, sometimes it’s normal for a person to have a fast or slow heart rate.
What triggers ventricular arrhythmias?
Ventricular tachycardia most often occurs when the heart muscle has been damaged and scar tissue creates abnormal electrical pathways in the ventricles. Causes include: Heart attack. Cardiomyopathy or heart failure.
Does a pacemaker help ventricular tachycardia?
Overdrive pacing may prevent certain cases of ventricular arrhythmias, and antitachycardia devices may be useful in terminating paroxysmal ventricular tachycardia. In certain circumstances, internal cardioversion or defibrillation may be an alternative.
How do you treat VT with pulse?
VF or pulseless VT is treated by unsynchronised defibrillation; whereas other VTs can be treated with synchronised cardioversion. Most patients respond to low levels of energy (eg, starting at 50 J biphasic or 100 J monophasic).
What is the most common cause of ventricular tachycardia?
What does asystole look like?
Asystole is a flat-line ECG (Figure 27). There may be a subtle movement away from baseline (drifting flat-line), but there is no perceptible cardiac electrical activity. Always ensure that a reading of asystole is not a user or technical error.
Why is ventricular fibrillation fatal?
Sometimes triggered by a heart attack, ventricular fibrillation causes your blood pressure to plummet, cutting off blood supply to your vital organs. Ventricular fibrillation, an emergency that requires immediate medical attention, causes the person to collapse within seconds. It is the most frequent cause of sudden cardiac death.
What is the difference between atrial and ventricular?
One of the main differences between these two heart conditions is that ventricular fibrillation is life threatening if treatment isn’t begun immediately, while atrial fibrillation generally is not immediately life threatening, but can cause problems with the heart function that are very dangerous if not treated effectively.
What does ventricular fibrillation do?
Ventricular fibrillation. In a normal heart rhythm, an electrical signal travels from the heart’s upper chambers (atria) to the heart’s lower chambers (ventricles), causing the ventricles to contract and pump blood. In ventricular fibrillation, rapid, erratic electrical impulses occur in the ventricles.
