Lyme Disease Symptoms and Signs

Irregular heartbeat and disturbances of the rhythm of the pulse. That Lyme disease actually causes palpitations of the heart is an indication of how seriously the disease affects the body. The palpitations will usually be accompanied by lightheadedness. However, while this disruption of the heart rhythms is a definitive symptom of Lyme disease, the palpitations themselves are not serious or life-threatening.
