Atrial flutter is a type of heart rhythm disorder in which the heart’s upper chambers (atria) beat too quickly. In atrial flutter, your heart’s upper chambers (atria) beat too quickly . This causes the heart to beat in a fast, but usually regular, rhythm.20 Kas 2020

What can cause a ventricular arrhythmia?
Read moreCan stress cause ventricular fibrillation?
Chronic stress can lead to reduced heart rate variability, increased QT dispersion and reduced baroreceptor sensitivity. Patients with greatest changes in the cardiac neural regulation associated with increased sympathetic activity due to stress have the greatest risk for developing fatal ventricular arrhythmias [9].
Read moreWhat is the first treatment for ventricular fibrillation?
The first response to V-fib may be CPR . This will keep your blood moving to important organs. Defibrillation. This is an electrical shock that is delivered to your chest wall to restore normal rhythm.
Read moreWhat medication is given during ventricular fibrillation?
In acute ventricular fibrillation (VF), drugs (eg, vasopressin, epinephrine, amiodarone ) are used after three defibrillation attempts are performed to restore normal rhythm.
Read moreHow does ventricular fibrillation change the ECG?
ECG features of ventricular fibrillation The ECG shows irregular waves with varying morphology and amplitude . No P-wave, QRS complex or T-wave can be seen. This is pathognomonic (unique) to ventricular fibrillation and must not be confused with any other arrhythmia.
Read moreIs there cardiac output during ventricular fibrillation?
During VF, ventricular activation is so rapid and chaotic that the myocardium only trembles without any coordinated contraction. As a result, cardiac output is absent , and death occurs.
