2021年9月21日 · Ventricular arrhythmias are abnormal heart rhythms that make the lower chambers of your heart twitch instead of pump. This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and don’t cause symptoms, some can have serious — or even deadly — effects on your body.

2023年10月13日 · Ventricular fibrillation. Rapid, chaotic electrical signals cause the lower heart chambers to quiver instead of squeezing in a coordinated way. This serious problem can lead to death if a regular heart rhythm isn't restored within minutes.

A ventricular dysrhythmia is a disturbance in the normal rhythm of the electrical activity of the heart that arises in the ventricles (Fig. 1). Experts estimate that sudden cardiac death occurs in approximately 300,000 cases each year in the United States, and up to one-third are attributable to ventricular fibrillation (VF) (Fig. 3).

2024年6月26日 · Ventricular arrhythmia (VA) is an abnormal heart rhythm that begins in the ventricles, the heart’s two lower chambers. The rhythm may be too fast or too uncoordinated for the heart to function...

Ventricular arrhythmias are abnormal heartbeats that originate in your lower heart chambers, called ventricles. These types of arrhythmias cause your heart to beat too fast, which prevents oxygen-rich blood from circulating to the brain and body and may result in cardiac arrest.

2023年10月13日 · Tests to diagnose a heart arrhythmia may include: Electrocardiogram (ECG or EKG). This quick test measures the electrical activity of the heart. It can show how fast or how slow the heart is beating. Sticky patches called sensors are attached to the chest and sometimes to the arms or legs.

Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Both are life-threatening arrhythmias most commonly associated with heart attacks or scarring of the heart muscle from a previous heart attack.

2022年5月9日 · A cardiac dysrhythmia (also called arrhythmia) is an abnormal or irregular heartbeat. An abnormal heart rate means that your heart rate is either too fast (typically over 100 beats per minute) or too slow (typically below 60 beats per minute).

2022年12月5日 · Ventricular arrhythmia is a condition where the pumping of the heart ventricles is abnormal. Ventricular arrhythmias produce a broad range of conditions, from premature ventricular complex to ventricular fibrillation. The clinical presentations can vary, from lack of symptoms to cardiac arrest. 1.

Our experts use their decades of training and experience to treat ventricular arrhythmias. Researchers from the University of Cincinnati often publish their work in the Journal of the American Heart Association, including research into the genetics of arrhythmias.
