Arrhythmias, which are life-threatening or life-disturbing heart rhythm abnormalities, can be managed at The Hospital of Central Connecticut. Treatment usually involves medication, but in some instances, serious cardiac arrhythmias, such as ventricular tachycardia, do not respond well to drug therapy. Because of the high risk of cardiac arrest, a defibrillator implanted in the chest is often the best treatment. An implantable cardiac defibrillator (ICD) detects the presence of the potentially deadly arrhythmia and within seconds delivers an electrical charge to the heart that can restore normal rhythm. Sometimes a patient may be at risk of having a serious life-threatening arrhythmia but not yet meet the criteria to receive an ICD. In this case, the patient may benefit from temporarily wearing a lightweight wearable defibrillator to help assess long-term arrhythmic risk and develop a treatment plan. For other arrhythmias, a pacemaker may be more appropriate. This small device, implanted in the chest wall, monitors the heart rate and rhythm and can help the heart beat if it beats too slowly. The hospital has a pacemaker lab where routine checks are done to monitor pacemakers to make sure they are functioning properly and make adjustments in settings, if needed.
