>Antiarrhythmics are designed to help your heart maintain a stable rhythm. Dr. Alfred Bove, a dive-medicine specialist, warns that some antiarrhythmics, when combined with exercise and lowered levels of potassium, could increase the risk of injury to the heart. Although such drugs do not normally interfere with diving, the arrhythmia for which the drug is being taken may itself preclude safe diving. A thorough consultation with a cardiologist and a dive-medicine specialist is essential if you take medication to control an abnormal heart rate and wish to consider diving.
