What is Vtach on ECG?

Ventricular tachycardia refers to a wide QRS complex heart rhythm — that is, a QRS duration beyond 120 milliseconds — originating in the ventricles at a rate of greater than 100 beats per minute.

Why does Vtach happen?

Ventricular tachycardia (VT or V-tach) is a type of abnormal heart rhythm, or arrhythmia. It occurs when the lower chamber of the heart beats too fast to pump well and the body doesn’t receive enough oxygenated blood.

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 most common cause of Vtach?

Sometimes it is not known what causes ventricular tachycardia, especially when it occurs in young people. But in most cases ventricular tachycardia is caused by heart disease, such as a previous heart attack, a congenital heart defect, hypertrophic cardiomyopathy, dilated cardiomyopathy, or myocarditis.

What do you do for Vtach?

If you have ventricular tachycardia, you may be given medications called anti-arrhythmics by mouth or IV to slow the fast heart rate. Other heart medications, such as calcium channel blockers and beta blockers, may be prescribed with anti-arrhythmic drugs.

What’s the difference between VFIB and V-tach?

The difference between the two is that in ventricular tachycardia, the lower chambers of the heart are beating much faster than they should but the overall process is happening in the right order. In ventricular fibrillation, the heart’s beating process isn’t happening in the right order.

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.

Which is worse atrial fibrillation or ventricular tachycardia?

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.

Does ventricular tachycardia go away?

Cardiac ablation.

This is also called catheter or radiofrequency ablation. Doctors use heat to destroy unusual heart tissue. This method treats the ventricular tachycardia and can cure it.

How is asystole treated?

Asystole is treated by cardiopulmonary resuscitation (CPR) combined with an intravenous vasopressor such as epinephrine (a.k.a. adrenaline). Sometimes an underlying reversible cause can be detected and treated (the so-called “Hs and Ts”, an example of which is hypokalaemia).

Can you survive asystole?

Overall the prognosis is poor, and the survival is even poorer if there is asystole after resuscitation. Data indicate that less than 2% of people with asystole survive. Recent studies do document improved outcomes, but many continue to have residual neurological deficits.

What happens when a patient is in 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).

Do you pace asystole?

Transcutaneous pacing appears to offer no benefit in patients with asystolic cardiac arrest, even when it is performed as early as possible by EMTs in the field. Our data suggest that the widespread implementation of early transcutaneous pacing for out-of-hospital asystolic cardiac arrest would be ineffective.

What rhythms could you pace?

For pacing readiness (i.e. standby mode) in the setting of acute myocardial infarction (AMI) with the following:

  • Symptomatic sinus bradycardia.
  • Mobitz type II second-degree AV block.
  • Third-degree AV block.
  • New left, right or alternating bundle branch block or bifascicular block.

Can you touch a patient while pacing?

It is safe to touch patients (e.g. to perform CPR) during pacing.
