When the heart produces irregular rhythms that originate in its lower chambers, or ventricles, this condition is referred to as a ventricular arrhythmia. Three ventricular arrhythmias frequently treated by cardiologists include ventricular fibrillation, premature ventricular contractions, and ventricular tachycardia.
One of the most dangerous types of heart arrhythmias is ventricular fibrillation. This condition involves an irregular and uncontrolled heartbeat that can become chaotic and rapid, sometimes reaching as high as 300 beats per minute. This results in reduced blood flow from the heart to the brain and can lead to fainting. Other symptoms include chest pain, dizziness, and the sensation of an abnormal heartbeat. Immediate treatment for ventricular fibrillation typically involves CPR or cardioversion, a procedure which can shock the heart back into a normal rhythm. Doctors may recommend medications or an implantable cardioverter-defibrillator (ICD) to prevent future episodes. To improve blood flow, some patients may require coronary angioplasty or coronary bypass surgery.
Premature Ventricular Contractions
Also referred to as PVCs, premature ventricular contractions are extra heartbeats that begin in one of the heart’s ventricles. These contractions are common and frequently produce no symptoms. In some occurrences, the individual may notice a fluttering sensation, skipped or missed beats, or a pounding feeling in their chest. For many patients, treatment begins with lifestyle changes, such as eliminating tobacco and caffeine, which can both trigger a PVC. Beta blockers may be prescribed to suppress PVC episodes, and doctors may recommend radiofrequency catheter ablation therapy when other treatments fail.
Caused by a problem with the heart’s electrical system, ventricular tachycardia is a condition in which the heart’s ventricles beat too quickly. Episodes can be brief and may not cause symptoms, but longer instances can lead to dizziness, lightheadedness, or fainting. Common treatments for ventricular tachycardia include ICD insertion, pacemakers, cardiac ablation, cardioversion, and medications.
