The rhythm of the heart is normally controlled by its natural pacemaker (the sinus node), which produces electrical impulses that create the heartbeat. A normal, healthy heart beats about 60 to 100 times per minute, depending on what a person is doing. However, when electrical abnormalities cause abnormal heart rhythms, or arrhythmia, you may experience palpitations, which feel like the heart is skipping, fluttering, or beating too hard or too fast. A person suffering from arrhythmia can feel these sensations in the chest, throat, or neck. Very severe heart rhythm abnormalities may cause fainting.
While heart arrhythmias can be due to a variety of conditions, doctors at Yale Medicine are experts at diagnosing and treating the underlying causes. “We offer a number of state-of-the-art treatments, including medications, lifestyle treatments, and the ablation procedure,” which is removal of tissue causing the problem, says Yale Medicine cardiologist Rachel Lampert, MD.
