4. Low Heart Rate
Heart rate is one of the first things that doctors and nurses will monitor in a hospital, and it can tell them a lot about the current state of your health. One of the common symptoms that goes along with Legionnaires Disease is a lower-than-normal heart rate together with a fever, confusion, muscle pain, difficulty breathing and some of the other symptoms that have been mentioned on this list.
A lower heart rate together with a fever is considered one of the symptoms that are specifically characteristic of Legionnaires disease due to the fact that a fever normally accompanies a higher than normal heart rate instead. A lower heart rate can eventually lead to heart damage or seizure of the heart.
Experiencing a lower heart rate that becomes progressively worse should be an immediate trip to the emergency room, especially if an existing heart condition is present that already places strain on the heart.
