Ventricular flutter is a heart condition that occurs when the heart's electrical system malfunctions, causing the ventricles to beat too quickly and out of sync with the atria. This can lead to a dangerous arrhythmia, and may require immediate medical attention. Some common synonyms for ventricular flutter include ventricular tachycardia, ventricular fibrillation, and rapid ventricular contractions. These terms are all used to describe abnormal heart rhythms that can be life-threatening if left untreated. If you experience any symptoms of ventricular flutter or other heart conditions, such as chest pain, dizziness, or shortness of breath, seek medical attention immediately.
